Level Boarding Included In Rail Innovation Funding Competition
The title of this post, is the same as that of this article in Railway Gazette.
This is the introductory paragraph.
Innovate UK has opened the latest calls for grant funding proposals under the First of a Kind programme, which supports the demonstration of innovative technologies to give them a better chance at being deployed by railway companies.
What annoys me about boarding trains (and some buses for that matter!), is how variable it is.
- Trains in East Anglia, Merseyside and Switzerland are particularly good, but then they have the common Stadler factor.
- Will the Newcastle Metro and the Glasgow Subway be as good?
- Some European countries, including Germany, could do much better!
- Once at Leipzig, I helped four hefty Germans lift a guy and his wheel-chair out of the bottom-deck of a double-deck train.
- In London, the Docklands Light Railway, the Elizabeth Line and some parts of the Overground are acceptable, but there is need for improvement.
- Southeastern, including the HighSpeed is particularly dodgy and I need help at some stations like Clapham Junction and Lewisham.
- Bank has a notorious platform on the Central Line.
- Perhaps the worst in London are some stations on theBakerloo Line, where it shares with the Watford DC Line.
All passengers on buses and trains deserve the best access that designers and bus and train manufacturers can devise.
In one incident, a slight, elderly Indian lady in a sari, was having difficulty getting down from an Overground train on the Watford DC Line at Willesden Junction station.
I was the only person on the platform, so I called out. “Can You Jump?”
Which she did and landed safely on her feet! I caught her and it was smiles all round!
I suspect she’d done that before.
So is one idea to give all passengers, lessons in jumping on and off buses and trains?
Seriously though, could Lego devise a large-scale engineering version of their product, that could be used to create steps and humps, which could be glued together for strength.
Alternatively, 3D printing could be used to create gap-fillers.
I think this challenge from Innovate UK will bring forward some good solutions.
Extending The Elizabeth Line – Adding Ladbroke Grove Station To The Elizabeth Line
There is a Wikipedia entry for Ladbroke Grove railway station, which starts with this paragraph.
Ladbroke Grove is a proposed railway station in London, England on the Crossrail Route between Old Oak Common and Paddington. This is not part of the internal route and would be added at a later stage. Locals want the station to be called Portobello Central to serve the nearby Portobello Market. It was originally called Kensal.
The Wikipedia entry also gives these details of two proposals for a Ladbroke Grove station on the Elizabeth Line.
Kensington and Chelsea Council has been pushing for a station at North Kensington / Kensal, just to the east of the Old Oak Common railway station site, off Ladbroke Grove and Canal Way, as a turn-back facility will have to be built in the area anyway. Siting it at Kensal Rise, rather than next to Paddington itself, would provide a new station to regenerate the area. Amongst the general public there is a huge amount of support for the project and then-mayor of London Boris Johnson stated that a station would be added if it did not increase Crossrail’s overall cost; in response, Kensington and Chelsea Council agreed to underwrite the projected £33 million cost of a Crossrail station, which was received very well by the residents of the borough. Transport for London (TfL) is conducting a feasibility study on the station and the project is backed by National Grid, retailers Sainsbury’s and Cath Kidston, and Jenny Jones (Green Party member of the London Assembly).
The plans were resurrected by Boris Johnson in 2016.
In March 2017, it was announced that TfL was considering a Crossrail station in Kensal Green, on the site of a former gasworks, and it would be between Old Oak Common and Paddington.
This map from cartometro.com shows the railway lines to the West of Paddington.
Note.
- The Elizabeth Line is shown in purple.
- Ladbroke Grove rube station is not close to the Elizabeth Line.
- Kensal Green tube station is not close to the Elizabeth Line.
But we do know this about the future Old Oak Common station.
- It will be served by Elizabeth Line services between Central London and Heathrow Airport.
- It will be served by High Speed Two services between London Euston and the North of England and Scotland.
- It will be served by Great Western services between London Paddington and the West of England and Wales.
- It will be served by North London Line services betweeen Stratford and Richmond.
- It will be served by Heathrow Express services between London Paddington and Heathrow Airport.
From the map, it looks unlikely that the Hammersmith & City Line will be able to serve Old Oak Common station.
However, it might be possible that Euston and Old Oak Common could be served by Watford DC Line services, which called at either Old Oak Common or Kensal Greeen.
A link between Euston and Old Oak Common, would give all stations on the line access to High Speed Two and Heathrow with a change at Old Oak Common.
Some Euston suburban services could stop at Old Oak Common for access to High Speed Two and Heathrow.
The Watford DC Line which is very self-contained could become a comprehensive feeder line for High Speed Two and Heathrow.
Kensal Green Station
I took a trip to Kensal Green station and took these pictures.
Note.
The station handles two heights of trains on single-height platforms.
Some of the stairs are not the best.
There is no step-free access.
There are six lines through the station and there may be scope for more platforms.
If ever there was a station that needed a makeover it is Kensal Green.
Conclusion
I doubt that the Hammersmith & City Line could be connected to the Elizabeth Line to the West of Paddingt9n.
But I do feel that the Watford DC Line could be developed into a comprehensive link between Euston and Old Oak Common satiations.
Why The Elizabeth Line Must Be Extended To Ebbsfleet International
There are various plans to link the Elizabeth Line to Ebbsfleet International.
In Elizabeth Line To Ebbsfleet Extension Could Cost £3.2 Billion, I showed this map from the Abbeywood2Ebbsfleet consultation.
There doesn’t appear to be too much new infrastructure, except for a proper connection between Northfleet and Ebbsfleet stations. References on the Internet, say that the similar-sized Luton DART connection at Luton Airport, cost around £225 million.
The Elizabeth Line connects to the following.
- Bond Street
- Canary Wharf
- City of London
- Farringdon for Thameslink
- Heathrow Airport
- Old Oak Common for High Speed Two
- Liverpool Street station
- Oxford Street
- Paddington station
- Slough for Windsor
- Tottenham Court Road for the British Museum, Oxford Street, Soho, Theatreland and the Underground.
- West End of London
- Whitechapel for the Overground and Underground
For many people like me, the Elizabeth Line at Ebbsfleet will provide one of the quickest ways to get to and from European trains.
High Speed Two Services
This diagram shows High Speed Two services, as they were originally envisaged before Phase 2 was discontinued.
Note.
- Trains to the left of the vertical black line are Phase 1 and those to the right are Phase 2.
- Full-Size trains are shown in blue.
- Classic-Compatible trains are shown in yellow.
- The dotted circles are where trains split and join.
- In the red boxes routes alternate every hour.
- Was Lancaster chosen as it’s close to the new Eden Project Morecambe?
Click on the diagram to enlarge it.
Destinations served by the current foreshortened High Speed Two or High Speed Two Lite will be.
- Birmingham Curzon Street
- Birmingham Interchange
- Carlisle
- Carstairs
- Crewe
- Edinburgh Haymarket
- Edinburgh Waverley
- Glasgow Central
- Lancaster
- Liverpool Lime Street
- Lockerbie
- Macclesfield
- Manchester Airport
- Manchester Piccadilly
- Motherwell
- Oxenholme
- Penrith
- Preston
- Runcorn
- Stafford
- Srockport
- Stoke-on-Trent
- Warrington Bank Quay
- Wigan North Western
- Wilmslow
That is twenty-five stations.
I would add these extra stations.
- Bangor
- Blackpool
- Chester
- Holyhead
- Llandudno Junction
- Wrexham
Note.
- These extra six stations would make High Speed Two, a line for more of the people.
- Because the Eastern leg is cancelled, the paths that would have served that leg can be used to provide services for the West of the country.
The East of the country could be served by updating the East Coast Main Line.
The Development Of Eurostar
Consider.
- Eurostar and Thalys have now merged and I can see them providing extra direct services between London and Europe.
- Bordeaux, Cologne, Frankfurt and Geneva have been mentioned as possible destinations.
- Most of the new destinations, will be served by extending current services from Amsterdam, Brussels and Paris appropriately.
But to cope with the extra numbers of passengers, there will have to be extra passenger capacity at St. Pancras and/or Ebbsfleet International.
High Speed Two And Continental Services
Currently, if you want to go from the North of England or Scotland to the Continent, you do one of the following.
- Take a train to King’s Cross and walk across to St. Pancras International.
- Take a train to St. Pancras and walk to the International section of the station.
- Take a train to Euston and walk or take a bus, taxi or Underground to St. Pancras International.
Note.
- Passengers from North Wales take the Euston route.
- Some passengers will take an Elizabeth Line train to Farringdon and then take Thameslink to St. Pancras International.
- Passengers arriving at Paddington on Heathrow Express will probably take a taxi to St. Pancras International.
- Passengers arriving at Paddington on a budget will probably take the Underground to St. Pancras International.
For Londoners and those travellers, who know London well, the routes to St. Pancras International, are not to bad but they could be better.
If the current foreshortened High Speed Two or High Speed Two Lite finishes at Old Oak Common station, passengers will have to use the following routes for their onward journey.
- Elizabeth Line
- Great Western Railway – local services.
- Heathrow Express
- North London Line of the London Overground, or whatever the Mayor at the time calls it.
If the full High Speed Two or High Speed Two Lite finishes at Euston station, passengers will have to use the following routes for their onward journey.
- Avanti West Coast
- Circle, Hammersmith & City and Metropolitan Lines
- London North Western – local services
- Northern Line
- Victoria Line
- Watford DC Line of the London Overground, or whatever the Mayor at the time calls it.
These routes will be in addition to those at Old Oak Common station.
There will be two routes between High Speed Two and St. Pancras International station.
- Passengers arriving at Old Oak Common will take an Elizabeth Line train to Farringdon and then take Thameslink to St. Pancras International.
- Passengers arriving at Euston will walk or take a bus, taxi or Underground to St. Pancras International.
I am not sure that either route will have enough capacity, if High Speed Two attracts a large number of passengers.
Extend High Speed Two To Euston
I believe that this is essential, as it improves the connectivity greatly, at the bottom end of High Speed Two, as several Underground Lines will be connected to High Speed Two.
Extend The Elizabeth Line from Old Oak Common To Ebbsfleet International
I believe this too is essential, as it gives the North of England and Scotland, the connection to the Continent that they need.
There could be cross-platform connections at both Old Oak Common and Ebbsfleet International between the Elizabeth Line and the high speed lines.
Conclusion
Politicians should stop the dithering and act to give the UK, the rail connection it needs up and down the country and to the Continent.
Jobs, Homes And The Economy: Bakerloo Line Upgrade And Extension To Be Transformational For London
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is the sub-heading.
The government has been urged to use the upcoming spring budget to commit to upgrading and extending the Bakerloo line after a new impact assessment found its effects could be transformational.
These three paragraphs introduce the article.
The impact assessment – commissioned by Central London Forward, a partnership of 12 central London boroughs – finds that such a move would boost the economy, unlock new homes, create new jobs, and more.
The upgrade would centre around new trains and signalling, while the extension would take the terminus to Lewisham in the first phase, and eventually to Hayes – adding 14 new stations.
The impact assessment concludes that the extension and upgrade of the Bakerloo line would create 9,700 jobs, 190,000 square metres of commercial floorspace, as well as generate £1.5bn of GVA.
The article is a must-read and eloquently puts the case for the Bakerloo Line Extension.
I have a few thoughts.
A Loop At Brixton For The Victoria Line
This has been proposed and the Wikipedia entry for the Victoria Line has this paragraph.
Proposals have been made to extend the line one stop southwards from Brixton to Herne Hill, a significant interchange in south London providing access to Kent, Blackfriars, London Bridge and Sutton. The latter station would be on a large reversing loop with a single platform removing a critical capacity restriction eliminating the need for trains to reverse at Brixton and provide a more obvious route for passengers who look for the nearest tube station before any other transport options.
I like this idea.
- It will make it easier to run the full frequency of 33 trains per hour (tph) between Brixton and Walthamstow Central stations.
- Loops at Heathrow and Liverpool seem to work very well.
- A single-platform with platform-edge doors has a high level of safety.
- Only one tunnel boring machine (TBM) would be needed.
- Large lifts could be used between the surface and the platform.
- It is a more affordable option.
But perhaps most importantly, I am sure, the loop could be built whilst other services at Brixton and Herne Hill were running almost without disruption, as services did at Kennington, whilst the Battersea Extension of the Northern Line was built.
A Loop At Elephant And Castle For The Bakerloo Line
I have spent forty years involved in project management, writing software for project managers and generally listening to some of the thoughts and experiences of some of the best engineers from all over the world.
One common thread, which is best illustrated by how the size of lift possible increased in the North Sea in the 1970s, is that as time has progressed machines have got bigger and more capable, and the techniques of using them has improved immeasurably.
The Crossrail tunnel boring machines (TBM) make those used on the Jubilee Line extension or the Channel Tunnel look like toys. But not only are the TBMs bigger and faster, they have all the precision and control to go through the eye of the smallest needle.
If we look at the proposals for the Bakerloo Line Extension, there have been several differing ideas. Some envisage going under Camberwell and in others the trains terminate on the Hayes line.
Transport for London (TfL), obviously know the traffic patterns, but do we really want to take the chance of say connecting the Hayes line to the Bakerloo and then finding that it’s not the best solution?
What we should do is augment the services in the area, by providing a good alternative transport route, that links to some of the traditional rail lines to give even more flexibility. We certainly shouldn’t repeat the grave mistake that was made at Brixton in the 1960s by not connecting the Victoria line to the surface rail lines.
This is Transport for London’s indicative map of the extension.

I have reason to believe that the Northern Line Extension may be being built as an extension to the Kennington Loop.
So could we design the Bakerloo Line Extension as a loop starting and finishing at Elephant and Castle calling at important stations?
A possible route could be.
- Elephant and Castle – Interchange with Northern Line and National Rail including Thameslink
- Old Kent Road 1 – Proposed on Map
- Old Kent Road 2 – Proposed on Map
- New Cross Gate – Interchange with London Overground and National Rail
- Lewisham – Interchange with Docklands Light Railway and National Rail including Hayes Line
- Catford Bridge – Interchange with Catford station and National Rail including Hayes Line and Thameslink
- Peckham Rye – Interchange with London Overground and National Rail
- Camberwell – Interchange with National Rail including Thameslink
- Elephant and Castle
The advantages of this simple design are.
- The tunnel would be excavated in one pass by a single TBM.
- The line could be deep under any existing infrastructure.
- Most stations would be simple one-platform affairs, with perhaps only large lifts and emergency stairs, to give unrivalled step-free access for all from the street to the train. Surely lifts exist, that are large and fast enough to dispense with escalators.
- For safety, passenger convenience and flows, and other reasons, the stations could have two entrances, at opposite ends of the platform.
- The simple station entrances would be much easier to position on the surface, as they wouldn’t need to be much bigger than the area demanded by the lifts.
- A single loop would only need half the number of platform edge doors.
- At stations like New Cross Gate, Lewisham, Catford and Peckham Rye the lifts would surface within the confines of the existing surface stations.
- The route has interchanges with the Brighton Main Line, East London Line, Hayes Link, Thameslink and other services, so this would give lots of travel possibilities.
- Trains do not need a terminal platform, as they just keep going on back to Elephant and Castle.
- The loop would be operationally very simple, with no points to go wrong. TfL have aspirations to run twenty-seven trains per hour on the Bakerloo and a simple reversing loop , which would mean the driver didn’t have to change ends, must certainly help this. It would probably be a lot more difficult to get this capacity at the northern end of the line,where Harrow and Wealdstone doesn’t have the required capacity and the only possibility for a reversing loop would be north of Stonebridge Park.
- Elephant and Castle would need little or no modification. Although it would be nice to have lifts to the Bakerloo Line.
- Somewhere over two billion pounds has been quoted for the extension. A single loop with simple stations must be more affordable.
The main disadvantage is that the loop is only one-way.
But making even part of the loop two-way would create all the operational difficulties of scheduling the trains. It would probably be better, less costly and easier to make the trains go round the loop faster and more frequently.
But if a passenger went round the loop the wrong way and changed direction at Elephant and Castle that would probably only take a dozen minutes or so.
Alternatively, I’m sure some New Routemasters would step up to the plate and provide service in the other direction between the stations.
Future Rolling Stock For The Bakerloo Line
This has a section in the Wikipedia entry for the Bakerloo Line, where this is said.
In the mid 2010s, TfL began a process of ordering new rolling stock to replace trains on the Piccadilly, Central, Bakerloo and Waterloo & City lines. A feasibility study into the new trains showed that new generation trains and re-signalling could increase capacity on the Bakerloo line by 25%, with 27 trains per hour.
In June 2018, the Siemens Mobility Inspiro design was selected.[ These trains would have an open gangway design, wider doorways, air conditioning and the ability to run automatically with a new signalling system.[35] TfL could only afford to order Piccadilly line trains at a cost of £1.5bn. However, the contract with Siemens includes an option for 40 trains for the Bakerloo line in the future. This would take place after the delivery of the Piccadilly line trains in the late 2020s.
A loop from Elephant and Castle with a train every 2¼ minutes, is not going to be short of passengers.
The Catford Interchange
Catford and Catford Bridge stations are not far apart.
In An Opportunity At Catford, I talked about what could be done to create a full step-free interchange, which could be connected to the Bakerloo Line loop underneath.
Would It Be Possible For The Bakerloo And Watford DC Lines To Use The Same Trains?
I answered this question in a post with the same name and this was my 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.
The current trains on the Watford DC Line would be moved to the London Overground. They could be ideal for the future West London Orbital Railway.
Would There Be Advantages In Creating The West London Orbital Railway And Extending The Bakerloo Line As One Project?
Consider.
- The two lines will have an interchange station at Harlesden, which will need to be rebuilt.
- The current trains on the Watford DC Line could be cascaded to the West London Orbital Railway.
- As new trains are delivered to the Piccadilly Line, some of the current trains could be cascaded to the Bakerloo Line.
- Major work for the Bakerloo Link Extension includes a new tunnel, updated signalling and at least seven underground stations.
- Major work for the West London Orbital probably includes track refurbishment, new signalling and updated stations.
I believe that with good project management, that if these two lines were to be created together, this would be advantageous.
Conclusion
I have only outlined how the two projects might be done together.
But I am absolutely certain, that someone with full knowledge of both projects could build the two at a very affordable cost.
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.
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
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 passenger density and speed are closer than I thought they’d be.
- I’m sure Siemens can design a longer and faster train if required for the Euston service.
I feel that the New Tube for London could be designed, 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.
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 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.
Conclusion
A common fleet used by the Bakerloo and Watford DC Line would appear to give advantages.
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.
