Euston Station and HS2 – A 2023 Update

In 2017, I photographed the area to the west of Euston Station, with a focus on St. James’s Gardens, as this area was about to become the construction site for the expanded Euston Station, for the London terminus of HS2, a high speed railway that would run to Birmingham with branches to Manchester and the east Midlands.

Each year since 2017, I have made a return visit to the area around Euston Station, intending to photograph what was there before demolition, then the construction phase and finally the new Euston Station.

In recent years, the future of HS2 has been in doubt, and a couple of months ago, the Government announced that the northern sections would be dropped and that the London section between Old Oak Common and Euston Station would be paused.

In the latest HS2 6-monthly report to Parliament – November 2023, it was stated that delivery remains on track for “Old Oak Common in west London and Birmingham Curzon Street by 2029 to 2033”. There was no date given for completion of the section from Old Oak Common to Euston.

There is a list of all my previous HS2 posts at the end of this post, and after anticipating seeing a new station as the final post in this series, I now wonder whether I will ever get to see a new HS2 station at a redeveloped Euston.

The following map from the Media section of the HS2 website shows the route as it was still planned in 2022:

HS2_print_Infrastructure map_post IRP_220607_jpg

As well as pausing construction of the section from Old Oak Common to Euston, the November report to Parliament stats that “we will not proceed with Phase 2a, 2b or HS2 East”.

Much of the construction area is hidden behind panels, many of which have artwork and advertising that tells the story of what HS2 will bring to Euston, and the wider benefits of the project. Much of this now looks rather hollow and out of date, and includes the new Euston Station:

And as well as “building you a better Euston”, the following poster still states that HS2 will be “Connecting eight out of ten of Britain’s largest cities”, and will “More than double the number of train seats out of Euston in peak hours”:

And that improvements to the existing station will provide a “Bigger, better concourse, 100s of new seats, wider platform ramps”.

Extension of HS2 from Old Oak Common to Euston has been “paused”, and the November report to Parliament states that:

“We are going to scale back the project at Euston and adopt a new development led approach to the Euston Quarter which will deliver a station that works, is affordable and can be open and running trains as soon as possible. We will not provide design features we do not need and will instead deliver a 6-platform station which can accommodate the trains we will run to Birmingham and onwards and which best supports regeneration of the local area. In this way we will attract private funding and unlock the wider land development opportunities the new station offers, while radically reducing its costs to the taxpayer.”

But the most scary part of the new plans for Euston is this sentence in the November report:

“At Euston, we will appoint a development company, separate from HS2 Ltd, to manage the delivery of this project. We will also take on the lessons of success stories such as Battersea Power Station and Nine Elms, which secured £9 billion of private sector investment and thousands of homes.”

Whilst economically, Nine Elms has been considered a success in bringing in considerable (mainly overseas) investment to develop the area, the Nine Elms development seems to have resulted in the random placement of individually designed tower blocks, without any apparent cohesive design for the area. The towers look as if they have been randomly dropped from the sky, with a height and density to maximise profit rather than to add character and improve a key part of London.

Is this the future for Euston? A station hiding underneath another vision of Nine Elms, delivering enough cash from developers to complete the section from Old Oak Common to Euston along with the new station, but with a focus on the needs of developers, rather than a new the design and build of a new station that could have served as the London terminus of a growing railway to the north of the country.

In the following map, I have added a red line to show the area which had been cleared for the new station, and the tracks leaving the station to head to Old Oak Common (Map © OpenStreetMap contributors):

HS2 have a couple of photos in the Media section of their website which shows the scale of the site. The following is looking at the site from the north:

An aerial still of the HS2 Euston Station site, August 2022

And the following view is looking north, with Euston Station to the right:

An aerial still of the HS2 Euston Station site, August 2022

Both of the above photos are available to download from the Construction section of the HS2 media Gallery at this link.

I suspect that the main problem that HS2 has had is the name – High Speed 2.

The slightly shorter journey time from London cannot really justify the expense of the project, and the additional speed will only really benefit journeys much further north than Birmingham.

The main benefit that HS2 provides is extra capacity on existing rail lines, such as the West Coast Main Line (WCML).

Transferring high speed trains from the existing WCML onto HS2 would have released a significant amount of extra capacity which could have been used for freight, additional passenger train services between many of the places on the WCML route, as well as increasing the number of high speed trains.

However, calling the project Extra Capacity 1, or EC1 does not sound as exciting as HS2, although it would have been a better description of the real benefits.

I started my 2023 walk on a weekday, when hopefully it would be clear how much work was still underway. My route started in Clarkson Row, just to the west of Mornington Crescent, as here you can just about see over the wall, across the existing tracks, to where new tracks will be run as the railway heads from Euston to Old Oak Common:

Heading along Hampstead Road, and this is the view along the street, back towards Mornington Crescent. The main entrance to the site to the west of Hampstead Road is here:

There was still work underway, however according to HS2 press releases, what is happening now around Euston is “enabling work” rather than construction works, and there were utility works on the street, so I assume this means minor, low cost works which may make the project easier to get underway if and when it restarts.

One of the entrances to the main Euston site:

Look back along the Hampstead Road:

This is the main entrance from Hampstead Road to the main site around Euston Station:

There appeared to be very little happening, and the only vehicle that was running through the site was a road sweeper.

There is no sign of any elements of a new station, and the appearance of the site was much the same as last year. Parts of the site which were open last year have now been fenced off, so the site appears more enclosed than a year ago, but again, not much happening within the site.

There are three places where there is a change to last year, the first is the National Temperance Garden, described as “a temporary green space for all to enjoy”. It has been built on the site of the old National Temperance Hospital, and this is the view of the garden from Hampstead Road:

The large structure behind the gardens are offices and have been there for the last few years. The fencing between the gardens and Hampstead Road are standard HS2 Euston green security fencing and surround places on the site where there are no large panels.

Inside the gardens, which apparently has been “specially designed to be moved and re-used in the local area when the site closes”:

These buildings were home to the Maria Fidelis School:

To free up the school site, HS2 have built a new school between Drummond Crescent and Phoenix Road, and the site in Starcross Street is now closed.

The school and a large new building behind the school are a new “Euston Skills Centre”, set-up to provide training to local people and thereby providing the number of trained workers that such a large project requires.

The Euston Skills Centre was handed over to Camden Council on the 20th of November, however given that work within Camden has now been paused it will be interesting to see what Camden Council does with the facility. Hopefully there are still plenty of training opportunities for Camden locals to work on the project from Old Oak Common northwards.

Between the skills centre and Starcross Street is the second of the places where there has been a tangible change, compared to last year.

This is another temporary open space, in the form of Starcross Yard:

The theme for Starcross Yard is “echoes of place”, and within the space there are physical reminders of places from a surprisingly wide area, not just the HS2 construction site, or Euston.

To highlight these, there are information panels along the railings which tell of the “uncommon histories of people and space”.

The first is the Temperance Hospital, which was demolished as part of the clearance of the HS2 construction site:

The second covers the St. James’s Burial Ground, which again was cleared as part of HS2 site clearances. The panel highlights the boxer Bill Richmond who was buried at St. James’s Burial Ground, and a number of others buried are also named, as well as many from the workhouse:

Railings from the old burial ground now form part of Starcross Yard.

The above two panels refer to places that have become part of the HS2 construction site. The rest of the panels cover people and places that are further away, and not part of HS2.

The first of these is the German Gymnasium which today can be found by the southern entrance to Pancras Square, between St. Pancras and King’s Cross Stations:

Poles from the German Gymnasium can now be found at Starcross Yard.

Next up is Cumberland Market:

Cumberland Market was a short distance to the west of Euston Station, at the southern end of the Regents Park Basin, a small dock area off the Regents Canal.

My father grew up next to the Regents Park Basin, and I wrote about the area in this post. Starcross Yard has cobbles from Cumberland Market.

Next is St. Aloysius, a Somers Town Catholic Church:

The church is still functioning, although a mid 1960s rebuild, rather than the buildings shown on the panel. The church can be found to the east of Euston station, in Eversholt Street.

And the final panel covers the local schools, including the Maria Fidelis school, which is the large brick building beside Starcross Yard:

I rather like what they have done with Starcross Yard. Too often when large areas of London are redeveloped, there is nothing left to indicate anything about the people and places that once had a connection to the place.

Starcross Yard is temporary, and I hope whatever comes next retains this approach to the areas history.

Meanwhile, at the end of Starcross Street, the Exmouth Arms are still open:

Next to the Exmouth Arms is another of the site entrances, guarded by a rather bored security person:

At the end of Starcross Street is Cobourg Street, although the road element of the street is now boarded off, with only the footpath remaining.

Cobourg Street crosses Drummond Street, and last year you could walk along this far stretch of Cobourg Street, but during my 2023 visit, the footpath was being fenced off:

It seems to be a result of the “pause” in work of HS2 into Euston, that the whole site seems to be getting more enclosed and secure. I assume if you have a large area of open land sitting idle, you do not want the risk of anyone getting in.

This is the view back along Cobourg Street from Drummond Street towards the Exmouth Arms:

Where Drummond Street once ran all the way to the edge of Euston Station, it now stops at the junction with Cobourg Street, and continues on as a walkway, with the HS2 construction site on either side.

This is the view along the walkway, looking up towards Drummond Street:

And from the same location, looking towards Euston Station:

And back towards Drummond Street:

At the corner of where Drummond Street once met Melton Street is the original Euston station of the Charing Cross, Euston and Hampstead Railway (I wrote about a visit to the station and tunnels in this post):

To the left of the underground station is another large area of cleared space, this was the area once bounded by Melton Street, Drummond Street, Euston Street and Cobourg Street, and was where the Bree Louise pub was to be found:

The following view is from the same position as the above photo, and is looking along where Melton Street ran into Cardington Street. It was a short distance along Cardington Street that St. James’s Gardens could be found. The tree is the only reminder of the trees that once lined part of the street and across the gardens.

The view along what was Melton Street, with a walkway into Euston Station up the ramp to the left:

The walkway along what was Melton Street:

There is a small stub of Melton Street left, where it meets Euston Road, and again has a very quiet entrance to the HS2 construction site:

I then walked along Euston Road to find the third place where there is any tangible sign of a change. At the eastern side of the station is Eversholt Street, and in front of the station, and the bus stops, between Eversholt Street and Euston Road, one of the open spaces alongside Euston Road has been redeveloped:

The area is still secured by standard HS2 Euston green mesh fencing, but through it there appears to be a new taxi drop of point. It all looks finished, but no indication of when it will be opening:

Then a walk to the open space in front of the station:

With a view in the opposite direction showing the office blocks between Euston Station and Euston Road:

Returning to Melton Street, where there is a ramp leading to a walkway into Euston Station, this is the view, with a large open construction site behind the panels on the right:

If you walk into Euston Station, up to the first floor area where there is a pub and food outlets, at the western end of this space there are stairs back down to ground level, and from here there is a view over the construction space in front of the station, with Melton Street to the right, and taxi ranks alongside Euston Road:

Not much happening in this large area:

The station concourse:

That was the HS2 Euston construction site in 2023. Very little change compared to a year ago, with only two small gardens and a taxi drop off point the only external signs of change.

There were not that many construction workers around, and the perimeter of the site seems to be getting more secure, as if it is closing up for a long period.

HS2 seems to be a love / hate project, and whatever your individual views on the project, it does not give a good impression of the country when we seem unable to build major infrastructure projects such as HS2.

There is an interesting article on the London reconnections website, comparing the costs of infrastructure projects in the UK and other, comparable countries, and it is remarkable just how much extra, projects in this country are to build compared to others.

There are many complex reasons for this. Planning processes, funding complexity, objections to projects, long decision making, changes to decisions etc. all add to cost.

Although the Old Oak Common to Euston section has been paused, there will still be cost, at the very minimum the construction sites will need security, and I suspect it will take very many years before sufficient private finance is found to complete the project.

London Mayors and Government Ministers of all parties seem to like the phrase that “London is open for business”, a phrase which I find rather meaningless, but seems to translate as the city is open for anyone to purchase London’s assets, and this will probably be the way for Euston with offshore investment building up a new Nine Elms above a very slimmed down station.

Apart from the Silvertown Tunnel, HS2 is the only other major public transport infrastructure project in London.

Crossrail 2 has been “paused” since October 2020, and I doubt there will be anything for some decades to come.

Sorry to be so depressing on your Sunday morning.

I stayed taking a few more photos as it got dark, and as I left the station, the new information board in the outside concourse mirrored my thoughts at the time about the future of Euston’s development, with almost every train being delayed:

My visits to the Euston HS2 construction site for the past six years are covered in the following posts:

My first post was back in 2017 and covered St James Gardens, just before they were closed for excavation.

My second post in 2018 walked around the streets to the west of the station, as buildings began to close, and the extent of the works could be seen.

I then went back in 2019 as demolition started.

In 2020, demolition was well underway and St James Gardens had disappeared, and the associated archaeological excavation had finished

And in June 2021 I went back for another walk around the edge of the construction site.

Last year’s 2022 walk around the site is here.

I suspect the site will be much the same when I visit again later in 2024.

The Impact of the M25

13 Replies

The Impact of the M25 was the title of a 1982 report from the Standing Conference on London and South East Regional Planning.

I am sure that drivers have long had a love / hate relationship with the M25. When it is flowing well, it is a fast and efficient way around London, to reach different entry points to the city, or main roads and motorways spreading away from the city. At other times, it can be a car park, with a lane closure or accident quickly leading to miles of slow moving and stationary traffic.

The M25 is the latest in a series of attempts at moving traffic around the city. From plans in the 1940s by the City of London to circle the City with dual carriageways that became Upper and Lower Thames Street and London Wall, to the north and south circular, to the M25.

There is also a perception that London begins at the M25, and indeed with the recent expansion of the ULEZ zone, in some places such as near Waltham Abbey to the north, the ULEZ zone is up against the M25, as it is in the east, where to the east of Upminster the zone crosses the M25 to cover a small area of land around North Ockenden.

The M25 is closer to the centre of London in the north and extends further away around the southern stretch of the motorway. The following map shows the M25 as a complete ring around London ( © OpenStreetMap contributors):

The M25 is only there because of London. It was built to provide a route around the city without having to travel through built up and congested areas, and to offer a way for lorries and cars traveling from, for example, the midlands to the channel port at Dover, a fast route between the motorways that spread out from London.

However the M25, as indeed with any new road, has an impact far beyond the original intentions of improving traffic flow.

It will result in developments that aim to take advantage of the new road, it will open up areas for regeneration, it will generate new levels of traffic, and it will have an impact on the natural environment of the places through which the road is built.

Investigating the potential impact of the M25 was the aim of the 1982 report, to see what impact on the south-east this major new infrastructure project would have in the years ahead.

At the time of the report, the M25 was under construction, and the following map shows the expected completion dates of individual sections of the motorway from 1982 to 1986:

For nearly all post-war planning, the car and lorry were central to transport planning. This had started in the 1930s, and planning for post-war reconstruction in the 1940s expected a significant increase in personal car ownership and use for both work and pleasure purposes.

The cost of car travel would also gradually reduce compared to other forms of transport, and the report included the following graph, which shows that between 1971 and 1981, the costs of London Transport bus fares (1) and underground fares (2) had risen far more than both average earnings (5) and motoring costs (6):

The report identified five major development implications that the M25 would result in:

warehousing serving national and regional markets, for which the areas around Dagenham, Dartford, Grays and Redbridge are likely to be attractive;
high-technology growth industries; which are likely to be attracted to towns just beyond the Green belt;
offices which do not require a central London location. Increased demand in Romford, Croydon, Orpington, Hounslow, Uxbridge and Barnet is envisaged;
hypermarket and superstore developments for which locations close to M25 junctions would be most attractive, but would also conflict with Green Belt policy;
discount shopping stores, for which locations on major cross London routes such as the North Circular Road are likely to be attractive.

Much of the route of the M25 was through Green Belt, and the use of land close to the new motorway, would result in planning problems, and increase the value of land where development was permitted.

The route of the M25 through the Green Belt is shown in the following map:

Although there were a few very small exceptions, the M25 did not pass through Grade 1 and 2 agricultural land, although the report identified large areas of the highest quality land in east Hertfordshire, Essex, and north-west Kent, as shown in the following map:

Being close to the M25 could result in development pressures to these areas of high grade agricultural land, and these, along with the Green Belt were considered landscape constraints on where additional development could take place, and where proposals for development would threaten the natural environment and the production of food.

As well as agricultural land, a trip around the M25 provides an insight into the underlying geology of the land surrounding London. From the heathlands as you exit the M25 onto the M3, the flat, open lands of Essex as you exit onto the A13 and A127, and the chalk hills around the south of the M25.

Green Belt and agricultural land added to the policy constraints for land development around the M25, with Areas of Outstanding Natural Beauty and Special Landscape Areas also needing to be considered. The scope of these are shown in the following map from the report:

As well as natural and agricultural areas that were protected, there were also what the report classified as “Damaged Landscapes” which was land that had, or was being used as mineral workings, refuse tips, sewage works, electricity transmission installations and industrial development.

The report identified that some of these damaged landscapes, such as gravel working could be used for other purpose, such as recreational uses, but cautioned that areas used for refuse tips, mineral workings and sewage works would require very expensive restoration works.

The report also included “landscape under threat” which included deteriorating agricultural and woodland, as well as under-used open land close to urban areas (it is interesting that land always needs to be “used” and cannot just be left).

The areas of land included in these two categories are shown in the following map:

I well remember some of these “damaged landscapes”. As a child, an outing to Kent required a drive through the Dartford Tunnel, (which was built before the M25). On the approach to the tunnel from Essex, there were chalk quarries and cement factories on either side of the road.

These places were always coated in a thick grey dust, and I found a couple of photos on the excellent Geograph site showing the cement industry in West Thurrock:

West Thurrock cement industry — **West Thurrock Cement Industry, 1974**

The nearby Dartford Tunnels (now the Dartford Crossing with the addition of the bridge), is a major part of the M25, although not being officially part of it as the crossing still carries the designation of A282.

The first Dartford Tunnel was planned in the 1930s, and construction work did start, but was soon halted by the outbreak of the Second World War.

Work recommenced in 1959, and the first tunnel opened four years later in 1963. This was a single tunnel with two carriageways to carry traffic in both directions under the river. Crossing through the tunnel required the payment of a toll.

Traffic through the tunnel increased significantly and a second tunnel was planned, a key upgrade given that the M25 was also bang planned.

Money to fund the project was in short supply in the early 1970s, however funding was granted from the European Economic Community, allowing construction of the second tunnel to start in 1974, opening to traffic in 1980, with one tunnel being used for traffic from north to south, and the other tunnel used for south to north traffic.

Entrance to one of the Dartford Tunnels:

Even the two tunnels were insufficient for the increasing volumes of traffic once the M25 had opened, and starting in the late 1980s, construction started on the Queen Elizabeth II bridge, which opened in 1991.

The bridge now takes traffic running from north to south, with the two tunnels carrying traffic from south to north.

View of the Queen Elizabeth II bridge from near the Swanscombe Peninsula:

A journey across the Dartford Crossing, whether through the tunnels or across the bridge has always attracted a toll, which was originally used to cover the costs of construction. Toll booths once collected payment, however there have now been replaced by automatic number plate recognition, and online payment.

I found some figures for the tolls dating from the financial year 2016 – 2017, when the crossing generated almost £205 million, with £92 million coming from fines for unpaid fees, with a further £42 million of unpaid fines being written off as being unenforceable.

The latest traffic figures from National Highways shows that the Dartford Crossing carries more than 180,000 on its busiest days, with the highest amount recorded of 206,713 vehicles, on the 20th of February 2018.

The report tried to identify areas where there were a major development commitment. This data was dependent on local authorities, who provided data from different time periods and different classifications of development, but the plan attempted to identify the main sites and types of proposed developments:

Taking one area as an example, to the east, around the river crossing, large circles are shown to north and south of the river for industry and warehousing, with no identification of any planned shopping developments (shown as a small triangle in the above map).

This would change very quickly, with the Lakeside Shopping Centre being built in an old chalk quarry in the second half of the 1980s, in West Thurrock on the north side of the river, and the Bluewater Shopping Centre being built in the second half of the 1990s, again in a former chalk quarry, on the south side of the river.

The M25 provided a wide catchment area for these two shopping centres.

The area around the Dartford Crossing continues to be developed. The old oil and coal fired Littlebrook Power Station complex on the south side of the river next to the Dartford Cross has been demolished in recent years, and the area is now subject to major redevelopment with large numbers of warehouses which take advantage of easy access to the M25.

The M25 has also helped with the expansion of passenger numbers to London’s main airports, with both the M25, and motorways radiating out such as the M23 and M1 opening up large catchment areas for Heathrow, Gatwick and Luton airports.

Whilst the M25 has helped these airports attract passengers, the M25 has caused problems with any possible expansion of Heathrow, with the motorway being in the way of a number of possible options for an additional runway.

At the time of the report, there was an inquiry into the proposal to site London’s third airport at Stansted, and the report was sure that the M25 would have a positive impact on the development of Stansted, but would lead to greater pressures for development in the surrounding areas.

The report identified that the impact of the M25 would be major development pressures on many areas bordering the M25, whether retail, such as at Lakeside and Bluewater, warehousing and offices and residential developments.

As well as providing a simplified route around London, and between the major routes heading out of, and into London, the report highlighted the expected significant time savings.

The diagram below shows expected time savings based on a 1980 GLC Department of Planning and Transportation paper:

As an example, the diagram shows an expected time saving of 25 minutes between Brentwood in Essex and Heathrow, making flights from the airport a much easier option for those living in Essex. It would be interesting to see if these time savings were still achievable.

The extent of the impact of the M25 is shown in the following map, The M25 is the dark line circling the city. The inner and outer lines show the area within 10 minutes of the M25:

The report mentions that 10 minutes was an arbitrary figure, but was chosen to illustrate just how much of the wider area surrounding London was within a very short time of travel to and from the motorway.

The overall view on Development Pressures and Opportunities was summarised in the following diagram:

The diagram highlighted that the impact of the M25 would result in development pressures to places such as Chelmsford in Essex, as well as places much closer to the M25.

These pressures were despite limited development opportunities in many areas, with the Greater London Development Plan identifying that there were “no preferred industrial locations” in outer north-west London.

There was one area where development was encouraged, and it was expected that the M25 would help with opening up the area and attracting developers. This was the area to the east of the City, starting in the Docklands and spanning both sides of the river out to Basildon on the north and Medway on the south side of the river, as shown in the following diagram:

It was hoped that this area to the east of the City would ease the development pressures in the area from Watford in the north, down to near Gatwick, with the arrows on either side of the motorway in the diagram both pointing away from the area in the west, to the Docklands / Basildon / Medway area in the east.

Following completion of the M25, use of the motorway has expanded rapidly.

The Department for Transport has a number of automatic traffic counters located around the M25, and on many other major routes.

I took one of the counters which is located just east of the Holmsdale Tunnel on the M25, just by Waltham Cross as an example, and on an average day in the year 2000, there were 108,038 vehicles of all types travelling on both sides of the M25.

In 2022, this had grown to 142,242, over a 31% increase in traffic, and the 2022 average was still slightly below the pre-pandemic 2019 average of 146,475.

The 2022 number consisted of 298 two wheeled motor vehicles, 54 buses and coaches, 86,334 cars and taxis, 35,561 light goods vehicles and 19,995 heavy goods vehicles.

Whether this rate of increase continues remains to be seen. If it does, the M25 will resemble a car park with long queues more frequently than it does now.

The M25 is the busiest motorway in the country, and carries a large percentage of the country’s road traffic. The Department for Transport also provide traffic volumes for the five busiest road sections in the UK motorway network. Four of these are on the M25:

The table shows that the section between the M3 and the M40, which includes the sections running west of Heathrow, is the busiest part of the M25, and has four out of the five most heavily used sections of motorway in the country.

The fourth most congested section in the country is a section of the M60, to the south west of Manchester.

The 1982 report identified many of the development pressures that the M25 would bring to the areas surrounding the new motorway. Almost 40 years after completion, the M25 is a key part of south east England’s transport infrastructure, and the volume of traffic using the motorway continues to increase.

The M25 did reduce traffic volumes on London’s roads, and roads of the surrounding towns and villages, as traffic now had a more direct route to travel around, into or out of the city, however I suspect that with the general increase in traffic volumes, any initial reduction has probably been replaced by an increase.

Whether this continues to increase, whether the transition to electric vehicles will result in a change to traffic volumes, whether changing working patterns will have an impact, and how the M25 will continue to impact the surrounding areas remains to be seen.

What is certain is that the M25 is another example of how London impacts a much wider area than the central city.

And for another example of the impact of London, if you travel south on the M25, look to the left a short distance along from Junction 17 (providing you are not driving), and you will see the large construction site for HS2, at the point where the tunnels start as the railway heads north under the Chilterns.

It will be interesting to see how HS2 is viewed in 40 years time – and whether it has finally reached Euston.

Euston Station and HS2 – A 2022 Update

20 Replies

For the past five years, I have written an annual post on the work around Euston to create the extension to the station for HS2, recording the area from before work started to some point in the future, when the new station will be operational.

My first post was back in 2017 and covered St James Gardens, just before they were closed for excavation.

My second post in 2018 walked around the streets to the west of the station, as buildings began to close, and the extent of the works could be seen.

I then went back in 2019 as demolition started.

In 2020, demolition was well underway and St James Gardens had disappeared, and the associated archaeological excavation had finished

And in June 2021 I went back for another walk around the edge of the construction site.

It has been on my list to revisit for a 2022 update, but it always seemed a lower priority to other places, and with the end of the year approaching, I really wanted to walk the edge of the site again. After a morning in Fitzrovia in early December, the afternoon left time to visit Euston.

It was a lovely sunny, but cold, December day. Whilst the clear sky was welcome, the resulting low sun produced deep shadows which do not work very well with photographing scenes in a built area, but it was my last chance for 2022.

The size of the construction site is remarkable. In front off, and to the west of Euston Station, along Hampstead Road, up to the point where the rail tracks from Euston cross under Hampstead Road. The construction site then extends west alongside the rail tracks.

There continues to be background rumblings about the cost of HS2 and that it should be cancelled. Walking around the Euston site demonstrates what has been put into the site so far, and the sheer size. If it was cancelled what would happen to the space – another place of random towers as with Vauxhall?

The name HS2 I suspect is part of the project’s problem. Whilst it will offer a faster journey, the main benefit seems to be the extra capacity released on the existing lines by moving fast trains to the HS2 route. This extra capacity allowing services to improve to the places along the route – assuming there is the money and political will to do so.

Whilst the scale of the project at Euston is remarkable, this is only the London terminus of the route. There is a considerable amount of work along the whole of the route, and if you have driven along the M25, just north of the M40 junction, the massive work site can be glimpsed where tunneling starts on the 10 mile tunnel under the Chilterns.

Back to Euston, and the following map shows the area where work is underway, which I have outlined in red. There are two circled places which I will come to later in the post(Map © OpenStreetMap contributors).

This year, I started in Euston Station:

Then headed outside to see the front of the station, here the western side:

And the eastern side of the station:

In the forecourt of the station, is a statue to one of those buried in the cemetery at St James Gardens. An area where the graves have been excavated and the gardens now part of the overall construction site. See the 2017 post for a walk through St James Gardens. The statue is of Matthew Flinders:

Matthew Flinders was born in Lincolnshire on the 16th of March 1774. He joined the Royal Navy and in the early years of the 19th century he mapped much of the coast of Australia, and was the first to demonstrate that Australia was one single continent.

His chart of Australia, or Terra Australis, was published in 1814. Although the name Australia had been in use, Flinders use of the name for his chart, was the first to apply the name to the overall land mass of the country.

He had a lengthy return to London, however after his return his health deteriorated rapidly, His life at sea had taken a considerable toll on him, and he died at the age of 40 on the 19th of July 1814.

A brief announcement of his death in the London Evening Mail gives a hint of the challenges he had faced: “On Tuesday last, Captain Matthew Flinders, of the Royal Navy, greatly lamented by his family and friends. This Gentleman’s fate has been as hard as it has been eventful. Under the direction of the Admiralty, he sailed in 1801, on a voyage of discovery to Terra Australis; where, after successfully prosecuting the purposes of his voyage, he had the misfortune to run upon a coral rock and lose his ship: out of the wreck he constructed a small vessel that carried him to Mauritius, where, shocking to relate, instead of being received with kindness, as is the practice of a civilised nation to nautical discoverers, he was put in prison by the Governor and confined for six years and a half, which brought upon him maladies that have hastened his death. Fortunately for mankind and his own name, he survived a few days for finishing of the printing of the account of his voyage.”

His account of the voyage was published on the 5th of December 1814 as two volumes and “one very large volume, folio of Charts, Headlands and Botanical subjects”.

He died in a street roughly where the BT Tower is today and was buried in the burial ground for the parish of St. James Piccadilly, which was in use between 1790 and 1853, and which became St James Gardens until becoming part of the Euston HS2 construction site.

Matthew Flinders grave was discovered during the excavations to recover the bodies buried in the gardens, and his remains are due to be reburied at St Mary and the Holy Rood church in Donington, the village of his birth.

The statue, by sculptor Mark Richards, was initially unveiled at Australia House in 2014, before being moved to the forecourt of Euston Station.

Office block at the eastern edge of the forecourt:

Directly in front of Euston Station is an open space, where the Flinders statue is located. There is then a row of office blocks, under which is a bus station:

And a pub, the Doric Arch, part of which can just be seen in the above photo, and the following photo is one I took a while ago, after dark;

The entrance to the pub, and toilets, occupy the ground floor, with the main pub on the first floor, which is surprisingly good, given its location and modern construction in the base of an office block. Despite the appearance in the above photo, it can also get very busy.

The Doric Arch was originally called the Head of Steam, but changed name to the arch that once stood in front of Euston Station when the pub was taken over by Fullers around 2008.

The Doric Arch is still run by Fullers, and according to the pub’s website, one of the stones from the original Euston Arch after which the pub is named, is on display behind the bar. I have no idea how I have missed this, but it is a good excuse for a return visit.

The pub sign is now an image of the Euston arch:

Buses queue to leave their stops, underneath the office block in front of Euston Station:

In front of the office block is the London and North Western Railway War Memorial. Designed by the railways’ architect, Reginald Wynn Owen, to commemorate the railway company’s workers who died in the first world war:

The following photo shows the memorial in the same position, prior to the demolition of the original Euston Station and hotel:

On the right of the above photo is one of the gatehouses that are still on either side of the entrance to Euston Station. The gatehouse can still be seen today, although the gardens that were behind the gatehouse, running alongside Euston Road, are now fenced off and are part of the considerable area of works surrounding the station.

Walking to the west of the station, and this is the view along Melton Street, which is now closed off, apart from being a construction site access gate:

To the right of the above photo is the taxi drop off and pick up point for Euston Station:

There is still a walking route to the west of the station, along Melton Street, however this is lined by hoardings on either side:

The western walking route into the station:

Continuing on along Melton Street, with the station on the right:

Another construction access gate:

Where on the corner of what was Melton Street and Drummond Street is the original Euston station of the Charing Cross, Euston and Hampstead Railway. The station is one of Leslie Green’s distinctive station designs, and whilst all the buildings surrounding the station have been demolished, it still survives, probably due to all the infrastructure within and below the station (I visited the tunnels below in this post):

From alongside the station, we can look down what was Cardington Street. It was along here on the left that St James Gardens were located:

To exit the overall Euston site, the walker heads west through a corridor lined with hoardings (a theme of the entire site), towards Drummond Street:

Looking back, and the route is signposted to Euston Station:

A glimpse between the hoardings shows the size of the construction site running north from Euston Station:

This is the view to what was the corner of Cobourg Street and Euston Street. The Bree Louise pub was just on the left of the photo:

Looking north along Cobourg Street which is now fenced off, apart from the footpath to the left:

At the end of Cobourg Street is another gate to the main construction site:

And on the corner of Cobourg Street and Starcross Street, the Exmouth Arms is still there, and still open (small circle in the map at the start of the post):

Just behind, and to the west of the Exmouth Arms is a new building:

At the end of Starcross Street are these school buildings (large circle in the map at the start of the post):

The buildings were home to the Maria Fidelis School.

To free up the school site, HS2 have built a new school between Drummond Crescent and Phoenix Road, and the site in Starcross Street is now closed.

HS2’s plans for the school, also reveal the use of the new building between the school and the Exmouth Arms. From the HS2 website, the school and new building will “include welfare accommodation for HS2 site and management staff, and a Construction Skills Centre, including training rooms, workshops and interview rooms”.

The following view is the best I could get of the front of the old Maria Fidelis School, which shows a typical early 20th century brick school, with central curved section, and the playground area on the roof which is surrounded by metal fencing:

We have now reached the Hampstead Road, and the following view is looking north. Hoardings continue to screen off the construction site, and as well as the standard information panels, they are covered in site and health and safety information:

Looking down what was the northern end of Cardington Street, where it joined Hampstead Road:

Where to the right of the above photo there is a large temporary office complex:

Looking north from the old junction with Cardington Street, and construction works continue on both sides of the street. To give an idea of how far these works run, Mornington Crescent underground station is not that far after the tower blocks in the photo:

This is looking across Hampstead Road to where construction continues heading west, parallel to the existing railway tracks that run into and out off Euston Station.

Where there is another access gate:

The photo above and the photo below give an indication of the scale of HS2 construction works around Euston. In the above photo, work s continue for some distance from Hampstead Road west, parallel to the existing rail tracks.

At some point, a new bridge will be needed to take Hampstead Road across the extra railway tracks into Euston Station.

The works heading west of Hampstead Road in the above photos lead to the wonderfully named “Euston Cavern”, which is described in the HS2 Euston Approaches FAQ as “a very large, underground structure at the Parkway end of the worksite, to enable one tunnel to split into two, so that trains can access the tunnels from the necessary range of platforms at Euston”. This tunnel takes the tracks away from Euston and heads towards a new station at Old Oak Common.

In the photo below, I am looking south along Hampstead Road, with the hoardings fencing off the construction site disappearing into the distance. Although it cannot be seen, Euston Station is to the left, some considerable distance across the construction site.

The HS2 construction works around Euston are considerable, and construction on the line is continuing all the way to Birmingham.

My last walk round the site was in June 2021, eighteen months ago. From alongside the construction site, not too much appears to have changed. The fenced off area has expanded slightly, but looking in from the outside, it is still a massive ground level construction site.

According to the HS2 website, phase one of the route from Euston to Birmingham is scheduled to open between 2029 and 2033 – it will be fascinating to have watched the site evolve from the original streets, gardens and pubs to the latest iteration of Euston Station.

London to Portsmouth Semaphore – Chatley Heath

12 Replies

A couple of weeks ago I wrote about the route that the body of Eleanor of Castile took to reach London, and the crosses that were built to mark the route. For today’s post I am tracing another of the historic routes that link London with the rest of the country.

Back in the 18th century, the speed of communication was mainly dependent on how long it took a horse and rider to travel between the source and destination of a message. Routine mail would be carried by stage coach and urgent messages would travel via a horse and rider who could travel much faster, but would still be limited by the speed of the horse, conditions of the roads, weather need to change and rest horses etc.

In 1770, the average time taken between London and Portsmouth was around 17 hours, but with improvements to road surfaces and coach building, by around 1820 this had improved to 9 hours for the fastest coaches.

The very best horse and rider could cover the route in just under 5 hours.

It seems remarkable when today we can make an instantaneous mobile phone call from almost anywhere in the country to the other side of the world, that just two hundred years ago it would take a day to get a message and answer between London and Portsmouth.

Portsmouth was important as it was the site of a major naval dockyard, and with the frequent wars of the late 18th and early 19th centuries there was need to devise a system which could rapidly send messages between the Admiralty in London, and the naval dockyards.

The Napoleonic Wars of the later 18th century resulted in the Admiralty building a telegraph system that copied a system already set up by the French. This used a method where signaling stations were based at high points along the route between London and Portsmouth. At each station, there was a wooden shed with a shutter frame built above. The frame held six shutters in two columns, and each shutter could be opened or closed to send a message to the next station along the route.

It was claimed that a message could be sent between London and Portsmouth in just under 8 minutes.

At the end of the Napoleonic Wars the system was dismantled, with Napoleon being held on the Isle of Elba.

Not long after, Napoleon escaped and returned to France, and the state of war between England and France resumed. The Admiralty needed another, and more permanent line of communication between London and Portsmouth, rather than the temporary wooden sheds set up for the shutter system.

The Admiralty created a new signaling line comprised of stations using a semaphore system, where the positions of two moveable arms would signify a message to be sent along the chain.

The following print shows the Admiralty building in Whitehall. On the roof at the rear of the building, a tall post can be seen with two arms. This was the London end of the chain of stations between London and Portsmouth (© The Trustees of the British Museum).

Signaling stations were needed at high points on the route between London and Portsmouth. Each station was equipped with a post and signaling arms, and had an observer with a telescope to keep an eye on the adjacent stations in the chain for any message that needed to be sent onwards.

The following map shows the chain of stations from the Admiralty at top right down to the dockyard in Portsmouth at lower left (© OpenStreetMap contributors):

The system was opened two hundred years ago, in 1822, and an article in Bell’s Weekly Messenger in September 1822 listed the stations as;

The Admiralty, Chelsea, Putney Heath, Kingston Hill, Cooper’s Hill, Chatley Hill, Pewley Hill, Bannicle Hill, Haste Hill, Holner Hill, Beacon Hill, Compton Down, Portsdown, Lumps Fort (Southsea) and Portsmouth naval dockyard.

In 1822 it was claimed that a message could be conveyed between the Admiralty in London to Portsmouth in one minute and a few seconds. This seems remarkable and must have been in ideal conditions, perfect visibility, and the staff at the stations were ready for the receipt and forwarding of a very short message. Reports of normal transmission times state that around 15 minutes was the time taken to send a message from one end of the chain to the other – still a remarkably short time.

There is one remaining, complete, semaphore tower on the line between London and Portsmouth, at Chatley Heath in Surrey. Indeed it is the only remaining complete semaphore tower in the country. It has recently been restored by the Landmark Trust who held an open day in the summer. so I went along to see this remaining example of two hundred year old communications technology that linked London with the south coast.

In the above map of the whole chain of stations, I have marked Chatley Heath with a red circle around the red dot.

The following map shows the exact location of the Chatley Heath semaphore tower, a very short distance from the M25 and slightly to the east of the A3 (© OpenStreetMap contributors):

Chatley Heath is part of a wider area of 800 acres of commons and rare heathland that is managed by the Surrey Wildlife Trust. There are paths across the heath, some of which are signposted to show the route to the semaphore tower:

The open day was on one of the hot days of summer, where the land was so dry following weeks with no rain, a big contrast as I type this, as it is cold, cloudy and there has been much rain over the last few weeks.

Following the path to the semaphore tower:

The following photo shows the first glimpse of the semaphore arms at the very top of the tower, just showing above the tree line in the distance in the centre of the photo:

Finally reaching the Chatley Heath semaphore tower. The one remaining, fully restored tower, and the tallest on the line between the Admiralty in London, and Portsmouth.

Each semaphore station was manned by a retired navy lieutenant and an observer, usually a retired sailor of the lieutenants choosing. The lieutenant would be in charge of the station, and the observer was responsible for using a telescope to keep an eye on adjacent stations to check for messages to be forwarded.

The very first officer at the Chatley Heath tower when it opened in 1822 was Lieutenant Edward Harris.

The Chatley Heath tower included accommodation with a small house built onto the base of the tower. The blocked up windows in the tower were probably done to save the cost of building and installing windows. The navy was exempt from window tax, so this would not have been the reason. The shape of the tower was also more cost effective than the complexity of building a circular tower.

The semaphore system used a code devised by Rear Admiral Sir Home Riggs Popham.

It was Popham who created the code using flags, allowing messages to be sent between ships at sea, and it was his code that sent the message from Nelson at the Battle of Trafalgar that “England expects that every man will do his duty”. He was involved in a number of naval actions, and assaults on enemy land forces across the world, but must have spent some time at home as his wife had at least ten children.

Popham’s semaphore code used two arms on a wooden post. Each arm could assume any position on either side of the post, so could be either horizontal, vertical, or at an angle of 45 degrees, pointing up or down the post.

This arrangement created enough positions using the two arms that every letter of the alphabet, along with the numbers 0 to 9, could all be transmitted.

The two arms and vertical post:

From 1963 until 1988 the tower was left empty. It was vandalised and had suffered a major fire. It was restored in 1988 by Surrey County Council and then passed to the Surrey Wildlife Trust.

The age and very exposed position of the tower resulted in further, gradual deterioration, with water being a problem, getting into the tower around the base of the post, and around the windows.

The Landmark Trust then took on the tower and commenced a full restoration project in 2020. The Landmark Trust has restored and runs some remarkable buildings across the country, and following a restoration, they rent out the buildings for short stays, and this is now the future of the Chatley Heath semaphore tower.

The restoration including fitting out the tower so that it would include accommodation, so today, walking up the tower to the roof includes a walk through a number of rooms, which include a lounge:

Kitchen:

And bedroom:

There is a second bedroom (the tower now sleeps 4) and a bathroom.

In the kitchen, the restored mechanism used to control the position of the arms can be seen:

Once on the roof, it is easy to see why this was the chosen location for the station. It is one of the highest points in the local area at 59 meters above sea level, with the land dropping by 10 to 20 meters in the area surrounding the station.

This is the view looking towards London:

Zooming in from the roof of the tower, we can see the towers of London in the far distance, the Shard to the right is just over 31km from the Chatley Heath semaphore tower.

The semaphore post and arms seen from the top of the tower:

Operating the semaphore was not without its dangers. The Hampshire and Southampton County Newspaper reported on the 15th of August 1825 that: “During the thunder storm on Wednesday last, E. Oke, the signal man belonging to the semaphore in Portsmouth, was knocked down and remained insensible for several minutes. The semaphore was at work at the time, and the man had his hand on the wheel, which turns the arms to communicate intelligence to the next station. The whole apparatus is composed of metal, which, of course, attracted the lightning. The Lieutenant, who was standing close by, did not experience the slightest inconvenience, neither was any serious injury sustained by the man or the buildings”.

View looking towards the south, the next station at Pewley Hill was somewhere in the distance:

Chatley Heath was to be the branching point for another chain of semaphore stations, which would have run all the way to Plymouth, however this chain was only completed a short distance after Winchester.

The London to Portsmouth semaphore system ran from 1822 until 1847 when it was made redundant by the coming of the railways and the electric telegraph. The London & South Western Railway connected London to the south coast at Southampton, Gosport and Portsmouth and the new electric telegraph was laid alongside the railway. This provided a far more reliable and cost effective means of sending messages between the Admiralty and the naval dockyard at Portsmouth.

The semaphore line was closed at the end of 1847, and the staff made redundant, which must have been a blow to them as the staff were usually at the end of their naval careers and other opportunities for employment would have been limited.

The views from the tops of the semaphore tower show what a high location this is relative to the surrounding land. As well as the towers of the city shown in an earlier photo, from the top of the tower we can just about see the arch over the Wembley stadium in the distance:

The location of the semaphore stations can often be found in local naming, with Telegraph Hill being used at a couple of the old station locations. there is a Telegraph pub in Putney named after the original shutter telegraph on Putney Heath. There are a number of Telegraph Roads and Telegraph Houses along the route.

The London to Portsmouth semaphore / telegraph route was one of many that were built during the early decades of the 19th century. The admiralty built a number of chains to enable communication with key dockyards.

There were also commercial telegraph chains set-up. One, by a Lieutenant Watson was created between Holyhead and Liverpool and reported the names of ships passing Holyhead on their way to the docks at Liverpool. This would enable ship owners to have advance information of when their ships would be arriving in port.

Lieutenant Watson devised his own code for the telegraph system. He may have also been responsible for creating another system from London to the coast. The following print shows Watson’s Telegraph, near Tooley Street (© The Trustees of the British Museum).

This has a similar arrangement to the semaphore route between London and Portsmouth, however it uses two rather than one post, and it appears that one of the posts had two arms at the top. Presumably this arrangement was to allow more complex messages to be sent at a faster rate.

The Chatley Heath semaphore tower is a wonderful reminder of a time, only 200 years ago, when it took hours to send a message the distance from London to Portsmouth, and the technological change that started to speed up communication.

Campden Hill Water Tower, an Observatory and Sir James South

15 Replies

Before heading to Campden Hill, a quick reminder that if you are interested in discovering the history of the New River, New River Head, the Oak Room and Devil’s Conduit, there are a few tickets remaining for a walk by Islington Guides starting this coming week. I will be guiding on a couple of these walks and they can be booked at this link.

For this week’s post, I am in the area between Kensington Gardens and Holland Park, in Campden Hill Road, looking up the street towards the now demolished water tower as seen in this photo by my father, and dating from 1951:

The same view in August 2022:

The view nearest the camera has hardly changed. The buildings on either side of Campden Hill Road are the same. What has changed is the view in the distance where the water tower once stood is now a development of flats.

The Campden Hill water tower was built as part of the 19th century roll out of water supplies across an expanding London.

The Grand Junction Water Works Company purchased the land at the top of the road in 1843, and built a reservoir. This was followed by a pumping station and the water tower. (I have also read reports that the water works opened in the 1820s on land purchased from the Dowager Marchioness of Lansdowne, and that the water tower was built in 1847).

The water tower is unusual in that it did not hold a water tank. Instead, large pipes ran up the tower, and these would hold water, with the height of the pipes adding to the pressure of water supplied from the location.

I have shown the location of the water tower, and the associated water supply infrastructure, within the red rectangle in the following map:

The map shows that the water tower was just over half way up Campden Hill Road, but we need to look at another type of map to understand why it was located at this point in Campden Hill Road.

The following map (from the excellent topographic-map.com) shows land height as different colours, with blue as the lowest height, up through green, orange, red and pink as the highest. I have placed a black star symbol at the location of the water tower, and as can be seen by the surrounding colours, this is the highest point in the area, and the natural height of the land would have given a pressure advantage to water from the site, to which the water tower would have added.

The name of the road – Campden Hill Road – also highlights that the road runs both up and down a hill. Next to the original location of the water tower, we can see the road descending in both directions. Looking north:

And looking south:

There was a local myth that involved the height of the land where the water tower was located. Almost opposite the location of the water tower is a pub called the Windsor Castle, and the myth was that before the water tower was built, a keen eyed observer could see the real Windsor Castle from this high point, hence the name of the local pub.

This myth was certainly still going into the 1950s when a letter in the Kensington Post disputed that you could have seen the castle from this point, and it was even doubtful that you could see the castle from the top of the tower.

This source of the name is not mentioned on the pub’s website, which does though claim the 1820s as the age of the pub, so it does pre-date the water tower.

The water tower and associated infrastructure became part of the Metropolitan Water Board in 1904 when the MWB took over the assets of the many water companies operating in London, and brought these under the control of a single, London wide, water supplier.

The water tower was last used for the storage of water within it’s pipe in 1943, and was then redundant for a number of years. Plans to demolish the tower started in the early 1050s and in the 28th of March 1952 edition of the Kensington News and West London Times, there was an article with the headline “Goodbye to the Great Grey Tower”. The newspaper had asked local residents how they felt about the loss of the tower and reported that their general reply was that they would “Miss it dreadfully”.

The tower would though remain for many years, and during the 1960s it was leased to Associated Rediffusion who had equipment to relay television signals mounted on the tower.

There were a number of proposals for what would replace the tower throughout the 1960s, many reported in the Kensington Post, who also sent a photographer to take some photos of the view from the top of the tower.

It would finally be demolished in the first months of 1970, and the site of the water tower and associated works is now occupied by the housing seen in the following photo:

As well as being part of London’s water supply, and a local landmark, the Campden Hill water tower is also unique as it is (as far as I know) the only water tower to feature in, and on the cover of a work of literature:

The Napoleon of Notting Hill by G.K. Chesteron is a rather unusual book. Published in 1904, it tells of the story an alternative reality, where the country is ruled over by a randomly selected head of state, one Auberon Quinn who had been a clerk. Quinn decides to turn London into a form of medieval city. One man, Adam Wayne, takes this very seriously, and uses it as a means to support local pride. Wayne even went to the length of setting up a Notting Hill army to fight invaders from other neighbourhoods – hence the title of the Napoleon of Notting Hill.

Theoretically set in a London of the future, the book describes technology and the city as it was when the book was written.

The water tower features many times in the book, including in Chapter Three —The Great Army of South Kensington, where the various forces of different streets and local areas assemble and where battle takes place, for example:

“Morning winked a little wearily at me over the curt edge of Campden Hill and its houses with their sharp shadows. Under the abrupt black cardboard of the outline, it took some little time to detect colours; but at length I saw a brownish yellow shifting in the obscurity, and I knew that it was the guard of Swindon’s West Kensington army. They are being held as a reserve, and lining the whole ridge above the Bayswater Road. Their camp and their main force is under the great Waterworks Tower on Campden Hill.”

and:

“In the event of your surrendering your arms and dispersing under the superintendence of our forces, these local rights of yours shall be carefully observed. In the event of your not doing so, the Lord High Provost of Notting Hill desires to announce that he has just captured the Waterworks Tower, just above you, on Campden Hill, and that within ten minutes from now, that is, on the reception through me of your refusal, he will open the great reservoir and flood the whole valley where you stand in thirty feet of water. God save King Auberon!”

The reason why Chesterton set his book in the area, and uses the water tower as a key feature must be that he was born in Campden Hill on the 29th of May, 1874, so he knew the area very well, and the water tower would have been a very familiar feature.

The Napoleon of Notting Hill is a really strange book, but good to have the Campden Hill water tower recorded in a work of literature.

Walking south, down the hill from the location of the water tower is this terrace of large residential buildings:

One of which has a blue plaque recording that the photographer Bill Brandt lived here:

I felt rather guilty taking the photo of Bill Brandt’s plaque on a modern digital camera, when I should have been using my father’s old Leica film camera.

Brandt was a master of film photography. Born in Germany in 1904, he moved to London in 1933, and would spend the rest of his life in the city until his death in 1983.

I have no idea when, and for how long he lived in Campden Hill Road, however a number of his photographs were taken inside the building, many of which date around the 1940s, so he was there for some of that decade.

Brandt took a series of photos of London during the war, and his photos of the Underground being used as air raid shelters have become representative of that period in London’s history. Many of his wartime photos of London are in the collection of the Imperial War Museum:

Christ Church, Spitalfields: Man sleeping in a stone sarcophagus in Christ Church:

Continuing on down Campden Hill Road, and the area around the road is full of interesting architecture and plenty of history and interesting characters. I cannot cover everything I would like to in the space of a weekly post, so I will pick one small street which has plenty of interesting stories to tell.

In the map below, I have put a blue oval around Observatory Gardens, a small street that leads from Campden Hill Road to Hornton Street:

I will come on to the origin of the name Observatory Gardens, however lets have a look at the buildings first.

Along the northern side of Observatory Gardens is a continuous terrace of brick houses with white painted detailing.

By 1870, the land now occupied by Observatory Gardens had been purchased by Thomas Cawley, a local south Kensington builder. He subcontracted the construction of the street, however his subcontractors went bankrupt, so Cawley completed the work himself, and the street was finished in 1883.

The street suffered some severe damage during the last war when a German bomber crashed into Campden Hill Road, having taken off a large roof in Observatory Gardens, and the crater in the street causing additional damage. A report in the West London Observer on Friday the 18th of April 1941 tells the story:

“London experienced one of the heaviest raids of the War during Wednesday night and early Thursday morning and numerous heavy, high-explosive missiles as well as thousands of incendiary bombs were dropped. Damage was on a large scale and many people were killed.

The German radio yesterday (Thursday) declared that the raid was the heaviest ever on London and the biggest raid of the War, and that 100,000 fire bombs were showered down.

On Thursday morning thousand of Londoners made their way to work over hose-pipes and broken glass, while firemen, begrimed and exhausted, still dealt with the smoldering ruins. Many had to make extensive detours to reach their place of business and thousands found their offices and shops bombed out when they got there.

Altogether five Nazi planes were brought down, one of which crashed in Campden Hill Road, a turning off Kensington High street. Actually the plane hit the roof of a large house in Observatory Gardens before crashing into the roadway about 50-feet away. Bombs from the plane must have crashed into the road in front of this house as there is a very large crater.

The German plane finally came to rest by the side of a large Hostel, part of the University of London.

At the controls was a dead pilot. No traces of other members of the crew could be found, so it is assumed that they had jumped. Later the bodies of two Nazi airmen were discovered in the locality, badly mutilated.

Residents at Campden Hill Road heard the whistle of the approaching aircraft before it crashed. There was no engine noise. Wardens say that it was not on fire.

The bomber touched chimney pots and then disintegrated in small pieces. Its heavier parts, one of the engines and two propellers, landed on the top of a block of flats where some Maltese evacuees were billeted.

An oil tank burst at the same time, and two rooms of the top floors of the flats, which were being used for bedding and linen, caught fire.

During the day, thousands of people passed the spot to see the scattered remains of the bomber. By the afternoon there was little to see as army lorries had conveyed the debris to one of the various scrap bases set aside for this purpose.”

Observatory Gardens was left badly damaged by the crash of the bomber, and as with so many streets across London, the street would not recover for a couple of decades.

In the years after the war, Observatory Gardens became very run down, and it was not until the 1990s that the street we see today emerged. Whilst the exterior of the buildings were restored, much of the interior of the buildings appears to have been considerably rebuilt.

Before Thomas Cawley purchased the land and developed Observatory Gardens, the land was owned by Sir James South, a fascinating character who made astronomical discoveries and also appears to have spent a fair amount of time in the courts.

Sir James South purchased a house and land in 1827 from the Phillimore family, and set about building an astronomical observatory in the grounds.

He started a career as a surgeon in Southwark, and there established an observatory in Blackman Street. He worked with the astronomer John Herschel on the observation of double stars, but he was often difficult to work with, and was frequently drunk.

Despite this, he became President of the Astronomical Society in 1829, but after arguments with a number of Fellows, his involvement with what would become the Royal Astronomical Society faded.

He continued his observations from his house on the land that is now Observatory Gardens, and got involved in a number of disputes with the council who were proposing to extend Camden Hill Road. He believed that the vibrations from traffic on the extended road would impact his telescopes and his observations.

His legal disputes were not just about issues that threatened his observations, he would take legal action on many issues that he daily encountered. One was in 1855 when he took a conductor of a Paddington omnibus to court for deceiving him.

South had apparently hailed the omnibus near King’s Cross and had asked the conductor if it was the Royal Oak omnibus. The conductor confirmed that it was, so South boarded.

The bus continued to Chapel Street by when all the passengers had left the bus, with the exception of South. The conductor stated that the bus would not be going any further than the next stop, and South got into an argument with the conductor regarding the destination of the bus, and that the conductor had informed South that it would go to Royal Oak.

At court, the conductor denied that he had told South the omnibus was going to Royal Oak, stated that South had got on the bus without speaking. Despite this, the court sided with Sir James South and convicted the conductor with a penalty of 20 shillings plus costs.

Whatever the truth of the matter, the case of Sir James South and the conductor of an Omnibus shows that South would take an issue to court no matter how trivial it was, and with the unequal resources and reputation of an omnibus conductor and Sir James South.

Sir James South:

The Illustrated Times published an obituary for Sir James South on the 26th October, 1867:

“We have to announce the death of Sir James South, F.R.S. at an advanced age. He was the son of a dispensing druggist, who towards the close of the last century carried on in business in Blackman-street, Borough; but James South entered upon a higher branch of the medical profession, and became a member of the Royal College of Surgeons. For some years he practiced his profession in Southwark, and in the intervals in business pursued the study of astronomy, in connection with which he made some extremely valuable observations. In 1822 and 1823, in conjunction with Sir John Herschel, he compiled a catalogue of 380 double stars.

After this he removed to Campden-hill, Kensington, where he constructed an observatory, to which he devoted the closest attention during the remainder of his life, and which has achieved European fame. He was one of the founders of the Royal Astronomical Society, and was for a time its president. In 1830, on the recommendation of the Duke of Wellington, who was then prime Minister, he received the honour of knighthood, and for several years past he has enjoyed a pension of £300 a year on the Civil List for his contributions to astronomical science.

The account of Sir James South’s astronomical observations during his residence in Southwark is published in the Philosophical Transactions for 1825, and is accompanied by a description of the 5 foot and 7 foot equatorials with which they were made. one of these instruments is still mounted and in excellent condition at the Campden-hill Observatory. There are also in the observatory a 7 foot transit instrument, and a 4 foot transit circle. Sir James South was born in 1785.”

The street name Observatory Gardens is therefore named after Sir James South’s observatory that once occupied the land. The following photos shows the end of Observatory Gardens, where the street meets Hornton Street:

One of the newspaper reports I read about the water tower is that the arrival of the Grand Junction Water Works Company, and the resulting reliable supply of water, was one of the reasons why the area developed rapidly during the first half of the 19th century, and that much of that development was of large, ornate, houses.

At the eastern end of Observatory Gardens is Hornton Street, and this is the view looking north – of many of those large, ornate, houses:

And the view looking south, as the hill which gave the area its name continues to descend towards Kensington High Street. Lots more red brick and white decoration:

One thing I realised as I get towards the end of the post is that I have not explained the origin of the name Campden Hill. The Hill element obviously comes from the hill on which the area is built, and that resulted in the water tower being built here. Campden came from Campden House, a large house that was built here by Baptist Hicks, 1st Viscount Campden in the 17th century. The Camden in his title came from Chipping Campden in the County of Gloucester.

In the 19th century and much of the 20th century, there was a considerable amount of infrastructure supporting the provision of water, gas and electricity across London. As with the Campden Hill water tower, so much of this has disappeared, as the technologies used to distribute these services has changed.

Campden Hill is a fascinating area to explore, and I hope this post has provided an indication of what can be discovered across some of the streets.

New River Walk – Alexandra Palace to New River Head

12 Replies

I have finally completed the post covering the last stage of the New River Walk, which covers from Alexandra Palace to New River Head in north Clerkenwell.

At the end of the previous stage, we had reached Bowes Park, where the New River disappeared in a tunnel, and for today’s post, we rejoin the New River where it exits the tunnel, opposite Alexandra Palace station.

This stage of the walk will follow the New River from Alexandra Palace to the east and west reservoirs, just south of the Seven Sisters Road, where it ends as a river. Then, the walk follows a Heritage Walk that follows the original route of the river to New River Head before the river was truncated at the reservoirs.

The map of the final stage, with key locations covered in the post is shown below (© OpenStreetMap contributors):

New River Walk Alexandra Palace to New River Head

Point S on the map: Alexandra Palace station is at the north west tip of a patch of open, green space, and at the south east corner of this space, the New River exits the tunnel through which it has flowed from Bowes Park:

There is nothing to see of the actual river between Bowes Park and Alexandra Palace, however there are a number of these New River Company pipe markers:

Point 1 on the map: Here, a rather over exposed Alexandra Palace can be seen on the high ground in the distance. Hornsey Water Treatment Works are behind the green metal fencing and the New River runs under the footbridge between the fencing:

The route through Hornsey is an example of where the New River has been straightened and does not follow the original early 17th century route.

The following map from 1861 shows the original early 17th century route (dark blue), along with the proposed new straightened route (light blue):

Hornsey Water Treatment Works are to the left, and the New River runs at the bottom of these works, and heads to Hornsey High Street which it crosses, before turning and crossing Middle Lane. It then heads towards the church and crosses the High Street again, heading up to the junction with Tottenham Lane.

Towards the top of the map, the Great Northern Railway runs from left to right, and below the railway can be seen the proposed new route of the New River, which is straight, and cuts of the large loop around Hornsey.

Roughly the same area as the above map, is shown in the following map of the area today, which includes the new route of the river just below the railway, and streets and buildings now covering the original route of the river around Hornsey (© OpenStreetMap contributors):

There are a number of similar examples on the New River Walk where the route follows where the river has been straightened rather than the original route. It would be an interesting exercise to follow the early 17th century route, however I think I will put that walk on the long list of London walks.

Point 2 on the map: There were very few places on the entire route where it was not possible to follow the New River walk, however one place on this final stretch was also in Hornsey where the path had been closed off as Thames Water are carrying out some repair works on the river:

Following photo is looking along the closed section of the walk. This is another straightened section of the New River:

Point 3 on the map: The New River then runs through a housing estate which was built around the New River. The following map extract shows the river running between terrace housing and under streets. There is no path alongside this section of the river, and walking to where the river crosses each street, then back, would add a considerable distance to the walk, so the Thames Water New River path runs along Wightman Road to the left (© OpenStreetMap contributors):

The view looking down one of the streets from Wightman Road, the New River crosses the street half way down:

In the above photo, the streets is dropping in height towards the point where the river crosses about half way down. This stretch of the New River demonstrates how the river follows the contours of the land, from the source in Ware to New River Head. A considerable distance which needed some careful planning, and is remarkable given the survey technologies available in the early 17th century.

The following map shows land height by colour, with blue being lower land, then increasing in height through green, yellow and red (from the excellent topographic-map.com):

I have marked the route of the New River which is following the boundary between the higher land on the left (around Crouch Hill station), and the lower land on the right (south Tottenham and Seven Sisters station).

At one point in the map, an area of higher ground (yellow) juts out, and the New River has been tunneled under this, before emerging and running through the streets to the east of Wightman Road.

Point 4 on the map: After weaving through the streets of terrace housing, the New River emerges into the north east corner of Finsbury Park:

Where there is a plaque recording the origins and purpose of the river:

The New River stays in just the north east corner of Finsbury Park, before crossing under Green Lanes, and reaching:

Point 5 on the map: where the river runs along a narrow green space between an industrial area to the north, school and housing to the south:

In the height map above, the New River is heading towards the reservoirs and is skirting around some higher land to the south, and this is visible as we walk alongside the river, with a downward slope from right to left requiring the river to be banked on the northern side:

North of the M25, between Cheshunt and Ware, there were a number of points where water was being extracted from boreholes and pumped into the New River. There were no examples of this south of the M25, except for one point along this stretch of the walk where four pipes were pumping water into the river, although it was not clear from where this was being extracted.

There is a brick building visible just to the left of where the water is pouring into the river. This is on Eade Road. It houses infrastructure of some sort, and has a 2003 plaque on the outside, but no indication of its function.

The British Geological Survey borehole map lists a borehole under this building, however it is marked as “Confidential” with no data available.

I assume the water running into the New River is from this borehole, however it is strange as to why the record is confidential.

This section of the walk was incredibly muddy, with some sections rather difficult to pass.

At the end, the path runs up to meet Seven Sisters Road, with an information panel covered in graffiti:

For a short distance, the New River Path has joined with another walking route, the Capital Ring:

And one final loop through housing, with a rather muddy path:

Point 6 on the map: The New River now reaches the reservoirs, with what must have been a gauge house, some means of regulating or measuring the flow of the river, straddling the New River just before the reservoirs:

The New River was truncated at the reservoirs at Stoke Newington in 1946, and now feeds water into the reservoirs, as well as running to their north, through the Woodberry Wetlands, an area surrounding the reservoirs that is now managed as a wildlife haven:

Between the east and the west reservoirs is a building that was once part of the New River infrastructure and has now been refurbished as the Coal House Café. The area outside the café was full of families, so I will not include a photo online, however at the side of the building is a record of the creation of the reservoirs by the New River Company:

Also on the side of the building is a wall tie with the initials of the Metropolitan Water Board, the organisation that took over the running of the New River Company’s assets:

View across the east reservoir:

View across the west reservoir:

And a short walk from the west reservoir, we reach the very end of the remaining route of the New River. The last point in the walk from Ware in Hertfordshire, where the river can be seen above ground. It ends in a rather sad dead end:

Just to the left of the above photo is the wonderful 19th century pumping station built by the New River Company:

The Metropolis Water Act of 1852 required that water companies supplying water to London, filter the water prior to distribution, and that any subsequent reservoirs after filtering be covered. The aim was to improve the quality of water and prevent much of the pollution from an industrial city from entering the water supply.

Prior to the act, the New River Company was supplying water directly from the reservoirs, however the act now required filter beds to be constructed, along with infrastructure such as a pumping station, and the building in the above photo was built between 1852 and 1856 by William Chadwell Mylne, the Surveyor for the New River Company.

The building housed steam engines and boilers until 1936 when these were replaced by diesel engines.

By 1971, the pumping station was rather dated and too small, and the design of the building did not support an upgrade, so the Metropolitan Water Board applied for permission to demolish the building.

There was considerable local support to retain the building as it was such a local landmark, resembling an industrial castle alongside Green Lanes.

This campaign resulted in the building being given a Grade II* listing in 1972, however it would continue to stay empty, and under threat.

The Historic England listing record provides a perfect description of the old pumping station, and why it is known as the Castle (Historic England source here):

“Large building designed to resemble a mediaeval fortress with keep and bailey. 1854-6 by Chadwell Mylne. Stock brick with stone dressings. Battlements and large stepped buttresses all around. The “keep” is of 2 storeys with a tall basement plinth. 6 windows on main south-west front. At north-east and south-west corners round towers with square bartizans the former with a tall conical roof and both having battlements crow-stepped up towards them. Continuous quasi-entablature, with cable moulding, running right around towers. Taller octagonal chimney tower to east. 8 steps (the top one with bootscraper!) to entrance in forebuilding running along north wall and into “bailey” building, which is lower with segmental arcading and 2 slit windows in each bay. Important picturesque landmark.”

The building was empty until 1994 when it was converted into a climbing centre. The large internal spaces perfectly suited for such a use. If you walk past, it is worthwhile having a quick look inside, as the building is still the Castle Climbing Centre.

Leaving the pumping station, we are now following the heritage section of the New River Walk. This section of the route has not seen the New River as a stream of water for many years, as the river was buried in pipes during the 19th century, and since 1946, New River water has ended at the reservoirs.

Point 7 on the map: Here we turn off from Green Lanes and into Clissold Park.

The park retains a couple of stretches of the New River, however these are for decorative purposes only, and start and end within the park.

There is a bridge across one of these decorative runs of the river, which has the arms and motto of the New River Company on the side. “ET PLUI SUPER UNAM CIVITATEM” or “And I caused it to rain upon one city” indicated by the hand reaching down from a cloud, and showering rain drops on the city below.

Part of the decorative New River feature running up to Clissold House:

Leaving Clissold Park, and walking along Stoke Newington Church Street, there is another reminder of the New River with the New River Café on the corner with Clissold Crescent:

Walk a short distance along Clissold Crescent, and there is a reminder of the New River:

The plaque reads “The Park Lane bridge was demolished and the road widened June 1881”.

Park Lane was the original name of Clissold Crescent, and the bridge carried Park Lane over the New River.

A version of the Ordnance Survey map from the 1890s shows the Park Lane bridge and the New River, although by this time, the New River should have been carried underground in pipes, and as the plaque reads, the bridge was demolished in 1881 and the road widened, so I suspect the OS map was not updated at this point (‘Reproduced with the permission of the National Library of Scotland“).

In the above map, the New River heads south between houses, and the route has been preserved and now forms a series of allotments running along the old course of the river:

The path between the allotments ends at Green Lanes (again, almost a constant companion on the southern section of the walk). We cross over Green Lanes to reach;

Point 8 on the map: this is Petherton Road where the New River once ran down the centre of the street, and is now a walkway with trees and grass on either side:

A rather nice ghost sign for Barnes Motors along Petherton Road:

At the end of Petherton Road, the green space gives way to a street which still follows the route of the New River, past Canonbury Station and cross over St Paul’s Road into another section of the New River route that has been transformed into a long green space, with a decorative water feature running the length of the space:

Towards the end of this green space is:

Point 9 on the map: where there is a round brick building alongside the original route of the New River:

The building appears to be a late 18th century watch hut. To protect the New River, the New River Company had a watchman or linesman stationed at points along the route of the river to keep the river clear of debris and also to prevent fishing and swimming in the water, or anything that could pollute the supply.

The brick hut is an example of where such a person would have been stationed to keep watch over the river.

The final stretch of the ornamental water that follows the original route of the New River:

Where the above green space ends, we then walk south along Essex Road, and turn off just before reaching Islington Green, to find Colebrooke Row.

This is another street where the houses were built facing on to the New River, and the space occupied by the river is now a green space running the length of the street.

In the following photo, the houses on the right once looked onto the New River where the grass and trees now run, with the street being on the left:

The white house on the right in the above photo was occupied by the poet and essayist Charles Lamb in the 1820s. The following print shows the house as it was, with the New River running directly in front of the house:

I have written a detailed post about Colebrooke Row and Charles Lambs which can be found here.

Leaving Colebrooke Row, we cross over City Road and Goswell Road, and cut through to St John Street. Then down to Owen’s Row (which is on the alignment of the New River, I wrote about Owen’s Row within this post).

Crossing over St John Street into Rosebery Avenue, and this is the view along the old route of the New River, with Sadlers Wells on the right (a post on Sadlers Wells and the New River is here):

At the end of Sadlers Wells, turn right into Arlington Way, then left into Myddelton Passage, where we come to the official end of the New River Walk, at the viewing platform looking over what was New River Head:

The route is marked on the ground of the viewing platform:

And that completed the New River Walk, over four days / two weekends, from Ware in Hertfordshire to New River Head, Clerkenwell.

It was a fascinating journey, and whilst the route has been straightened at a number of points and does not fully trace the original early 17th century route, it did leave me with considerable admiration for those in the early 17th century who surveyed and built the route, following the contours of the land so it would only fall by roughly 20 feet along the entire route ( 5.5m in total or 5 inches per mile). This enabled the water to flow naturally without the need for any pumping.

You can find my posts covering the first two stages of the walk at the following links:

I have also written about the history of New River Head and London’s Water Industry, which you can find at this link.

In the following panorama from the viewing platform at New River Head, I have labeled some of the key features. On the right are the engine and pump house which will soon become the new Quentin Blake Centre for Illustration, a wonderful new use for these historic buildings.

David Fletcher creates remarkable 3D photogrammetry captures of heritage sites and has one for the historic buildings at New River Head. Hopefully this will work as I have embedded the model in the post (if you do not see this in the e-mail, click here for the post on the website).

You can walk through the site, both inside and out to see this remarkable, historic site in detail:

New River Head by artfletch on Sketchfab

And finally, if you have not had enough about the New River, I purchased the following book, the Mercenary River by Nick Higham a few weeks ago.

It really is a fascinating history of London’s water supply, including, off course, the New River, and is highly recommended.

New River Walk – Cheshunt to Bowes Park

13 Replies

In October of last year, I started the first part of the New River Walk, a walk alongside the 17th century artificial river that was built to bring in supplies of clean water from springs near Ware in Hertfordshire to New River Head in north Clerkenwell.

Some years ago Thames Water signposted a New River Walk that follows the course of the New River as far as is possible, and where it is not possible to walk alongside, the route guides the walker to the next point to access the river.

A couple of weekends ago, on a grey and damp Saturday, we started a second weekend to complete the walk. Starting at October’s finishing point in Cheshunt, and ending at New River Head.

This post covers the New River Walk from Cheshunt to near Bowes Park station, where the river flows into a tunnel heading to Alexandra Palace. A mid-week post will cover the stage of the walk from Alexandra Palace to New River Head.

The route of today’s post can be seen in the following map. Starting at “S”, and with some of the key points covered in the post numbered.

Walking the New River from Cheshunt to Bowes Park

The problem with arranging a weekend in advance is that the weather cannot be guaranteed, and after some sunny weekends, the weekend of the walk turned out grey and damp, with plenty of mud on the path.

The was the scene starting off at Cheshunt:

In the following photo, the large building on the right is the 40 acre site of Newsprinters. As the majority of newspapers no longer run their own print presses, companies such as Newsprinters provide this service to multiple newspapers, so if you read one, it may well have been printed at this site, which is alongside the A10.

A short distance onward, and the results of Storm Eunice were still visible, and would continue to be at a number of points along the New River:

Point 1 on the map: In the following photo the New River opens out into a small lake. The Cheshunt Country Club is behind the trees on the right, and behind the trees directly in front is Theobalds Park:

Theobalds Park is the site of a 16th century palace that was destroyed during the Civil War, and a later stately home which is now a hotel and club.

A London connection with Theobalds Park is that Temple Bar Gate was rebuilt here in 1888 after being demolished from its original location at the point where Fleet Street meets the Strand. The stones of the old gate were purchased by Lady Meux, wife of Sir Henry Bruce Meux (of the Meux’s Brewery Company), who owned the house in Theobalds Park.

The gate was rebuilt in the park, and used as an entertainment venue by Lady Meux.

The gate was relocated to London, with reconstruction and restoration completed in 2004, and the gate can now be seen at the entrance to Paternoster Square, just north of St Paul’s Cathedral.

The gate in Theobalds Park, five years before moving back to London:

(Image credit: Temple Bar, Theobalds Park cc-by-sa/2.0 – © Christine Matthews – geograph.org.uk/p/185643)

Point 2 on the map: Continuing past Theobalds Park, and it was time to cross a major landmark on the route, a landmark that confirmed we were heading towards outer London. This was the crossing of the M25.

The New River flows from source in Ware to the current termination point at the west and east reservoirs by Seven Sisters Road, without any form of pumping. The incredibly slight gradient along the route is just sufficient to ensure a continuous flow of water.

Despite being built in the early 17th century, the New River continues to be a source of water for London, so when the New River meets the M25, the M25 has to give way.

The M25 has to go under the New River, and the river is carried over the motorway within its own dedicated bridge.

This is the point where the river is split into two channels, ready to enter the bridge:

The two channels flow along the bridge, which has a thick concrete slab covering the top:

Looking along the bridge dedicated to carrying the New River over the M25:

Although the bridge carrying the New River over the M25 has a solid concrete surface, this is not a traffic route. There is a track to the Thames Water equipment on either side of the bridge, so the use of a hard surface over the bridge could be to allow Thames Water equipment to move between the two sides of the motorway.

It could also be used to prevent any accidental spillover from the river to the motorway below.

The view looking west from the centre of the bridge:

And the view looking east, at Junction 25 on the M25:

A relatively rural scene at the southern end of the bridge, with a green New River Path signpost showing the way:

The two channels of the New River exit on the south side of the M25:

Colourful graffiti on a rather grey day:

Point 3 on the map: The New River has to cross a number of natural rivers in its route from Ware to New River Head. One of these rivers is the Turkey Brook, which rises just to the east of Potters Bar and heads to join the River Lee Navigation not far from Enfield Lock station.

The Turkey Brook is shown in the following photo, with, in the background the Docwra Viaduct, originally built in 1859, which carries the New River over the Turkey Brook:

Construction of the aqueduct enabled one of the long meanders of the New River to be replaced by a straightened route. The aqueduct was built by Thomas Docwra of Cheshunt, who is presumably the source of the name.

Docwra is an unusual surname, and Thomas Docwra could well be a descendent of another Thomas Docwra who was the Grand Prior of the Order of Knights of the Hospital of Saint John of Jerusalem in England in the early 16th century, and who had their headquarters at Clerkenwell, of which St John’s Gate is a reminder.

According to the Thames Water guide to the walk, somewhere around the Docwra Aqueduct are a number of boreholes which enable the New River to be part of an “Artificial Recharge Scheme”. This is where water is extracted from the New River and pumped into the chalk below ground. When extra water is needed to supply London, it is then pumped back out of this aquifer.

I did not see any evidence of this, but the path diverts slightly around the Docwra Aqueduct, and along the path there were also a number of bland brick buildings with nothing to provide a clue as to their function.

Soon after the Docwra Aqueduct, the evidence of the long straight route of the river enabled by the aqueduct can be seen, along with a number of places where what looked like over sized sandbags lining one side of the river:

Not sure why there would be sandbags, as the New River is not a natural river liable to flood, with water levels in the New River being controlled.

Another casualty from Storm Eunice:

And more evidence of the storm:

Point 4 on the map: The walk has now reached Enfield, and there is very little of the river to see. Originally, there was a loop of the river around Enfield, however in 1900, this loop was bypassed by the construction of three cast iron pipes under the town which carried the river on a more direct route.

This means that the New River Walk now runs through the streets of Enfield, with the green signposts directing the way:

Parts of the original route of the New River around Enfield have been preserved as an ornamental watercourse, and the most attractive part is along the aptly named River View, which starts with the Crown and Horseshoes pub overlooking the old river:

Crown and Horseshoes, River View, Enfield

Looking along River View, with terrace houses lining one side of the footpath, the ornamental remains of the New River on the other side:

The houses on the right in the above photo appear to have their own private bridge over the river to their gardens.

Small park at the end of River View – one of the small bridges over the ornamental New River can be seen on the right:

South of Enfield we pick up the New River again, however it does a number of disappearing acts as it flows through housing estates and other areas where there is no accessible path alongside the river.

Point 5 on the map: This is another point where the New River has to cross a natural stream. It also shows the age of the New River Walk, and that there appears to have been little major maintenance of the walk over the last few years.

Another of the natural streams that the New River had to cross was Salmon’s Brook. This stream has its source in fields north of Hadley Wood station, and eventually flows into the River Lee.

To carry the stream under the New River, a lead lined wooden aqueduct was originally constructed, which was replaced by a brick aqueduct in 1682, which was later largely replaced by a clay embankment and tunnel.

The 1682 arch (known as the Clarendon Arch after the Earl of Clarendon who was the Governor of the New River Company at the time that the arch was constructed) through which the Salmon’s Brook enters the tunnel under the New River was a viewing point when Thames Water originally laid out the New River path, however access to the viewing point has become overgrown and in a bad state of repair and is now closed and fenced off, so it was impossible to get down to the stream and see the arch.

At the top of the viewing point, there is a stone plaque. Very hard to read due to weathering and lack of maintenance, however it dates from 1786 when the New River was raised on a bank of earth over the stream.

The following photo shows the stone plaque and Salmon’s Brook. Originally there was access via steps to the right to see the 1682 arch, which is now a Grade II listed structure.

The arch is the oldest part of the New River to remain, and has an inscription and crest around the entrance to the tunnel:

(Image credit: Clarendon Arch, Bush Hill, London N21 cc-by-sa/2.0 – © John Salmon – geograph.org.uk/p/302364)

Around Winchmore Hill, the New River meanders past larger houses, with gardens backing onto the river:

With New River green signs directing the path along some small diversions:

There are a number of buildings along this stretch of the New River that appear to be pumping stations, however unlike the buildings in the stretch from Ware to Cheshunt, these buildings do not appear to be extracting ground water and pumping into the river.

In the following photo, the building does have what appears to be a concrete channel running to the river, so it may have the capability to pump water from the chalk below, into the river.

Point 6 on the map: At this point, the New River comes up to Green Lanes by the junction with Carpenter Gardens before turning away to head into a housing estate. A couple of stones mark the New River along with a small green space, with the reminder that the New River is “Neither New, Nor a River”:

We can follow the New River for a short distance from the above photo, but it then heads between rows of houses on either side, with the gardens of the houses reaching straight down to the river – so no walking route.

Instead, we walk along the adjacent streets. Here is the aptly named River Avenue, with the New River behind the houses on the left:

I have no idea whether having the New River running at the end of your garden adds to the property price, but it does feature in estate agents descriptions, as there is currently one house for sale in the street that has “fantastic views over the New River and the London skyline • 40ft x 20ft rear garden backing onto the New River”.

Rejoining the New River and more dramatic evidence of Storm Eunice:

The stretch with the marque is along a section of the New River where there is an earth embankment along one side where the river was built along sloping ground and the embankment was needed to ensure the level flow of the river.

At the far end of this stretch, an attempt had been made to close off the access point, presumably due to the marque:

Point 7 on the map: There are two landmarks at point 7. The first is where the New River crosses yet another natural river, this is Pymmes Brook emerging from a tunnel under the adjacent railway line, before it enters another tunnel under the New River:

Pymmes Brook appears to emerge in the golf course, just to the north west of Cockfosters station. As with the other rivers and streams that the New River crosses, Pymmes Brook flows east to where it joins the River Lee.

These streams seem relatively insignificant, however taking a wider view and looking at a topographic map, we can see how they have formed in low ground either side of the higher ground of Cockfosters, and over centuries have probably been responsible for some of the erosion of the lower ground as they drained the area around Hadley Wood.

The second landmark at point 7 is where the New River crosses the A406 – the north circular road seen in the photo below. The bridge carries a railway across the road, the New River is flowing under the road directly in front of where I am standing:

The following photo shows the New River emerging from the tunnel that carries it under the North Circular:

After crossing the North Circular, the New River continues alongside terrace streets. One of the houses backing on to the New River has a faded ghost sign for a Builder and Decorator. An unusual position as the sign was not facing onto any road:

I am approaching the end of the first day of the weekend’s walk, and the New River helpfully provides a natural stopping point.

I have reached Bowes Park (Point E on the map), and here the New River enters a tunnel:

The tunnel was built as one of the 19th century initiatives to straighten out the New River and the tunnel runs from Bowes Park to near Alexandra Palace station, and this straight length of tunnel (built in 1859) reduced the original overall length of the New River by 1.5km.

That was the end of Saturday’s walk. Luckily, public transport serves the New River walk really well. In the upper stretches of the walk, it is close to the line from Liverpool Street up to Ware, and for the walk covered in today’s post, it is close to the line to Moorgate, so from the entrance to the tunnel, it was a short walk up to Bowes Park station.

There are numerous places along the route of the New River which take a name from some aspect of the river. Whether a simple name like River Avenue, or perhaps named after someone associated with the river, and the road that leads from the New River up to Bowes Park station is called Myddleton Road after Sir Hugh Myddleton who was the driving force behind the financing and construction of the New River in the early years of the 17th century.

The name is also displayed on the top of this house in Myddleton Road, that was once the home of Lazaris Family Butchers:

We arrived at Bowes Park station, just as a train was leaving. The next one was cancelled, so the day ended with an hours wait on a windswept platform for a train:

Before I end the post, you may be wondering (or almost certainly not), how the New River is kept relatively clean of floating debris, given the amount of trees that line the side, number of housing estates the river flows through etc.

We did notice that there was more rubbish in the river, the further we headed into London, but we also saw a rather clever cleaning method in use at two locations.

In the following photo, you can see a small cage suspended over the river.

This cage moves along the gantry across the river and is lowered into the river. There is a grating in the river that allows rubbish to collect rather than continue flowing. As the cage is dropped into the river, the lower section opens up as it falls below the surface of the water.

The cage then collects any rubbish collected against the grating, the cage closes, and is raised. It then moves to the right where once over the ground, the cage opens, depositing any collected rubbish on the ground.

The cage is lowered progressively across the river so the whole width is covered.

The whole process appears to be automatic as there was no one visible on the river bank, or building from which to operate the system.

And that is how the New River is automatically cleaned.

Time permitting, the final stage, from Bowes Park to New River Head in north Clerkenwell will be the subject of a mid-week post in the next couple of weeks.

Tunnelling the Baker Street and Waterloo Railway

16 Replies

A couple of week’s ago, I wrote about the construction of the Greenwich foot tunnel, based on a pamphlet published in 1902 by the Institution of Civil Engineers. The pamphlet included details of another recent tunnelling project, constructing the tunnels of the Baker Street and Waterloo Railway (known from the start as the Bakerloo line), under the Thames between Embankment and Waterloo Stations.

Parliamentary Acts of 1893 and 1896 had approved construction of the Baker Street and Waterloo Electric Railway, initially running from Dorset Square near Marylebone Station, to Waterloo Station. Further requests for extensions were approved and by 1904 the line ran from Paddington to Elephant and Castle.

The route of the Baker Street and Waterloo railway ran beneath the Baker Street Station of the Metropolitan District Railway, by Regent’s Park and Crescent Gardens into Portland Place, through Langham Place to Oxford Circus (where the tunnels pass over those of the Central Line with a clearance of only 6 inches at one point), down Regent Street to Piccadilly Circus, along Haymarket and Cockspur Street to Charing Cross, along Northumberland Avenue, then under the Thames to College Street, Vine Street and Waterloo Station.

The majority of the tunnel went through London Clay and was a relatively easy construction project, however there was a challenge where the tunnel went underneath the Thames.

The following diagram from the pamphlet shows the route under the river, from Northumberland Avenue to College Street on the opposite side of the river. The station shown above Hungerford Bridge, labelled Charing Cross Station, is now Embankment Station.

The diagram shows a “River Stage” extending south from Hungerford Bridge. This was a large platform, 50 feet wide and 370 feet long on which were built workshops, stores, steam cranes, boilers and air-compressors, staff buildings along with two shafts down to where the tunnels would be built.

The construction platform and shafts on the Thames were needed due to a strange anomaly found in the bed of the river when test boreholes were made along the route of the tunnels.

In the middle of the river there was a sudden depression in the London Clay through which the rest of the tunnel had been bored. This had filled with gravel, which was porous to water and required a different tunnelling method to the rest of the route, which would use compressed air to help keep out water as the tunnel went through the gravel.

The following diagram shows the route under the Thames of the Baker Street and Waterloo railway, the depression in the London Clay and short distance of gravel through which the tunnel would need to run.

The diagram also shows the shafts sunk down to the level of the tunnels for their construction, along with the temporary work platform created on the river.

College Street on the right is now under the Jubilee Gardens.

Note also in the diagram how the depth of the two tunnels diverge as they route under the Thames, with the “up” line having a rising gradient towards Waterloo (shown as dotted lines) and the “down” tunnel having a descending gradient towards Waterloo.

The ground beneath the streets and buildings of London is generally invisible, but is just as interesting as the surface. I have written about some of the areas where the geology beneath the city has influenced the development of an area, for example, how water shaped north Clerkenwell, Bagnigge Wells, St. Chad’s Place and a Lost Well, and also when oil was found beneath the streets of Willesden.

There are many features below the surface, some as a result of ice and freezing, some as a result of water, for example when the Thames was a much wider river, and the multiple smaller rivers that ran into the Thames, and some the result of human activity.

I wondered whether the feature shown in the 1902 pamphlet was still there. I suspect we look at the Thames at low tide, and assume a uniform bed to the river as it descends from one side of the river, to rise on the opposite side.

The Port of London Authority (PLA) have a complete set of survey and navigation charts on their website, detailing the river from Teddington to Southend. They show a very different view of the Thames, a view that is essential to those on the river. The depth of water, obstructions, navigation lights, moorings etc.

A view where bridges almost disappear, with only the piers supporting the bridge shown on the chart, as these are the key features for those on the river.

The PLA kindly gave permission for me to include an extract from the chart for Lambeth Reach in today’s post, an extract which covers the area where the tunnel for the Baker Street and Waterloo Railway was constructed.

Port of London Authority chart for Lambeth Reach

Hungerford Bridge can be seen in the centre of map, although only shown by black lines, with the piers supporting the bridge as the key feature.

The depth of the water is shown in metres (the depth is the average depth at the lower of each day’s two tides, which should show the minimum depth of water for those travelling along the river). The green areas along each side of the river are where the land is exposed at each low tide, with the height being shown (numbers underlined).

The depth of the Thames is typically between 2 and 3 metres at low tide in the central part of the river, however as can be seen just south of Hungerford Bridge (arrowed) there is a small area where the depth increases to a maximum of 5.4 metres, which is the same area as the depression in the London Clay shown in the 1902 diagram. Today’s Bakerloo line runs a short distance below the deepest area of this depression.

The PLA charts show how the depth of water gradually increases as the Thames heads towards the estuary, which is to be expected. They are some other similar features to the depression by Hungerford Bridge. For example, just off Limehouse Marina, there is a small area where the bed of the river suddenly descends from an average depth of between 6 and 7 metres, down to 11.7 metres, which is quite a depth at low tide.

Returning to the 1902 diagram of the route of the tunnels, it shows the tunnels running under College Street on the south bank of the river. This is one of the many streets that were lost following clearance of the area for the Festival of Britain.

The 1894 Ordnance Survey map shows the location of College Street (underlined in red) in the following extract (‘Reproduced with the permission of the National Library of Scotland“):

Interesting to compare the above map with the PLA chart. In the OS map, the priority is the land, so the river is shown as a blank stretch of water, with no defining features.

The location of College Street today, is under the northern edge of the Jubilee Gardens. The Thames has also been pushed back, with the construction of the embankment and walkway along the river for the Festival of Britain. In the following map, I have marked the location of College Street, pre-1950 edge of the river, where the shafts to the tunnels and the working platform were located, along with the route of the tunnels which today form the Bakerloo line ( © OpenStreetMap contributors).

Looking at the area today, the tunnels of the Bakerloo line, run roughly under the blue van in the photo below. The edge of the grass to the right is the approximate pre-1950 boundary with the Thames.

This view is looking back towards Waterloo Station from the walkway along the south bank, following the route of the Bakerloo line tunnels and College Street:

in the following view, the work platform extended from the first bridge pillars on the opposite side of the river (in front of the white boat) and extended 370 feet to the left. The depression in the London Clay is in the centre of the photo, and the Bakerloo line tunnels are running from the white ship to where I am standing to take the photo.

One of the benefits stated in the 1902 pamphlet of the work platform in the river was that material excavated during the construction of the tunnels could be taken away by barge, saving the transport of large amounts of material through the city’s streets.

The river continues to be used for a similar purpose, with close to the route of the Bakerloo tunnels, a new construction site on the edge of the river for the Thames Tideway Tunnel or the Super Sewer, being dug at a much greater depth to the Bakerloo line tunnels, but with the same need to understand the geology through which the tunnel will be bored beneath London, and to transport materials via the river.

There is a superb aerial view on Google Maps of the above Tideway Tunnel construction site showing the shaft down to the tunnel, which can be found on this link.

The two tunnels of the Bakerloo are each 12 feet in internal diameter, and were located in the gravel bed at a distance of 23 feet apart from the centre of each tunnel. As the tunnels approach the south bank, they move closer and the east bound tunnel will be running vertically over the west tunnel along the old route of College Street. This was done to keep the tunnels within the limits of the street.

Presumably this was done to avoid any damage to the buildings on either side of the street, or to create problems with later construction on the street, where deep cellars may have been built.

To get from College Street to Waterloo underground station, the tunnel crossed Belvedere Road and then routed along Vine Street. This street was also lost during clearance for the Festival of Britain, and in the late 1950s, the Shell Centre complex was built over the site of the street (only the tower block still remains).

I worked in the building during the 1980s, and fortunately working in what would today be called IT (lots of network, radio and telephone cabling), was able to access many of the tunnels built as part of the complex. There were two tunnels between the upstream (with the tower block) and downstream buildings of Shell Centre (on the opposite side of the railway viaduct to Hungerford Bridge). One of these tunnels was for pedestrians, and the other was a service tunnel.

The service tunnel had a raised section which went over the upper tunnel of the Bakerloo line, and it was possible to hear trains rumbling through the tunnels below.

To start construction of the Baker Street and Waterloo railway tunnels, two shafts of cast iron, 16 feet in internal diameter, were sunk from the work platform on the Thames. They reached down 50 feet. I like to assume these cast iron shafts are still below the surface, filled in, as probably too difficult and expensive to remove.

From a chamber at the bottom of the shaft, tunnels were started heading in both directions, with special attention paid to the tunnels under the Thames due to the gravel. The gravel was waterlogged, and at high tide, the combination of river and waterlogged gravel gave a head of 70 feet which created a considerable pressure of water through which the tunnel had to be driven.

A special shield was constructed, weighing 29.5 tons and with an outer steel cylinder of 13 feet in diameter. The shield included 14 hydraulic rams, each 6 inches in diameter, to push the shield forward as the gravel in front of the shield was excavated.

The following diagrams show some of the detail of the shield’s construction, including the hydraulic rams, their controls and the pipes feeding the rams, along with elevations of sections of the shield. Each hydraulic ram could be operated independently

Specially constructed iron rings were designed for the tunnel wall under the river. Each ring was 18 inches wide, and constructed of seven segments. Initially, the joints between the rings were machined to give a smooth fit between rings where bolts were inserted to join the two, however this design was soon revised with rough surfaces on the joints, which were then packed with creosoted pine wood (figures 7 and 9 below).

Gaps were grouted using a specially designed grouting machine (figure 10 above), which applied the grout at pressure, through special grouting holes, to help make the rings water tight.

The first part of the tunnel was through London Clay, however as the tunnel approached the centre of the Thames, it hit the water bearing gravel shown in the diagram earlier in the post. This required a change in tunneling method.

Compressed air was now used to keep the tunnel pressure at a level slightly higher than the pressure of the water through which the tunnel was being bored. This prevented water entering the tunnel, but required adjusted working conditions for the workers, with shifts reducing from 12 to 8 hour shifts.

Air pressure was also adjusted as the tide above rose and fell as the pressure of the column of water above the tunnel through the gravel and the river changed.

As the air pressure in the tunnel was higher than the water column, air would escape from the tunnel, up through the gravel, and could be seen by those on the side of the river as water spouts, with the position of the spouts changing as the tunnel progressed across the river.

The configuration of the shield needed to change as the shield approached and entered the gravel. The following drawings show the shield as it approached and then went through the gravel (called ballast in the diagrams).

Work on the first tunnel commenced on the 19th March 1900. it had taken the previous January and February to construct the shield at the bottom of the shaft. On the 2nd of April, work was stopped to allow the construction of an 8 foot thick bulkhead brick wall in the tunnel. This would form the airlock to the section of the tunnel through the gravel where compressed air would be used.

Tunneling restarted on the 2nd of May and on the 6th of June the shield entered the gravel, and on the 15th July, the tunnel was fully within the gravel.

During the period of tunneling through the gravel, there were a few “blowouts” where water entered the space behind the shield. The design of the shield allowed time for the men working to escape, and provided a means of re-entering sections, and continuing work.

On the 27th September, the tunnel re-entered London Clay, with the last of the gravel seen on the 6th October 1900.

Tests were then carried out by removing the pumped air pressure to check for leaks, repairs carried out and compressed air was ended on the 27th October, with the airlock being demolished in November 1900.

The second tunnel was constructed in 1901, with the majority of the same workers, and using many of the lessons learnt on the first tunnel. This second tunnel was completed separately as the shield from the first tunnel was reused.

There were no deaths during construction, two “illnesses” due to working in compressed air, neither of which appear to have been serious. Workers were provided with hot coffee, clean work clothes, and a place to change before and after work. A doctor was assigned to the project to monitor those working in the part of the tunnels with compressed air.

Figure 11 at the top of the following diagrams highlights the method of tunneling in loose, water-bearing gravel:

The Baker Street and Waterloo Railway commenced services in 1906, from Baker Street to Elephant and Castle. The Middlesex & Surrey Express on March the 9th, 1906 provided a description of the new railway:

“The Bakerloo, London’s new tube railway, running from Baker-street to Kennington-road, will be opened tomorrow. There are intermediate stations at Waterloo, Embankment, Trafalgar-square, Piccadilly Circus, Oxford Circus and Regent’s Park, and a novelty about the new stations is that they are each treated in a separate colour scheme.

A uniform fare of twopence for the whole or any distance is to be charged, and trains will run at frequent intervals from half-past five in the morning until twelve thirty at night. The cars are of the usual type, well lighted, and with good, if not excessive provision made for ‘strap-hangers’ and one can imagine a scramble for straps taking place during the busiest hours. Collisions are rendered practically impossible for a most ingenious system, of automatic signaling has been adopted. Should, however, there be a prolonged breakdown, passengers will be able to leave the trains as a lighted footway has been provided between each stopping place along the whole length of the line.

The booking halls at the various stations are almost palatial in their design, and a feature of the lift accommodation is the use of compressed air in the rapid opening and shutting of the gates. All the wood used in construction has been rendered fire resisting”.

What is not mentioned in any of the news reports covering the opening of the Bakerloo is the tunnel under the river, and the challenges that were overcome in building two rail tunnels through water logged gravel under the Thames.

There was speculation at the time that the depression in the clay was caused by dredging for an earlier tunneling project for the Whitehall and Waterloo Railway.

This was a scheme to build a pneumatic railway in an iron tube under the river, the tube being sunk into the river bed rather than bored. The Railway News on the 20th of May, 1865, provided a description of project;

“THE WHITEHALL AND WATERLOO RAILWAY. Arrangements have now been completed which will admit of the commencement of works of this proposed railway immediately on the necessary Parliamentary powers being obtained. The bill has passed the Commons, it is now unopposed in the Lords and in a few days it may be expected to receive the Royal assent.

The railway is to be worked on the pneumatic principle, and is to be carried under the River Thames from Scotland-yard to the Waterloo Station of the London and South Western. The work must, of course, be finished before the wall of the Thames Embankment on the north side is built up, hence the necessity of pushing forward the preliminary arrangements as quickly as possible.

The railway will be formed by an iron tube, twelve feet in diameter, sunk into the bed of the river and supported in piers – a bridge, in fact, built in, not over the waters. the iron tubes will be made by Messrs. Samuda, and the laying of the tube and the other works will be undertaken by Messrs. Brassey and Co. The principle upon which the line will be worked will be much the same as that adopted on the experimental railway in the grounds of the Crystal Palace. The machinery will be on the Surrey side at the York-road Station.

The whole of the works will be completed in twelve months from the date of commencement. The cost of the undertaking will be about £130,000. The total weight of iron in the tube will be about 5,000 tons, and it will be sunk in four separate sections.”

The project soon ran into financial difficulties, the proposed timescale and costs for the project were hopelessly optimistic. In February 1868, papers were reporting that “The Whitehall and Waterloo Railway is at a complete standstill, and the directors advise the abandonment of the concern, unless, as they say, something turns up between this and the spring. They, of course, hope the South Western will help them in their difficulty, but one would think nothing could be farther from the thoughts of the directors of this company.”

In 1871, the company formed to build the Whitehall and Waterloo Railway was wound up.

The route of this earlier railway did follow much the same route as the later Baker Street and Waterloo Railway, and some parts of the iron tube were found during excavation for the construction of the Shell Centre complex, however I am not sure whether the depression in the London Clay was caused by dredging for this abandoned project.

The shape looks natural, the plan was to dig in the tunnel across the river to bury the iron tube, however the PLA chart shows the change in depth running along the river.

Whether natural or man-made, it was a considerable achievement to bore two tunnels that would become the Bakerloo line, through water bearing gravel, under a considerable head of water, at the start of the 20th century.

If you travel from Embankment Station to Waterloo on the Bakerloo, you will pass through this area of gravel soon after leaving the station.

Walking the New River – Ware to Cheshunt

23 Replies

I have written about New River Head in a previous post, as well as a number of posts about how water has been key in the development of Clerkenwell and parts of Islington.

New River Head was the point where water delivered by the New River was collected and treated, then sent on through an extensive pipe network to London consumers from the east end to Soho and the west end.

The New River was built in the early 17th century, opening in 1613. A very innovative and complex bit of civil engineering for the time as it transported water from springs near Ware in Hertfordshire all the way to New River Head. Helping to transform London’s water supplies, that had depended on water from the Thames along with small local wells and springs, to a constant, high volume supply of clean water.

What is remarkable is that this 400 year old artificial river is still in use, and for the same purpose. Today, the New River provides around 8%, or 220 million litres a day, of London’s water, so if you live in London, there is a good chance that you have drank or showered in water that has reached you via the New River.

The New River no longer runs to New River Head. It terminates at the east and west reservoirs around Woodberry Wetlands, just south of the Seven Sisters Road.

Starting in 1992, Thames Water created a New River Walk that follows the 28 miles from the source to New River Head. 25 miles follow the river from source to the reservoirs, and a further 3 miles makes up a heritage walk that follows the original route of the New River through to New River Head.

I have long wanted to walk the route from the source of the New River, and a few weekends ago, had the opportunity to spend a weekend walking the New River with a small group from Clerkenwell and Islington Guides and the Quentin Blake Centre for Illustration, who will be moving into the historic buildings at New River Head.

My post on New River Head and London’s Water Industry covers the history of the New River, so I will not focus on this aspect in this post, however before starting the walk, a quick look at why a former army officer from Bath, Edmund Colthurst, who had served in Ireland, in 1602 proposed a scheme to bring in water from Hertfordshire springs to a site to the north of the city.

The following map is a heat map (from the excellent topographic-map.com) showing the height of the land around the town of Ware. Blue the lowest, through green, red and to the highest land shown as white:

I have circled the source of the New River. It is here where the New River draws water from the River Lee, and where the Chadwell Springs rise and feed the river. The Chadwell Springs were the original source, with the link to the River Lee added later when more water was required to support London’s growing population.

As can be seen in the map, the source is in a low lying area, there are multiple streams running through the area as well as the River Lee which follows the low lying land to the lower right of the map.

The surrounding land rises, and water collects in the area, providing a significant source for the river.

The Chadwell Spring is the original source of water for the New River. The spring is a large pool of water which is filled with water rising from below ground.

The geology of the area is interesting. Some of the water that rises at the spring comes from the Mimmshall Brook, which, ten miles to the west near Hatfield, drains into a sink hole.

The sink hole forms part of a large underground drainage network called a Karsitic network – an area where the underlying chalk has been dissolved by water forming sink holes and sub-surface drainage networks, which around Hertford and east to the Chadwell Springs covers an area of 32 square kilometers.

The geology of the area means that it was a perfect choice for Edmund Colthurst to propose for the source of the river in 1602.

I refer to the River Lee a number of times in the post. The name can be found with spellings of Lee and Lea. The River Lea is frequently used for the natural river and Lee Navigation for parts of the river where it has been turned into a navigable canal. For simplicity I will use River Lee to refer to any part of the Lee / Lea water system.

Now to start walking the route:

Day 1, Ware to Rye House

The first day’s walk was just under 8 miles in length, which included the walk to get to the source of the New River. The route is well served by the rail network, so starting from Ware station, it was a walk to the source following the dotted red line in the following map (Map © OpenStreetMap contributors):

The blue circle in the above map marks the location of the Chadwell Spring.

The first day’s walk from the source to Rye House is shown by the red dotted line n the following map:

After walking from Ware station, along the River Lee, the first sign of the New River comes with New Gauge House on the banks of the River Lee:

At the side of New Gauge House are two signs, the one on the left is part of the original signage covering the path alongside the river, the sign on the right shows that this is still a working bit of water supply infrastructure, with appropriate safety precautions.

Looking west along the River Lee, with New Gauge House on the left, and on the right in the river is the infrastructure that allows water to be drawn off from the Lee into the New River.

The following view shows New Gauge House, with the start of the New River coming from the arch below, where water from the River Lee starts its journey south to provide water for the population of London.

New Gauge House was built in 1856. The equipment that controls the flow from the Lee is in the ground floor of the building, and accommodation for a Gauge Keeper was in the floor above.

According to the Historic England listing, 22.5 million gallons is taken each day from the Lee into the New River.

Looking south along the start of the walk:

Looking back along the New River to New Gauge House, slightly hidden by trees, with the higher ground, part of the higher ground that surrounds the area, seen in the background.

As shown in the heat map at the start of the post, this is a low lying area, with large amounts of water lying across the surface of the land:

Signposting from the creation of the New River Path:

A straight stretch of the New River with the A10 road crossing:

Underneath the A10:

It is theoretically possible to get to the Chadwell Spring, however the area around the spring is very overgrown and wet, and required a detour from the main path. The Chadwell Spring rises into a circular pool.

This is the view looking in the direction of Chadwell Spring from the walk alongside the New River:

This is the White House Sluice. The building originally contained the equipment to control water levels on the river:

The most historic building here though is the Marble Gauge photographed below:

The Marble Gauge was built in 1770 to control the water taken from a former inlet to the River Lee. Today, the Marble Gauge does not have any function, and water flows through a couple of iron pipes to bypass the structure.

The Marble Gauge was designed by Robert Mylne, the architect and engineer to the New River Company. The structure, along with the railings shown to the left of the above photo are both Grade II listed.

“This Belongs To New River Company” – stone in the undergrowth to the side of the river:

When completed in 1613, the Chadwell Spring was the furthest north of the sources feeding the New River. The connection to the River Lee would not come until Parliament approved a 1738 Statute that allowed the company to take up to 102 megalitres a day from the River Lee (a significant additional source compared to the original 10 megalitres a day from the Chadwell and Amwell Springs).

Whilst the River Lee provided a considerable additional supply of water for London, it did not please barge and mill owners who were concerned about the impact that such a loss of water would have on their use of the Lee.

The photo below shows the channel from the Chadwell Spring where it joins the New River:

A significant additional source of water was added to the New River during each of the river’s first three centuries.

During the 17th century, the springs at Chadwell and Amwell provided the water. In the 18th century, water from the River Lee was added, and in the 19th century a number of pumping stations were built along the northernmost stretch of the New River. These pumping stations extracted water from bore holes to add to the river.

The first of these is the Broadmead Pumping Station, built in 1881:

Whilst many of the pumping stations are still in use, Broadmead seems to have been converted to offices, and is currently the offices of a car hire company. The building and adjacent chimney are Grade II listed.

The New River then passes through Ware, just to the south of the station, and continues on parallel to the A1170 London Road:

In the above photo, there is a concrete wall projecting out into the centre of the river. A small figure can be seen at the end of the wall:

The figure is part of the Chadwell Way Sculpture Trail, which consists of 31 small bronze sculptures made by a class of 7 and 8 year old children from St John the Baptist Primary School in Great Amwell.

The above sculpture is called “Murphy and his Dog”, by James. The leaflet detailing the trail can be found here.

The river soon moves away from the London Road, and we reach the village of Amwell, where the Amwell Spring adds water to the river. To mark the location, there is a small island in the river:

The monument in the above view has the following inscription:

An appropriate inscription to think about whenever we turn on the tap.

Walking past the island, and at the opposite end is another monument, with a Latin inscription facing the path:

And the following inscription on the other side of the monument:

A short distance along the New River is Amwell Marsh Pumping Station, a Grade II listed building, completed in 1883:

The British Geological Survey have the bore hole record for the boreholes under the pumping station. The record dates from 1899 and details two boreholes 5.25 feet diameter at the top, reducing to 4 feet diameter at the bottom of the boreholes, which are 109 feet deep.

The combined boreholes had a total pumping capacity of just over 7 million gallons in 24 hours, and that when pumping stopped, water rises quickly within the boreholes.

A note in the record shows that the water pumped from below ground is part of a much larger underground water system as the record states “Pumping here affects Amwell springs, Amwell Hill Well and Chadwell spring”, so whilst water can be pumped from the boreholes, the total impact on the water system needs to be considered.

Amwell Marsh pumping station is still extracting water. The steam pumping engine has been replaced with electric, and looking into the New River we can see the turbulence created by water being pumped into the river:

A Metropolitan Water Board sign warning that fishing is strictly prohibited, trespassers and persons throwing stones will be prosecuted, and that any person bathing, washing an animal, or otherwise fouling the water is liable to a penalty of five pounds:

Not sure of the age of the sign. The Metropolitan Water Board was formed in 1903 when it took over the New River Company. The notice is signed by A.B. Pilling, Clerk of the Board. Pilling was authoring books about the new Chingford reservoir in 1913, so the sign must date from the early decades of the 20th century.

A quiet stretch of the New River:

Rye Common Pumping Station, another Grade II listed building, constructed in 1882.

As with the other 19th century pumping station on the route, it was originally steam powered, but was converted to electricity in 1935. As can be seen from the water gushing from the pipe into the river, Rye Common is still contributing to the New River and London’s water supplies.

The New River, running alongside a housing estate:

The New River is now approaching Rye House, with the three chimneys of Rye House Power Station in the distance.

And at Rye House, the first day of walking the New River ended, with the conveniently located Rye House station a very short walk from the river.

Day 2, Rye House to Cheshunt

Day 2 of walking the New River, a stretch that will take us from where we finished yesterday at Rye House, along the route of the New River to Cheshunt – the route highlighted by red dashes in the following map (Map © OpenStreetMap contributors):

An overcast and grey Saturday was followed by a sunny Sunday. Not long after leaving Rye House, the route reached Essex Road Pumping Station (difficult to photograph, just a very small part of the brick wall is on the right of the following photo), with new building on an old industrial site in the background.

Two large pipes from Essex Road Pumping Station discharging water into the New River:

Essex Road Pumping Station draws water from a borehole beneath the building. The borehole consists of an upper shaft of depth 54 feet and average diameter of 7 feet, followed by a bore hole which extends to a depth of 403 feet below the surface.

The bore hole record demonstrates that there is a considerable volume of water not that far below ground. In 1920, water would rise to a level 2 feet below the surface, and without pumping, this standing water level does not vary.

The record stated that the bore hole would yield 2,160,000 gallons of water a day.

A short distance after Essex Road Pumping Station is a new road bridge that carries Essex Road over the New River:

The walkway alongside the New River carries on under the bridge, with some appropriate artwork lining the under side of the bridge:

After passing through some housing and industry around Rye House, the New River regains its rural setting, with views helped by the sunny weather after the previous day’s rather grey walk:

It is rather hypnotic watching the flow of the water in the river. Leafs and twigs are carried along at the equivalent of a fast walk. The only turbulence at the occasional sluice and where pumping stations add water to the flow.

To the west of this stretch of the New River are some rather nice houses that make the most of having the New River passing the end of their gardens:

Before returning to a tree lined river:

We then come to the 1887, Grade II listed, Broxbourne Pumping Station:

This is a pumping station that is still in use, extracting water from deep below the surface and adding to the New River. Some turbulance can be seen at the right edge of the photo where water is pouring into the river. There are two other pipes pointing onto the river which must have been used in the past, as this was a pumping station that produced a considerable quantity of water.

The bore hole records for the Broxbourne Pumping Station state that there is a shaft below the building to a depth of 197 feet. It is a large shaft of 14 feet diameter at the top down to 10 feet diamter at the bottom. The bore hole record implies that there are additional bores heading out from the shaft.

The 1909 record states that the standing level of water is only 8 feet below the surface, again indicating how high the water table is along the route of the New River. The 1909 record stated: “Great quantity of water, the temporary pumps being drowned in sinking when 2 to 3 million gallons a day were got out. The yield has been returned as 4,500,000 gallons a day”.

There was a chimney at the pumping station which has been demolished, as along with the other pumping stations along the New River, it was converted from steam to electric. There is though a considerable amount of infrastructure to the side of the building. No idea whether this is still in use, however (if you like that sort of thing, which I do), there are some wonderful green painted tanks to the side. The Historic England listing makes no mention of these, only referring to the building.

It is not just the pumping stations that are listed along the route of the New River, also one of the train stations. This is the rather wonderful Grade II listed Broxbourne Station, built between 1959 and 1961 by the British Railways Eastern Region Architect’s Department:

Broxbourne Station is next to the New River. In the above photo, the New River embankment is the grass seen at the lower left corner.

Whilst this is the closest station to the New River, stations are not that far away for the majority of the walk, and the rail line is here for the same reason as the New River.

The New River needed to follow a route that was almost flat, with a very shallow drop in height from the springs to New River Head. This would ensure a smooth flow of water without any need for pumps.

The valley created by the River Lee and associated water systems had created a relatively low and flat wide channel of land between higher ground on either side.

This enabled the New River to follow the 100 foot contour (height above sea level) almost from source to destination, and the height of the river dropped by only around 20 feet along the entire route. Given the surveying methods and equipment of the early 17th century, it was a remarkable achievement.

This relatively flat land was also ideal for the rail network, which avoided the need to construct tunnels or large embanked routes for the railway, so the New River and railway ended almost parallel to each other.

The following map from topographic-map.com shows the lower land as the blue in the centre, with Walthamstow towards the bottom of the map and Ware at the top. The New River follows the light blue along the left of the blue of the Lee Valley.

Continuing along the New River into Broxbourne, and the river runs around the church of St Augustine’s.

As the New River Path gets into more built up areas, there are now sections where it is not possible to walk alongside the river. Fortunately these are for short lengths, and a quick diversion is needed to get back to the river.

The following photo shows one such section where the river runs through private gardens, A 1926 road bridge crosses the river.

In the following photo, the Mylne Viaduct (part of which is the low wall to the left) carries the New River over the Turnford Brook which runs below the New River, left to right.

The New River has been straightened in places from the original early 17th century route. I have not yet had the time to compare the route today with the original, however I suspect the view in the above photo is of one of the later, straightened sections.

The river is carried on a high earth embankment, which may have been too difficult for the original entirely manual construction method, but easier with later mechanical earth moving.

The New River then passes under the A10. The walkway has a slight diversion through a pedestrian tunnel under the road.

The New River then returns to a rather rural environment, with a large bush growing over half the river. Not sure how much maintenance of the New River is needed today, or is carried out by Thames Water to keep the course of the river open.

Although the New River passes through a number of built areas on the way to Cheshunt, it continues with a rather rural appearance with trees lining the banks. Small foot bridges ensure crossing points as the river winds through communities.

Sluice to manage water levels on the outskirts of Cheshunt:

Passing alongside a new housing estate:

The creation of the New River Path dates back to the early 1990s, and the path continues to be well sign posted with only a few places where some careful reference to the map is needed. This may well change as we get into the built areas of north London.

At the end of Day 2 – an autumn scene in Cheshunt:

From here it was a walk into Cheshunt to return home. The end of a brilliant weekend walking the New River.

Each day was just under 8 miles (which included getting to and from each day’s starting and end point). The early stages of the walk around Ware were wet and muddy in places, after Ware the path was mainly dry and easy to walk.

My thanks to those also on the walk for making it such an enjoyable weekend. We have a second weekend booked in a few weeks time, with an aim of walking from Cheshunt to where the New River currently terminates at the East and West Reservoirs, just south of the Seven Sisters Road.

The next stage will include the symbolic crossing of the M25, where rather surprisingly the New River crosses over, rather than under the M25.

Swanscombe Peninsula and the London Resort – Part 2

11 Replies

This post continues my walk exploring the Swanscombe Peninsula. The previous post covered the section marked in red in the following map, and this post covers the route in blue, alongside Botany Marsh.

The eastern and southern sides of the Swanscombe Peninsula are more industrialised than the western side, and the noise from these sites is starting to be heard above the breeze blowing through the thick fields of grasses and reeds.

The footpath follows the eastern edge of an area known as Botany Marsh, and the wet nature of the land is very obvious, despite September having slightly less rainfall than the average for the month.

Electricity pole in the marsh:

In the following photo we can see all the infrastructure needed to carry high voltage electricity across the River Thames. On the left is the pylon on the north bank of the Thames in Thurrock, with slightly to the right, the pylon on the peninsula. These two pylons carry the cables across the Thames. In the middle is the tower catching the descending cables and from this tower cables run off across north Kent.

View to the south west across Botany Marsh. More water and the chalk cliffs which are the boundary to the south western edge of the peninsula.

The Swanscombe Peninsula has long been the site for large industrial companies that needed access to the river for transport of raw materials, and space for large processing plants. One of these companies in operation today is the Cemex Northfleet Wharf and Concrete Plant:

The concrete plant has a wharf on the eastern edge of the peninsula where the raw materials for the manufacturer of concrete, aggregates, asphalt and mortar are landed.

Looking in the opposite direction and the peninsula is still wild and wet. Fortunately I did not need to take this footpath.

The western side of the peninsula is more open, however walking along the eastern edge of Botany Marsh, and there are some lovely stretches of footpath, with banks and tall bushes on either side. It feels like walking in the depths of the countryside rather than a site with industry, a Greenhithe housing estate and the Thames all a short distance away.

However evidence of industry along the edge is not far away, and the noise of lorries running to and from the plant now compete with the breeze through the grasses.

This adds to the wonderful contradictions of the peninsula. look one way to see industry, look the other to see the most wonderful landscapes, with Botany Marsh really living up to its name:

The road that provides access to the industrial areas also provides access to the peninsula, with some limited parking for cars. At one of these entrances is an information panel which tells how the peninsula is managed, and the wildlife that can be seen on Botany Marsh:

Botany Marsh is subject to land management to maintain the biodiversity of the place. Without management, the land would revert to scrub and woodland. Ditches were cleared and the footpath I have been walking along during this part of the walk was created.

The information panel also explains where much of the water comes from. A system to collect water from 20,000 square metres was installed which increased the water flow into the marshes by up to 10,000 cubic metres a year. The water is run through an oil interceptor to ensure the marsh is not polluted

The rear of the panel provides information on the species of animals that can be found across the marsh, many of which have seen a severe decline in numbers over the last couple of decades. Three of the six reptiles native to Britain are found on Botany Marsh (grass snake, slow worm and vivaparous lizard).

Campaigning to save the peninsula from development has included the need to designate the area as a Site of Special Scientific Interest. The uniqueness of the place, diversity of animal species, the rarity of such a variety of habitats all support an SSSI designation.

In March 2021, an existing SSSI to the south (Bakers Hole – a back filled quarry that was the site of many finds of Stone Age occupation), was extended to include most of the Swanscombe Peninsula.

Consultation on the recommendation to extend the SSSI took place between March and July and a recommendation to the Board of Natural England will be made based on the results. The Board then have until the 10th of December 2021 to either confirm or withdraw the recommendation.

The London Resort are looking at ways that this recommendation can be withdrawn or accommodated within their plans, so the outcome for both the London Resort and the Swanscombe Peninsula is not yet clear.

Map and details of the proposed SSSI are on display at all the main entrances to the peninsula:

As well as the Cemex site, another industrial company on the eastern side of the peninsula is Britannia Refined Metals, a company owned by the multinational Glencore. The company specialises in lead, zinc and tin production.

Given the current shortage of HGV drivers, and the poor facilities provided for them, the above photo provides an example. To the right of the photo was a long layby off the road for lorry parking. The blue box behind the site safety sign appeared to be their only toilet facilities.

Britannia Refined Metals was originally formed around 1930 as the Britannia Lead Co. Ltd, and their original brick building is still onsite with the name above what was probably the original main entrance to the site.

After having a looking at the industrial side of the peninsula, I walked back to Botany Marsh to continue south along the footpath.

Old building on the northern edge of the southern industrial area gradually being overgrown:

Although there are some large industrial sites along the eastern side of the peninsula, they are not that visible, apart from the very tall chimney of the Cemex works. More reeds, grasses and water of Botany Marsh.

The path I was following south, then turned towards the west, to loop back inland. I suspect it ended up at the flooded footpath shown earlier in the post, so after a lengthy detour, I turned back to access the road at the site of the Britannia factory.

Following this road south took me through an industrial estate, very similar to those that have traditionally lined the River Thames, but I did not expect to find a number of London buses:

This is the site of London Bus and Truck Ltd – “For All Your Bus, Coach & Commercial Vehicle Requirements” and specialists in Routemaster buses which explains the small fleet of buses in their parking area:

A bit of protection for pedestrians from the many HGV’s passing along the road:

At the end of the road running through the industrial estate, it meets the A226, or Galley Hill Road, and I followed this busy road to head for Swanscombe station. The road runs across the bridge seen in the distance in some of the photos in today’s posts. The height of the road provides a good view across the Swanscombe Peninsula, and also shows where HS1 enters the tunnel under the peninsula to cross underneath the River Thames:

HS1 is the high speed railway running for 108km between Paris and St Pancras Station. Regular services started on the route on the 14th November 2007. The entrance on the Swanscombe Peninsula is the start of a one and a half mile tunnel under the Thames.

There are industrial sites lining the southern end of the peninsula, on either side of HS1. These industrial sites are also included in the land required by the London Resort. As development has extended east along the Thames from central London, many of these industrial estates have been closed and built over with housing. They are though a much needed part of economic infrastructure.

The view from the bridge shows what appears to be grass and bushes over the northern part of the peninsula. It is not really possible to appreciate the natural diversity of the place from this viewpoint and a walk through the site is needed.

The London Resort describe one of the benefits of their proposals as the regeneration of what is largely a brownfield site. This is true, the peninsula has been the location of both industry, the infrastructure needed to support these industries and connect them to the river, along with the dumping of waste from these industries. However just describing Swanscombe Peninsula as a brownfield site does not fully appreciate the site today. A site which has been considerably reclaimed by nature, is home to many endangered species and also retains that sense of isolation that was so prevalent across much of the land along the river to the east of London.

I also like the industrial sites that are found on the east side of the peninsula. They are there because of the river, the river that has transported so many raw materials and finished products across the centuries.

The road bridge taking Galley Hill Road over HS1. This was the exception when there was no traffic. During my walk along the road there was an almost continuous line of cars and lorries.

The River Thames is always in the background around the peninsula, with shipping moored at, and travelling past Tilbury visible:

From the bridge we can view the chalk cliffs that line part of the south western edge of the peninsula:

There are a number of chalk pits on the peninsula, and the wider Swanscombe area is one of Europe’s most important Paleolithic sites (500,000 BC to 125,000 BC). Finds in the area include hand axes, and what became known as the Swanscombe Skull, which was excavated in Barnfield Pit, a short distance south of the peninsula (part of the extended SSSI). The area also includes evidence from some of the temperate periods between periods of glaciation, or ice ages.

The skull was discovered in 1935 by Alvan T. Marston, one of the many archaeologists who had been working in Swanscombe. He described the discovery as follows:

“For nearly half a century, archaeologists have known the high terrace gravels at Swanscombe, Kent, and in that time have found hundreds of thousands of the early Stone Age hand axes belonging to the Chelles-Acheulean stage, but the constant hope that skeletal remains of the makers of those implements might be found did not become fact until June 1935, when I discovered a human occipital bone 24ft below the surface in the middle gravels of the Barnfield Pit. Nine months later a second bone of the same skull was found, the left parietal, in the same seam of gravel and at the same depth below the surface. The two bones were 8 yards apart, many tons of sand and gravel having to be excavated and examined to bring the second bone to light, and this work is still going on.

Swanscombe is not homo sapiens. It is, as its geological horizon shows, a pre-Neanderthal hominid.”

And with that diversion, I reached Swanscombe station, ready for the train back to Waterloo East:

This is the first time I have been to Swanscombe Peninsula. No doubt the weather helped with first impressions, however it was a fascinating walk through such an interesting area.

This is a place that is incredibly unique. Fresh water marsh to the south and salt water marsh to the north has created different environments, with a wide variety of animal species populating the peninsula.

The peninsula is also very quite, I walked through on a Friday, so it is possibly busier at the weekend, however I saw five people at most, only one close up – a jogger on the eastern side of the peninsula.

Jobs are really important and are needed in north Kent, and it is always a difficult argument, however the planned resort / theme park does seem to be in the wrong place.

It does not occupy the whole of the peninsula, however it would have a dramatic impact on the remaining land. Construction work, drainage, impact on the water table, noise and light would all have an impact on the surrounding environment and animals. Many of these animals are threatened, with, for example, Swanscombe Peninsula being one of only two known places where the jumping spider Attulus distinguendus can be found.

The development would also disrupt the movement of animals between the peninsula and the wider environment.

The board of Natural England have until the 10th of December 2021 to make a decision on the SSSI extension to the peninsula. It will be interesting to see their decision and the impact this may have on plans for the London Resort and the future of Swanscombe Peninsula.

If you get a chance to visit, a walk through Swanscombe Peninsula is a really good day out.
