Would It Be Possible For The Bakerloo And Watford DC Lines To Use The Same Trains? – 6th March 2023 Update
These two lines are very different.
- The Bakerloo Line is a classic London Underground Line with 25 stations and services run by 1972 Stock trains.
- The Watford DC Line is part of the London Overground with 19 stations and services run by Class 710 trains.
Ten stations are shared between the lines, of which only one; Queen’s Park offers level boarding.
The Shared Stations
The nine shared stations often have considerable steps up and down, as at Willesden Junction station, which is shown in Train-Platform Interface On Platform 1 At Willesden Junction.
I am rather pleased and pleasantly surprised, that there are not more accidents at the shared stations, but using the line must be a nightmare for wheelchair users, buggy pushes and large case draggers.
If Transport for London proposed building a line like this, they would have to launch it at the Hammersmith Apollo, where comedians perform.
The One Train Type Solution
To my mind, there is only one solution. The two services must use the same type of trains.
These are a few thoughts on the trains.
Trains Would Be Underground-Sized
As the trains will have to work through the existing tunnels to Elephant & Castle station, the trains would have to be compatible with the tunnels and therefore sized for the Underground.
I suspect they would be a version of the New Tube for London, that are currently being built by Siemens for the Piccadilly Line.
New Tube For London And Class 710 Train Compared
This Siemens infographic summarises the New Tube For London.
These figures are from Wikipedia.
- Cars – NTFL – 9 – 710 – 4
- Car Length – NTFL – 12.6 metres – 710 – 20 metres
- Train Length – NTFL – 113.4 metres – 710 – 80 metres
- Seated Passengers – NTFL – 268 – 710 – 189
- Total Passengers – NTFL – 1076 – 710 – 678
- Passenger Density – NTFL – 9.5 per metre – 710 – 8.2 per metre
- Speed – NTFL – 62 mph – 710 – 75 mph
Note.
- The figures for the Class 710 train are for a four-car train.
- The passenger density and speed are closer than I thought they’d be.
- I’m sure Siemens can design a longer and/or faster train if required for the Euston service.
I feel that the New Tube for London design could be adjusted , so that it could work the Watford DC service.
Platform Modifications
I suspect that the New Tube for London will be lower than the Class 710 train and all platforms would need to be lowered to fit the new trains.
I would also suspect that it would be easier to lower platforms, than modify them, so that they had dual-height sections to satisfy two classes of train.
It should be noted that the New Tube for London has shorter cars than the sixteen metre 1972 Stock trains currently used on the line, so there will be smaller gaps at stations with curved platforms like Waterloo.
I believe that with one class of train, all of the stations on the Bakerloo and Watford DC Lines could be made step-free between train and platform.
Platform Height On Platform 9 At Euston
I took these pictures on Platform 9 at Euston station.
Note that it is rather a high step into the train and there is a large gap.
But if say, a modern London Underground train from say the Victoria Line pulled into the platform would it be a better fit?
Platform Height At Kilburn High Road Station
These pictures show Kilburn High Road station.
I should have taken more pictures, but the step between the platform and train is similar to Platform 9 at Euston.
Platform Height At South Hampstead Station
These pictures show South Hampstead station.
I should have taken more pictures, but again the step between the platform and train is similar to Platform 9 at Euston.
Were The Platforms At Euston, South Hampstead And Kilburn High Road Built For Another Class Of Train?
This Wikipedia entry is for the London Underground Watford Joint Stock train, where this is said.
The Watford Joint Tube Stock was built for the service to Watford along both the Bakerloo tube and the London North Western Railway. As a result, the cars were owned by both the Underground and the London North Western Railway. To be able to operate on both lines, the car floors were 4+1⁄2 inches (110 mm) higher than other tube cars. This was a compromise height between the platform heights on the two lines.
The cars were ordered in 1914, but construction was delayed by The First World War. As a result, the first cars were not delivered until early 1920.
Note.
- The Wikipedia entry has links to some images of which this is one.
- They must have been rather cramped trains if they were built for deep tunnels and had a floor that was 110 mm higher, than other tube trains.
It certainly appears to be possible to design a train, that would fit both lines.
But would it fit modern regulations and give full step-free access?
Queen’s Park And Euston
This map from cartometro.com, shows the route between Queen’s Park and Euston stations.
Note.
- The Watford DC Line is shown in orange.
- Queen’s Park station is to the West of Kilburn High Road station.
- It appears that Watford DC Line trains always use Platform 9 at Euston station.
The route seems to be a self-contained third-rail electrified line into Euston station.
On the subject of electrification between Queen’s Park and Euston stations, there would appear to be a choice between the third-rail system and London Underground’s four-rail system.
But it is rumoured that the New Tube for London will have a battery capability.
As Euston and Queen’s Park stations are only 3.7 miles apart, perhaps the choice would be to use battery power into Euston station, which would remove electrified rails from Euston?
How Many Trains Could Run Into Euston?
Currently, four trains per hour (tph) run into Euston.
It is generally accepted that six tph can use a single platform. But would this be enough?
I suppose there is the possibility of tunnelling under Euston station to a pair of terminal platforms.
In that case the current platform could be used by other services.
Southern’s Milton Keynes And Clapham Junction Service
This service wouldn’t be affected as it uses the fast lines between Willesden and Watford Junction.
Advantages Of One Train Type On The Bakerloo And Watford DC Lines
I can think of these advantages.
- Step-free access between train and platform, should be achieved.
- A unified fleet.
- A higher frequency between Euston and Willesden Junction stations.
- Higher frequency where needed.
- If trains had a battery capability, Euston could be free of third-rail electrification.
As only one type of train will be using the Watford DC line between Euston and Watford Junction, this could result in operational efficiencies.
Linking Of The Bakerloo And Abbey Lines
This could be the biggest advantage of all.
This map from cartometro shows the lines at Watford Junction station.
Note.
- The orange lines are the current Watford DC Line services of the London Overground, terminating in platforms 1 to 4 of Watford Junction station.
- These lines would be taken over by the unified Bakerloo/Watford DC Line services, running nine-car New Tubes For London.
- The next station to the South is Watford High Street.
- The West Coast Main Line goes through the station and uses platforms 5 to 10.
- At the North of the station is Platform 11 on the Abbey Line which leads roughly North East to St. Albans.
Look at how the Abbey Line is more or less in line with the twin-tracks of the Watford DC Line.
Recently, during the Bank Station Upgrade, a 488 metre long single track tunnel was built to divert the Southbound Northern Line.
This tunnel was not dug with a tunnel boring machine, but traditionally by hand, using men, picks, shovels and I suspect a few small machines.
I believe, that a similar technique could be used to dig a tunnel, to connect the Abbey Line and the Watford DC Line.
- It would only be single-track
- It would probably be less than 500 metres long.
- It would connect to the Abbey Line to the South of Platform 11.
- It would be deep-level tube-sized.
- It might be dug by hyperTunnel.
- Geography wouldn’t allow the tunnel to terminate in the Watford DC Line platforms at Watford Junction station.
But where would the terminal be on the Southern side of the West Coast Main Line?
This map from OpenRailwayMap, shows the two routes between Watford Junction and Bushey stations.
Note.
- Watford Junction station is at the top of the map.
- The orange line is the West Coast Main Line.
- The yellow line looping to the West of the West Coast Main Line is the double-track Watford DC Line.
- Bushey station is at the bottom of the map, where the two rail lines meet.
- Watford High Street station is in the middle of the map on the Watford DC Line.
The new service could certainly take the Watford DC Line as far as Watford High Street station.
- The station is close to the centre of Watford, the hospital and Vicarage Road stadium.
- But there is no space for a terminal platform.
This second OpenRailwayMap shows the disused railways to the West of Watford High Street station.
Note.
- The yellow loop at the East of the map is the Watford DC Line.
- Watford High Street station is on this loop.
- There is a triangular junction, that connects the former Croxley Green branch to the Watford DC Line.
- The terminus at Croxley Green station is marked by a blue arrow.
- There used to be intermediate stations at Cassiobridge, Watford West and Watford Stadium.
- This route was used for the failed attempt to build the Croxley Rail Link.
But could a Western extension of the Abbey Line be built?
- It would terminate at either Croxley Green or Cassiobridge.
- There would be intermediate stations at Watford West, Watford Stadium and Watford High Street.
- There would be two tph.
- Trains would be nine-car New Tubes For London.
- The current Abbey Line is 6.4 miles and would be run using battery power, with possible charging at St. Albans Abbey station.
- The tunnel under the West Coast Main Line would be run on battery power.
- The Western extension from Watford High Street station would be run using battery power, with possible charging at the Western end.
I believe, an extended Abbey Line could be a viable alternative to the ill-fated Croxley Rail Link.
- I have used battery power, as I doubt Health and Safety would allow any new third-rail electrification.
- I have used nine-car New Tubes For London for the extended Abbey Line, as their small cross-section would allow a smaller tunnel and they would be certified for running in tunnels.
- Some platforms on the Abbey Line would need to be lengthened, but these would be the only modifications, other than the possible installation of the charging system.
- The extended Abbey Line would serve Watford Hospital and Vicarage Road.
The capacity of the extended Abbey Line would be substantially more than the current line.
Conclusion
A common fleet used by the Bakerloo and Watford DC Line would appear to give advantages and it has been done successfully before.
But what the Bakerloo Line, the Watford DC Line, the Abbey Line and the Bakerloo Line Extension need is a good dose of holistic design.
Thoughts On Watford DC Line Electrification At Euston Station
I was in Euston station this morning and took these pictures of the electrification on Platform 9.
Note.
- Watford DC Line trains usually use Platform 9.
- The first two pictures show the 750 DC third rail electrification.
- The last three pictures show the 25 KVAC overhead electrification.
- The train is a five-car Class 710/3 train, which is a dual-voltage train.
The train’s pantograph was in the down position, as far as I could see.
This Google Map shows the ends of Platforms 6 to 11 at the station.
Note.
- The platforms have their numbers painted on the end.
- The train in the top-left corner of the image is in Platform 5.
- Platforms 9 and 10 appear to be fitted with 750 VDC third-rail electrification.
- All Platforms also seem to have 25KVAC overhead electrification.
So platforms 9 and 10 appear to be able to handle trains which need either form of electrification. When I took the first set of pictures, there was a Class 350 train in Platform 10.
These dual voltage platforms 9 and 10, may help with the operation of the station.
I have some questions.
Do TfL Intend To Increase Watford DC Line Services?
Currently, the services on the Watford DC Line are as follows.
- Four trains per hour (tph) between Euston and Watford Junction stations.
- In the last few weeks, I’ve seen both four-car Class 378 and five-car Class 701 trains on the route.
- All trains that work the route appear to be dual voltage.
This TfL infographic illustrates their plans.
It says Watford and Euston would be run by five-car trains at a frequency of four tph.
TfL have ordered six five-car Class 701/3 trains for the Watford DC service.
Will The Watford DC Platforms Be Moved In The Euston High Speed Two Rebuild?
The operation of the Watford DC Line works well at present, but as Euston station is going through a major rebuild for High Speed Two, the platforms could be moved or rebuilt.
Would Health and Safety object to laying third-rail electrification and insist that Watford DC services used 25 KVAC to access Euston?
They could do this, as all trains running on the Watford DC Line are dual-voltage trains.
Would Removing Third-Rail Electrification From Euston Station Improve Safety?
Health and Safety would say it did and as the trains are dual-voltage, they could transition at Queen’s Park or South Hampstead stations.
An Alternative To Changing The Electrification
The distance between Euston and Queen’s Park stations is just under four miles.
In Will London Overground Fit On-board Energy Storage To Class 378 Trains?, I asked whether it would be worthwhile.
I finished with these two sentences.
I have no idea how much electricity would be saved by regenerative braking on the London Overground, but various applications of regenerative braking technology talk of electricity savings of between ten and twenty percent.
I think it is only a matter of time before the technology is proven to be sufficiently reliable and the numbers add up correctly for the Class 378 trains to be fitted with on-board energy storage.
What would be the advantages from fitting on-board energy storage?
- There would be the savings of electricity by the use of regenerative braking to the batteries.
- Trains could be rescued from the Thames Tunnel, if there was a power failure.
- Hotel power would be maintained, if there was a power failure.
- Trains can be moved in depots and sidings without power.
- Trains would be able to move in the event of cable theft.
- The battery would probably have sufficient capacity to move the train into and out of Euston.
There could be a saving in train operating costs and safety would be improved.
Would It Be Possible For The Bakerloo And Watford DC Lines To Use The Same Trains?
These two lines are very different.
- The Bakerloo Line is a classic London Underground Line with 25 stations and services run by 1972 Stock trains.
- The Watford DC Line is part of the London Overground with 19 stations and services run by Class 710 trains.
Ten stations are shared between the lines, of which only one; Queen’s Park offers level boarding.

- Train Length – NTFL – 113.4 metres – 710 – 80 metres

I feel that the New Tube for London could be designed, so that it could work the Watford DC service.

Queen’s Park And Euston
This map from cartometro.com, shows the route between Queen’s Park and Euston stations.
Note.
- The Watford DC Line is shown in orange.
- Queen’s Park station is to the West of Kilburn High Road station.
- It appears that Watford DC Line trains always use Platform 9 at Euston station.
The route seems to be a self-contained third-rail electrified line into Euston station.
On the subject of electrification between Queen’s Park and Euston stations, there would appear to be a choice between the third-rail system and London Underground’s four-rail system.
But it is rumoured that the New Tube for London will have a battery capability.
As Euston and Queen’s Park stations are only 3.7 miles apart, perhaps the choice would be to use battery power into Euston station, which would remove electrified rails from Euston?

This service wouldn’t be affected as it uses the fast lines between Willesden and Watford.

But what the Bakerloo Line, the Watford DC Line and the Bakerloo Line Extension need is a good dose of holistic design.
Train-Platform Interface On Platform 1 At Willesden Junction
Access to trains at Willesden Junction station can be difficult for some people.
I took these pictures of the access between train and platform for a Bakerloo Line train at Platform 1.
It is a step down from the platform of at least twenty centimetres.
These for a Watford DC Line train are not much better.
Once at this station, an elderly Indian lady in a sari was getting off one of these trains. She shouted something like “Catch me!” and jumped. Luckily, I caught her and it was smiles all round.
Of the ten stations that are shared by both services, it appears that only Queen’s Park has level access for both services.
These stations are an accident waiting to happen.
Kensal Green Junction Improvement
London has a rail capacity problem, for both freight and passenger trains.
This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).
One of the recommendations of the report is to improve Kensal Green junction. It says this about the improvements.
Upgrade of the junction, moving it slightly to the east and realigning the layout, to facilitate faster crossing speeds sufficient for a 3-minute planning margin.
This map from cartometro.com shows the track layout between Harlesden in the West to Kensal Rise station in the East.
Note.
- Harlesden, Willesden Junction Low Level and Kensal Green stations are on the shared tracks of the Bakerloo and Watford DC Lines.
- Willesden Junction High Level and Kensal Rise are stations on the North London Line.
- Kensal Green & Harlesden is a former station on the North London Line, which is shown on the map as dotted platforms.
- Kensal Green Junction is to the West of Willesden Junction High Level station.
- The City Lines, which are shown in black connect the North London Line to the West coast Main Line and the important freight yards at Wembley.
- The black tracks at the bottom of the map are the West Coast Main Line.
This Google Map shows Kensal Green Junction.
Note.
- The railway is the sandy scar across the top of the map.
- The Kensal Green Turnout is in the North-East section of the map.
- The Kensal Green Junction and the City Lines are in the North-West corner of the map.
- The road over the railway in the middle of the map is Wrottesley Road.
These pictures show the Kensal Green Turnout.
And these show Kensal Green Junction and the City Lines.
Note.
- The railway has generous margins.
- The City Lines are electrified.
- The North London Line is electrified.
- The Kensal Green junction appears to be fully electrified.
- All electrification is 25 KVAC overhead.
There would be plenty of space to install a modern efficient junction.
This is said in the Network Rail document about the improvement to Kensal Green Junction.
Kensal Green Junction, just to the northeast of Willesden Junction High Level station on the North London Line, is a key location for the functioning of the orbital routes.
It connects the North London Line to the West Coast Main Line and Wembley Yard, a vital link for cross-London intermodal flows.
Westbound freight trains must cross over the flat junction to access the City lines towards the West Coast Main Line, a conflicting move with any eastbound London Overground or freight services from Willesden Junction High Level. Ensuring these moves can take place as quickly and as smoothly as possible is essential to the efficient use of capacity on the North London Line.
The proposed enhancement would upgrade the junction, moving it slightly to the east and realigning the layout, to facilitate faster crossing speeds.
Currently trains from the City lines (in the eastbound direction) are limited to 10 mph over Kensal Green Junction, while trains towards the City lines (in the westbound direction) are limited to 15 mph.
This scheme would increase speeds through the junction so that trains can safely cross it a
minimum of 3 minutes after a conflicting movement – they currently have to wait at least 4 minutes.Although this is a relatively minor scheme, it could have a significant positive impact on both capacity and performance in the area.
I find the last paragraph very important. So does this improvement scheme offer good value to money?
Could The Junction Be Used By Passenger Trains?
Consider.
- Nothing is mentioned about passenger trains.
- Electric passenger trains are nippier because of better acceleration.
- No scheduled services appear to use the City Lines
- But I did find an empty stock movement from Wembley Sidings to Gospel Oak.
If the junction could be improved would there be any reason to run passenger trains through the junction?
Suppose, High Speed Two, during the rebuilding of Euston station, decided to stop the Watford DC Line services from using Euston station.
If the Class 710 trains of the London Overground could terminate at say Camden Road station, this would give passengers on the Northern part of the Watford DC Line another route to Central London by changing at West Hampstead station for Thameslink or the Jubilee Line or Camden Road station for the Northern Line by walking between the two Camden stations.
I would expect there may need to be some extra crossovers, so that trains from the Watford DC Lines could access the City Lines to get to and from Kensal Green junction.
In Will Camden Road Station Get a Third Platform?, I outlined how Camden Road station could get a third platform, as is also proposed in the LRFS.
But suppose though the existing Platform 2 at Camden Road station were to be diverted into two platforms.
- A Platform 2 East handling services to and from the East.
- A Platform 2 West handling services to and from the West.
That would do nicely.
Conclusion
Improving Kensal Green Junction may improve passenger services, especially if High Speed Two work at Euston means the Watford DC services have to be suspended.

Could The Northern Section Of The Bakerloo Line And The Watford DC Line Be Combined?
The Bakerloo and Watford DC Lines to the North of Queen’s Park station annoy me.
There are two very different classes of trains.
- The 1972 Stock of the Bakerloo Line
- The Class 710 trains of the Watford DC Line
Which are different sizes and ideally need different platform heights for step-free access between train and platform.
Often, you need to step up and down into the trains.
The pictures show a typical steps on Bakerloo Line and Class 710 trains.
They give a new meaning to Mind The Gap.
It would be so much easier, for passengers in wheelchairs or those pushing buggies or trailing heavy cases for there to be no step between train and platform.
I once remarked to a station guy, not in the first flush of youth, as he manhandled a ramp into place, that what he was doing must be the worst part of his job. He smiled and agreed.
Surely in this day and age, we can create a railway, where everything is as efficient as possible.
These are a few of my thoughts.
Could The Two Lines Be Run By A Unified Fleet Of Trains?
If the two lines were to be run using the same trains, this would give advantages.
- All trains could be maintained together.
- Platform-to-train access would be much easier to make step-free.
- Staff would only deal with one type of train.
- A certain amount of automatic train control could be used to increase frequencies.
Obviously, a National Rail-size train couldn’t use the Bakerloo Line tunnels, but a train built for the Underground could use the current Watford DC Line into Euston.
Siemens are designing a New Tube For London and this will be used on the Bakerloo Line.
I suspect, that they could design a train that would easily run into Euston.
Would An Underground Train Provide Enough Capacity Into Euston?
The current trains on both lines have the following capacity and length.
- The 1972 Stock on the Bakerloo Line are 113 metres long and have a capacity of 851 passengers
- The Class 710 trains on the Watford DC Line are 82 metres long and have a capacity of 678 passengers.
Now there’s a surprise! The smaller Underground trains hold more passengers.
This picture shows the spare platform length at Euston, after a Class 710 train has just arrived.
I don’t think capacity or platform length will be a problem!
What Would Be The Frequency Into Euston?
Consider.
- The current Watford DC Line service into Euston uses a double-track line terminating in Platform 9 at Euston station.
- The service frequency on this route, has recently been increased from three trains per hour (tph) to four tph.
- The Overground is soon to start to run six tph on routes with a similar track layout.
I believe that a six tph service could be run between Euston and Watford Junction stations.
What Would Be The Frequency In The Bakerloo Line Tunnel To Elephant & Castle And Lewisham?
Note that I’m assuming an extended Bakerloo Line runs to Lewisham, although, it could run to Hayes station.
Dear Old Vicky (aka the Victoria Line) handles a train every hundred seconds or thirty-six tph.
I can’t see any reason, why all parts of the Watford Junction to Lewisham route can’t be designed to handle this frequency.
If six tph went to Euston, then this would mean the service South of Queen’s Park station would be as follows.
- Up to thirty tph or a train every two minutes between Queen’s Park and Lewisham stations.
- It would connect the National Rail stations of Paddington, Marylebone, Charing Cross, Waterloo, Elephant & Castle, New Cross Gate and Lewisham.
- A high capacity pedestrian link to Crossrail at Paddington, will be ready to open with Crossrail.
- Connections to the Central, Circle, District, Hammersmith & City, Metropolitan, Northern, Piccadilly and Victoria Lines of the Underground.
- Oxford Circus would have a high-capacity cross-platform interchange between the Bakerloo and Victoria Lines, both running in excess of thirty tph.
It would be a much needed capacity upgrade to the Underground.
Would Stations On The Combined Line Be Made Step-Free?
The combined route will have a total of 34 existing stations and four new stations.
I suspect the new stations will be step-free.
Of the existing stations, the following are fully or partially step-free.
- Watford Junction
- Bushey
- Carpenders Park
- Harrow & Wealdstone
- Wembley Central
- Willesden Junction
- Queen’s Park – Scheduled to be made step-free.
- Paddington – Will be step-free, when Crossrail opens.
The Bakerloo Line must be one of the worst lines for step-free access on the London Underground.
But then it has some of the oldest and least-capable trains and has been neglected for decades.
The station most in need of step-free access is probably Oxford Circus, where the Bakerloo and Victoria Lines have a cross-platform step-free interchange.
I lay out ideas for this station in Thoughts On Step-Free Access At Oxford Circus Station.
Upgrading The Lines
I think that Transport for London have a unique opportunity with the upgrading of the Bakerloo Line to Extension From upgrade the line as a series of separate projects, phased to be delivered in a continuous stream, rather than as one big launch, which was tried and failed with Crossrail.
Extension From Elephant & Castle To Lewisham Or Hayes
This project can be built independently, just like the Battersea Power Station Extension of The Northern Line. I detailed the latest thinking on this extension in TfL Moots Bakerloo Line To Hayes.
- It is the only project that needs substantial tunnelling.
- It probably needs a depot to be relocated.
- Lewisham station would need some rebuilding.
- It would need more trains to be delivered before it opens.
It could even be the last project to be delivered, which would allow time for the trains.
Hertfordshire County Council’s Aspiration For A Watford Junction And Aylesbury Service
This article on Ian Visits is entitled Watford Junction Station Could Become A “Super-Hub”.
This is the introductory paragraph.
A new Watford Junction to Aylesbury rail service, along with a new link between Stevenage and Luton are two of the proposals being put forward by Hertfordshire Council.
The proposals are contained in this document on the Hertfordshire County Council web site, which is entitled Rail Strategy.
In TfL Seeks New Procurement Plan For Metropolitan Line Extension, I proposed a service run by Chiltern Railways between Watford Junction and Amersham stations.
The rest of this article is a rewrite of part of that linked post, which explores the possibilities of a service between Watford Junction and Aylesbury stations.
This Was My Original Simple Proposal
I think it would be possible to design a simpler link with the following characteristics.
- Watford station would remain open.
- A four trains per hour (tph) link would run all day between Watford Junction and Amersham stations.
- Stops would be at Watford High Street, Vicarage Road, Cassiobridge, Croxley, Rickmansworth, Chorleywood and Chalfont & Latimer.
No-one would get a worse service than currently and the new stations of Cassiobridge and Vicarage Road, would make rail an alternative for many travellers.
The cross-Watford service would give access to these London services.
- Chiltern at all stations between Croxley and Amersham.
- London Midland at Watford Junction.
- Metropolitan Line at Croxley, Rickmansworth and Amersham.
- Virgin Trains at Watford Junction,
- Watford DC Line at Watford High Street and Watford Junction
The Bakerloo Line at Watford Junction and Watford High Street, could possibly be added, if the line is extended. Which I doubt, it will be!
Hertfordshire is proposing the terminal is Aylesbury, which seems to be a good idea. But I’ll examine that later.
The next few sections, will cover various issues with the route.
New Track
There would need to be new track between Croxley and Watford High Street stations.
Will The New Stations Have Two Platforms?
All proposals have shown new stations on the new track at Cassiobridge and Vicarage Road.
I believe that money can be saved by creating two much simpler stations.
- Only one platform, but probably an island platform with two faces like Watford High Street station.
- No expensive footbridge if possible.
- Only one lift.
Cassiobridge would be more complicated because of the viaduct connecting the line towards Croxley station.
This visualisation shows the viaduct and the location of Cassiobridge station.
Cassiobridge station will be behind the trees towards the top-right of the image.
Would The New Track Be Single Or Double-Track?
There is space for double-track and the two ends of the route are already electrified double-track.
But surely the viaduct shown above would be much more affordable, if it were to be built for only one track!
Trains would need to pass at places East of Croxley station, but then if the line was double-track through and to the East of Cassiobridge station, trains could pass with impunity.
Consider.
- The Borders Railway looks to have too much single-track
- The Barking Riverside Extension is being built with a double track.
Too much single-track is often regretted.
Why Four Trains Per Hour?
Four trains per hour (tph) is becoming a standard, as it encourages Turn-Up-And-Go behaviour from travellers.
It also fits well with keeping the four tph Metropolitan Line service to Watford station, as this could give a same platform interchange at Croxley station.
Would The New Track Be Electrified?
The only part of the route that is not electrified is the about three miles of new track between the Watford Branch and the Watford DC Line.
All current electrification is either third-rail or to the London Underground standard. and any future electrification would probably be to the London Underground standard, so that S Stock can work the route.
I believe that the Class 710 trains will have a limited onboard energy storage capability, which could enable the trains to bridge the cap in the electrification between Watford High Street and Croxley stations.
How much would not electrifying the new track save?
How Long Will A Journey Take From Amersham Or Aylesbury To Watford Junction?
Consider.
- Amersham to Croxley takes about 30 minutes, but it does involve a change to a bus.
- The Overground takes three minutes between Watford Junction and Watford High Street stations.
- Chiltern Railways achieve a twelve minute time between Amersham and Rickmansworth.
I suspect that a modern train like one of London Overground’s Class 378 trains could do the journey in a few minutes under half-an-hour.
As Amersham to Aylesbury takes about sixteen minutes, that looks like a trip between Aylesbury and Watford Junction would take about forty-five minutes.
Amersham Or Aylesbury?
My original plan used Amersham, as it has a turnback facility.
But Aylesbury looks to have space as this Google Map shows.
It should also be noted that the forty-five minute journey time between Aylesbury and Watford Junction stations, would give a two hour round trip, with relaxed fifteen minute turnround times.
This would allow time to top-up the batteries.
What Class Of Train Could Be Used?
Four-car Class 378 trains or the new Class 710 trains would be ideal. As the Class 378 train is out of production, it would have to be Class 710 trains or something similar from Bombardier. But other manufacturers might have a suitable train.
Battery power would be required, but that is becoming a standard option on metro trains like these.
How Many Trains Would Be Needed?
If the trains could do an Out-and-Back journey in an hour, then four trains would be needed to provide a four tph service.
A two-hour time would need eight trains.
Will The Link Have Any Other Services?
I have seen to plans to use the line for any other passenger or freight services.
Will There Be Infrastructure Issues At Existing Stations?
As all of the trains, I’ve mentioned and the London Underground S Stock trains, share platforms all over North West London, the answer is probably no, with the exception of a few minor adjustments to signs and platforms.
Croxley Station
Croxley station would be unchanged.
But in addition to the 4 tph between Baker Street and Watford, there would be 4 tph between Watford Junction and Amersham.
Platform 1 would handle.
- Baker Street to Watford
- Amersham to Watford Junction
Platform 2 would handle.
- Watford to Baker Street
- Watford Junction to Amersham
This would mean that if the trains alternated, the maximum wait for a connection would be about 7.5 minutes.
What I feel would be the two most common connections, would just involve a wait on the same platform.
I suspect that those, who timetable trains, would come up with a very passenger-friendly solution.
Watford Station
A property developer once told me, that the most profitable developments, are those where a railway station is involved.
So would the development of the extension involve a rebuild of Watford station to provide the following?
- A modern future-proofed station, with all the capacity that might be needed in the next forty years or so.
- Appropriate housing or commercial development on top of the new station.
- Sensible amounts of parking for travellers.
With four tph to and from London in the basement, it would surely be a profitable development.
Watford Junction Station
Watford Junction station has four bay platforms 1-4, that handle the three tph service on the Watford DC Line.
At stations like Clapham Junction, Crystal Palace, Dalston Junction, Highbury and Islington and New Cross, single platforms handle four tph with ease for London Overground services.
This means that handling four tph to Amersham in addition to current services would not be difficult.
The only work, that I think should be done, is make sure that these platforms are long enough to take two of the future Class 710 trains working as an eight-car train.
There could even be two platforms left for Bakerloo Line services, if it were to be decided, that these services would go to Watford Junction.
Elton John Plays Vicarage Road Stadium
This or some football matches at Vicarage Road Stadium, would be the biggest test of the Link.
Note the following.
- Some stations like Watford High Street can already handle longer trains than the hundred metre long, five-car Class 378 trains they currently do.
- Some stations like Croxley can handle the 133 metre long S Stock trains used on the Metropolitan Line.
So to future-proof the Link for massive one-off events would it be sensible to make the platforms long enough for eight-car trains or two Class 710 trains working as a pair?
Benefits
The benefits of this approach are as follows.
- Watford station keeps its current service to London.
- Watford gets a four tph link across the South of the town, serving the Shopping Centre, the Hospital and the Stadium.
- Amersham or Aylesbury to Croxley stations get a link to the West Coast Main Line.
- It could be built as a single track line without electrification.
- Trains to run the services could be more easily available.
- Simple island platform-based stations could be built at Cassiobridge and Vicarage Road.
In addition, Chiltern Railways, London Midland, London Overground and Underground, all gain a feeder railway bringing travellers to their services to and from London.
Cost Savings
Note.
- Transport for London needs cost savings on this project.
- Redevelopment of Watford station as a station with oversite development could raise a lot of money.
- The Croxley Link could be built as a single-track link without electrification and run initially using battery-electric trains.
I also feel, that building the line this way would deliver it earlier, thus improving cash-flow.
The simple link would need at the minimum.
- A single- or double-track railway without electrification between Croxley and Watford High Street stations.
- Two stations with island platforms at Cassiobridge and Vicarage Road
- A viaduct to connect Cassiobridge station to the Watford Branch.
- Some Class 710 trains or similar.
If skates were worn, the link could probably open in 2025.
More Frequent Trains And A New Station For The London Overground
The title of this post, is the same as that of this article on IanVisits.
This is said.
In a statement, the government agreed to requests for £80.8 million from the GLA to support transport upgrades so that 14,000 homes can be built along the East London Line.
Upgrades include.
- New Bermondsey station, which was originally to be called Surrey Canal Road, will be built.
- A second entrance will be built at Surrey Quays station.
- Frequency between Dalston Junction and Clapham Junction stations will be increased from four trains per hour (tph) to six tph.
- Frequency between Highbury & Islington and Crystal Palace stations will be increased from four tph to six tph.
The frequency upgrades will mean twenty tph between Dalston Junction and Surrey Quays stations, or a train every three minutes as opposed to the current three minutes and forty-five seconds.
A few thoughts follow.
Surrey Quays Station Upgrade
Ian’s article says this about the new entrance at Surrey Quays station.
The very cramped Surrey Quays station gets a second entrance, which will run under the main road and be based on the north side, where the shopping centre car park is today. That avoids crossing two busy roads, which can take some time if you’re waiting for the lights to change.
This Google Map shows the station and the car park of the Shopping Centre.
These are my pictures, taken at and around the station.
Traffic is bad and the subway suggested by Ian’s wording will be very welcome.
Collateral Benefits At New Cross Gate
New Cross Gate station will be one of several stations along the East London Line to see benefits in service frequency and quality.
The train frequency on East London Line services will rise from eight tph to ten tph.
But this is not all that should or could happen.
- The service between Highbury & Islington and West Croydon stations could rise from four tph to six tph.
- This would mean that New Cross Gate would have a twelve tph service to and from Whitechapel, which in a year or so, will have Crossrail connections to Canary Wharf, Bond Street, Paddington and Heathrow.
- Southeastern should be getting new higher-capacity, higher-performance and possibly longer trains to replace their elderly trains into London Bridge.
- Charing Cross station is redeveloped into a higher-capacity, cross-river station, to allow more trains.
- Digital signalling, as used on Thameslink will be extended to cover all trains through New Cross and New Cross Gate.
- The Docklands Light Railway to Lewisham will get new and higher-capacity trains.
- Southeastern Metro services could go to the London Overground.
Could this all mean that the East London Line, Southeastern and Crossrail will more than hold the fort until it is decided to build the Bakerloo Line Extension?
The Bakerloo Line Extension
This map from TfL shows the route of the Bakerloo Line Extension.
If and when the Bakerloo Line Extension is built, New Cross Gate will surely become a major transport hub.
If you look at the current and proposed stations on the Southern section of an extended Bakerloo Line, you can say the following.
- Paddington will get a step-free pedestrian link between Crossrail and the Bakerloo Line.
- Charing Cross will benefit from more Southeastern Metro services into the main line station.
- Waterloo will benefit from more Southeastern Metro services through the attached Waterloo East station.
- Elephant & Castle station will benefit from more Thameslink services through the attached main line station.
- New Cross Gate will benefit from more Southeastern Metro and East London Line services through the station.
- Lewisham will benefit from more Southeastern Metro services through the station.
But there are no interim benefits for the blue-mauve area, that will be served by the proposed Old Kent Road 1 and Old Kent Road 2 stations.
In addition, is there a need to add capacity between the New Cross area and Lewisham? Southeastern improvements will help, but the Bakerloo Line Extension will do a lot more!
Except for these two stations, is there a reason to build an extension to the Bakerloo Line, as train services between Charing Cross, Waterloo East and New Cross and Lewisham will be significantly increased in frequency, reach and quality?
A Bakerloo Line Extension Redesign
Whatever happens to the Bakerloo Line, the following should be done.
- New walk-through trains running at a higher-frequency on the current route.
- Major access improvements and better connection to main line services at Elephant & Castle, Waterloo East, Charing Cross and Willesden Junction stations.
- A radical reorganisation North of Queen’s Park station, in conjunction with the Watford DC Line and the proposed West London Orbital Railway.
This would improve the current line, but it would do nothing for those living where the extension will go!
So why not do what is happening to the Northern Line at Battersea and create a short extension to the Bakerloo Line that serves the areas that need it and one that can be extended in the future?
- You could argue, that the extension to Lewisham is short and it could be extended to Hayes and other places.
- I also think, that the route goes via New Cross Gate, as that is one of the few sites in the area, from where a large tunnel could be built.
Ideally, what could be needed is a high-capacity public transport link from Elephant & Castle and Greenwich and/or Lewisham via the Old Kent Road, New Cross Gate and New Cross.
The Germans, the Dutch and others wouldn’t mess about and would run trams along the road, but that would go down with the locals like a lead West London Tram.
So it looks like some form of extension of the Bakerloo Line is the only way to go.
Consider.
- Two-platform terminal stations at Brixton and Walthamstow Central handle up to thirty-six tph on the Victoria Line.
- New Cross Gate and New Cross stations are about five hundred metres apart.
- Double-ended stations like Knightsbridge on the Piccadilly Line and Kings Cross on the Victoria Line work very well.
I would look at building a double-ended Bakerloo Line station deep underneath New Cross Road.
- It would be connected by escalators and lifts to the existing stations at New Cross Gate in the West and New Cross in the East.
- Provision would be made to extend the line further to either Greenwich or Lewisham.
- New Cross and Lewisham already have a high-frequency connection of six tph.
- The whole extension could be built from the single tunnelling location on the Sainsbury’s site at New Cross Gate.
- There would be no necessity for any works at Lewisham station.
It would probably need more services to be run between New Cross and Lewisham.
Current Services Between New Cross And Lewisham
Southeastern currently runs these services between New Cross and Lewisham.
- London Cannon Street and Slade Green via Sidcup
- London Cannon Street and Orpington via Grove Park
- London Cannon Street and Hayes
All services are two tph.
Extending The East London Line Service South From New Cross
New Cross is served by the only short service on the London Overground; the four tph between Dalston Junction and New Cross stations.
So could this East London Line service be extended South to serve Lewisham to increase services between New Cross and Lewisham?
This map from carto.metro.free.fr shows the lines at New Cross station.
Note how the double-track East London Line, shown in orange, arrives from Surrey Quays station arrives in the North-Western corner of the map, becomes a single-track and then goes under the main lines before going into the bay platform D.
This Google Map shows the same area.
The London Overground track is clearly visible.
Could extra track be added, to enable the following?
- Southbound trains could join the main line and stop in Platform C
- Northbound trains could leave the main line after stopping in Platform A and go towards Surrey Quays station.
If this is possible, then it would give a four tph service between Dalston Junction and Lewisham, with an important stop at Whitechapel to connect to Crossrail.
Lewisham doesn’t have the space for a terminal platform, but there would appear two possible terminals South of Lewisham.
- Hayes – Journey time to and from Dalston Junction would take around 53 minutes.
- Orpington – Journey time to and from Dalston Junction would take around 50 minutes.
Both stations would make ideal terminals.
- They have bay platforms for terminating the trains.
- Round trips would be a convenient two hours.
- Eight trains would be needed for the service.
- New Cross will have the same four tph to and from Dalston Junction as it does now!
- Lewisham and Dalston Junction would have a four tph service that would take 27 minutes.
The service could even be split with two tph to each terminal.
Will the Extended Services Need To Replace Other Services?
Currently Hayes has these current Off Peak services.
- Two tph to Cannon Street via London Bridge
- Two tph to Charing Cross via London Bridge
I would expect that if digital signalling is applied through the area, that the extra services could be added to Hayes and Orpington as decided.
An Improved Hayes Line
Transport for London and various commentators always assume that the Bakerloo Line will eventually take over the Hayes Line.
This will or could mean the following.
- Passengers used to a full-size train looking out on the countryside and back gardens through big windows, will have to get used to a more restricted view.
- Platforms on the Hayes Line will need to be rebuilt, so that two different size of train will be step-free between train and platform.
- The service could be slower.
- The ability to walk through an increasingly pedestrianised Central London to and from Cannon Street, Charing Cross and London Bridge will be lost.
- Loss of First Class seats. which will happen anyway!
I think that passengers could want to stick with the current service.
The only reason to allow the Bakerloo Line Extension to take over the Hayes Line, is that it would allow another four tph to run between Lewisham and London Bridge. But digital signalling could give the same benefit!
But what if the Overground muscled in?
The Hayes Line could take up to four tph between Dalston Junction and Hayes, via Lewisham and New Cross, which would give these benefits.
- Increased capacity on the Hayes Line.
- An excellent connection to Crossrail, which would give a better connection to the West End, Liverpool Street and Heathrow.
- Better connection to the Eastern side of the City of London and Canary Wharf.
- It could free up four tph between New Cross and London Bridge.
- Same-platform interchange between Southeastern and East London Line services at Lewisham and New Cross.
There would need to be these changes to the infrastructure.
- A new track layout at New Cross.
- Installation of digital signalling.
The latter will happen anyway.
Times To And From Crossrail
Times to and from Whitechapel, with its Crossrail connection are.
- Lewisham – 17 minutes
- Hayes – 44 minutes
- Orpington – 41 minutes
The current service between Orpington and Farrington, which also will connect to Crossrail, takes 52 minutes.
Penge Interchange
Although, this has not been funded, I think that this new interchange could be very much in Transport for London’s plans.
I discuss the possible Penge Interchange station in Penge Interchange.
It’s certainly something to watch out for, as it could improve connectivity by a large amount.
The View From The Dalston Omnibus
For decades, Dalston had a terrible reputation and then came the Overground, which changed everything.
There are now these combined devices from the two Dalston stations.
- Eight tph to Stratford
- Four tph to Richmond via Willesden Junction
- Four tph to Clapham Junction via Willesden Junction
- Four tph to Clapham Junction via Surrey Quays
- Four tph to Crystal Palace via Surrey Quays
- Four tph to New Cross via Surrey Quays
- Four tph to West Croydon via Surrey Quays
There is also a useful eight tph connecting service between Dalston Junction and Highbury & Islington.
In the next couple of years, these developments should happen.
- Services on the East London Line will be increased with an extra two tph to Clapham Junction and Crystal Palace.
- Services on the North London Line will be increased to cope with overcrowding. As the Dalston Junction and Highbury & Islington connecting service will be going to ten tph, it would seem logical that the North London Line service should match this frequency.
- Crossrail will open and Dalston will have a twenty tph connection to its services at Whitechapel.
Dalston needs better connections to either main line terminal stations or their interchanges a few miles out.
Currently, Dalston has very useful connections to the following main interchanges.
- Stratford for the Great Eastern Main Line.
- Clapham Junction for the South Western Railway and Southern services.
- Richmond for Windsor and Reading services.
- Whitechapel will provide a link to Crossrail.
- In addition the planned update at Norwood Junction will give better connection to services to Gatwick, Brighton and other services to the South of Croydon.
Better interchanges are needed with services to the North and the South East of London.
Extending the Dalston Junction and New Cross service to Hayes or Orpington via Lewisham could greater improve the train service from Dalston, by providing interchange to services fanning out into and beyond South East London.
Conclusion
I am drawn to these two conclusions.
- The Bakerloo Line should be extended via two new Old Kent Road stations to a double-ended terminal station in New Cross with interchange to both New Cross Gate and New Cross stations.
- The New Cross branch of the London Overground should be extended through Lewisham to Orpington and/or Hayes.
My preferred destination for the London Overground service could be Hayes, as this would surely help to free up paths through Lewisham and London Bridge.
