Will Clapham Junction Station Get A Platform 0?
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 build a Platform 0 at Clapham Junction station. It says this about that that platform.
Creation of additional bay platform capacity at the northern end of Clapham Junction station, for the use
of London Overground WLL services.
This map from cartometro.com shows the track layout as the orange tentacles of the London Overground approach Clapham Junction station.
Note.
- The West London Line approaches Clapham Junction station through Imperial Wharf station.
- The South London Line approaches Clapham Junction station through Clapham High Street and Wandsworth Road stations.
This second map from cartometro.com shows the track layout of the current two Overground platforms at Clapham Junction station and how the third one will fit in.
Note.
- It appears that there are crossovers to allow trains from either South or West London Lines to enter any of Platforms 0, 1 or 2.
- A typical bay platform can turn four trains per hour (tph) or possibly six tph, if the signalling is tip-top.
These pictures show the current state of Platform 0 at Clapham Junction station.
And these show Platforms 1 and 2 at Clapham Junction station.
The current two-platform system seems to work well.
Clapham Junction Station Is A Super-Interchange
Clapham Junction is already a super-interchange on the London Overground with lots of services to Central and Outer London and the wider South of England.
The London Overground probably needs more super-interchanges on its circular route around London.
- Whitechapel and Stratford, which are one stop apart on Crossrail, could develop into one in East London.
- As it grows, Old Oak Common, will develop into one in West London.
Other super-interchanges could develop at Croydon, Hackney (Central/Downs) and West Hampstead.
Network Rail’s Reasons For The New Platform
I’ll start with some information.
Current Overground Services
Current Overground services are as follows.
- 4 tph – Stratford via Willesden Junction
- 4 tph – Dalston Junction via Surrey Quays
The total of 8 tph, is generally easily handled by two platforms, unless something goes wrong.
Future Overground Services
It is expected that in the future services could be as follows.
- 6 tph – Stratford via Willesden Junction
- 6 tph – Dalston Junction via Surrey Quays
As I regularly use the service between Dalston Junction and Clapham Junction to get a connection to places like Portsmouth and Southampton, I know at least one regular traveller, who is looking forward to the increase in frequency.
But there could be another London Overground in the future.
In Gibb Report – East Croydon – Milton Keynes Route Should Be Transferred To London Overground, I wrote how in his report, Chris Gibb recommended that this hourly service should be transferred to the London Overground.
This is said in the Network Rail document about Platform 0 at Clapham Junction station.
The longstanding proposal for the creation of additional bay platform capacity at the northern end of Clapham Junction station, for the use of London Overground West London Line services, is supported by this strategy.
The scheme would reinstate the disused former platform 1 to create a newly designated ‘Platform 0’, adjacent to the present platforms 1 and 2.
This intervention has been recognised as key to long-term growth on the West London Line by several previous pieces of work for both Network Rail and Transport for London, which have consistently concluded that additional platform capacity at Clapham Junction is needed, if TfL’s aspiration to increase the WLL Overground service to 6 trains per hour is to be met.
Capacity analysis for the LRFS has reaffirmed that the desire to operate this level of service throughout the day cannot be achieved with a single bay platform.
Although this scheme would clearly be of direct benefit to the London Overground passenger service, the positive impact it would have on the capacity and performance of the WLL overall means that it is also very much in the interest of freight that Platform 0 be delivered. Without a new bay platform, the main alternative means to increase Overground train frequencies involves the use of platform 17 at the far end of the station, where freight and GTR trains pass through towards the BML. This is a sub-optimal solution for both freight and passenger operations.
Note.
- Platform 0 will share an island platform with Platforms 1 and 2, so there will be short level walks between trains.
- Platform 1 and 2 are already fully accessible, so Platform 0 will be as well.
The report feels that increasing passenger and freight services are often two sides of the same coin.
Questions
I have some questions.
Would Three Platforms Be Enough To Handle Twelve tph?
As two platforms seem to handle eight tph, at most times in the present, I suspect the answer is in the affirmative.
Would Three Platforms Be Enough To Handle Thirteen tph?
This would be needed, if the Milton Keynes service were to be transferred to the Overground and it used Clapham Junction station as a Southern terminus.
If it still went through Clapham Junction station to Croydon, then it would probably use Platform 17, as it tends to do now!
I do suspect that three platforms will be enough, as otherwise the LRFS would be proposing something else.
What Will Be The Length Of The New Platform 0?
Under Future Proposals in the Wikipedia entry for Clapham Junction station, this is said.
In a Network Rail study in 2015, it was proposed that platform 0 could reopen for 8-car operations of the West London Line.
An eight-car platform would allow the current eight-car Class 377 trains, that work the Milton Keynes service to use the platform.
Note that as an eight-car Class 377 train is 163.2 metres long, a platform that will accomodate this train, will be long enough to accomodate a five-car Class 378 train, which is only 102.5 metres long.
But should the platform be built long enough to handle two Class 378 trains working as a pair?
This Google Map shows Platform 1 and the current state of the future Platform 0 at Clapham Junction station.
Note.
- a five-car Class 378 train is standing in Platform 1.
- There are some minor obstructions along Platform 0.
I don’t think it would be impossible to create an eight-car Platform 0. Although, Platforms 0 and 1 might need to be extended by perhaps ten or twenty minutes towards London.
Does The Milton Keynes and Clapham Junction Service Need 110 mph Trains?
I have talked to several drivers, who drive trains on the four 125 mph lines out of London and some have complained about slower 100 mph trains, that get in their way and slow them down.
If the drivers get miffed, I suspect the train operating companies are more annoyed.
But over the last few years, the following has happened.
- Heathrow Express have replaced 100 Class 360 trains with 110 mph Class 387 trains on the Great Western Main Line.
- East Midlands Railway will be running 110 mph Class 360 trains to Corby on the Midland Main Line.
- West Midlands Trains will be replacing 110 mph Class 350 trains with 110 mph Class 730 trains on the West Coast Main Line.
- Great Northern run 110 mph Class 387 trains to Cambridge and Kings Lynn on the East Coast Main Line.
I wouldn’t be surprised to see 110 mph trains running between Milton Keynes and Clapham Junction, as they would just be following a sensible practice to increase capacity.
Conclusion
I have no problems with creating a new Platform 0 at Clapham Junction, but suspect that faster trains would be needed for the Milton Keynes and Clapham Junction, that would use it.
Work Appears To Have Already Started On Platform 0
With the installation of the all-important site hut and the fact that there were several engineers around with laser-measurement tools, I suspect that work is already underway to prepare everything for the construction of Platform 0 at Clapham Junction station.

A London Overground Replacement For Southern’s East Croydon And Milton Keynes Service
In July 2017, I discussed this suggestion by Chris Gibb in Gibb Report – East Croydon – Milton Keynes Route Should Be Transferred To London Overground.
In an article, in the July 2019 Edition of Modern Railways, , which was entitled ‘710s’ Debut On Goblin, this was this last paragraph.
On the West London Line, TfL is curremtly working with the Department for Transport on options for the devolution of services originally suggested in Chris Gibb’s report on the Govia Thameslink Railway franchise, which could lead to ‘710s’ being deployed here.
It made me think, that further investigation was called for.
An Apology
I apologise, if you think I’m repeating myself.
What The Gibb Report Says
The Gibb Report, says this about the current service between East Croydon and Milton Keynes Central stations.
I believe there is an option to transfer the East Croydon – Milton Keynes operation to TfL and it’s London Overground concession in 2018.
TfL may decide to change the service, for example by not running it north of Watford Junction, or running it to an alternative southern destination other than East Croydon. They could also develop the combined West London line service to better match available capacity to demand.
They would have a number of crewing and rolling stock options, but should be able to operate the service more efficiently than GTR in the longer term, without the involvement of Selhurst.
Selhurst TMD is the depot in South London, where the current Class 377 trains are based.
A few of my thoughts.
The Trains
Using Class 710 trains as suggested in the Modern Railways article, would surely offer a suitable crewing and rolling stock option for the route, if they were based at the convenient Willesden TMD, where the fleet of up to twenty-five dual-voltage Class 710/2 trains are stabled.
The Northern Terminus
Chris Gibb suggested the service might not go past Watford Junction.
I think that could be difficult.
- The longitudinal seating of the Class 710 train, is probably not suitable for outer suburban services North of Watford.
- East Croydon to Watford Junction takes 69 minutes, which is not a good journey time to create an efficient service.
It would also appear to be tricky for a train to transfer between the West London Line and the Watford DC Line.
This map from carto.metro.free.fr shows the complicated track layout in the Willesden Junction area.
Note.
- The two Willesden Junction stations, labelled High Level and Low Level.
- The Watford DC Line, which is shown in black and orange, passing to the North of Willesden TMD. and through the Low Level station.
- The four tracks shown in black are the West Coast Main Line, with Watford to the West and Euston to the East.
- The North London Line to Richmond and the West London Line to Clapham Junction splitting at Wilesden High Level Junction.
The current service between East Croydon and Milton Keynes, is only one train per hour (tph) and uses a succession of flat junctions to take the slow lines to and from Watford.
This is not a good operational procedure and I suspect Network Rail and various train operators, would like to see it discontinued.
So if trains in a new London Overground version of the service, don’t go up the Watford DC Line or the West Coast Main Line, where do they turn back?
Note the siding to the East of the High Level platforms, which is labelled Willesden Junction Turnout.
This is regularly used to turnback London Overground services on the West London Line.
I feel that London Overground will be turning their replacement service in Willesden Junction High Level station.
Current train services at the station include.
- For passengers, who want to go further North, there is a good connection to the Watford DC Line for Wembley Central, Harrow & Wealdstone and Watford Junction stations.
- The Watford DC Line can also take you to Euston.
- The Bakerloo Line between Stonebridge Park and Elephant & Castle via Central London.
- Frequent North London Line services between Stratford and Richmond.
The station has kiosks, coffee stalls, toilets and waiting rooms.
There are certainly worse places to change trains.
The Southern Terminus
Obviously, existing travellers on the route would like to see as few changes as possible.
East Croydon station must be a possibility for the Southern terminus, as it is the currently used.
But East Croydon is a busy station and perhaps it is not a convenient station for trains to wait in the platform.
On the other hand, West Croydon station offers some advantages.
- The station has a long bay platform, which might be long enough for nine or ten cars.
- There is a separate turnback siding.
- It has space to add another bay platform, but this may have been sold to a developer.
- It already has a four tph London Overground service to Highbury & Islington station.
- Using West Croydon avoids the crowded lines to the North of East Croydon station.
It is also managed by London Overground, so the landlord would be co-operative.
How Many Trains Would Be Needed For A West Croydon And Willesden Junction Service?
West Croydon station has two possible routes, that trains could take to Willesden Junction.
- Via Norwood Junction and Clapham Junction in 55 minutes.
- Via Selhust and Clapham Junction in 45 minutes.
These times mean that a two-hour round trip between West Croydon and Willesden Junction should be possible.
Trains required for various frequencies would be as follows.
- One tph – Two trains.
- Two tph = Four trains.
- Four tph – Eight trains.
They would need to be dual voltage Class 710/2 trains, as are now running on the Gospel Oak to Barking Line.
Compare the figures with those for the current East Croydon and Milton Keynes service, which needs four pairs of four-car trains for an hourly service.
What Would Be The Frequency?
I think one, two and four tph are all possibilities!
One tph
One tph would be a direct replacement for the current service. But is it enough?
Services at West Croydon could probably share the bay platform with the existing Highbury & Islington station service.
Two tph
Two tph could be a compromise frequency.
Two tph could probably still share the current bay platform with the Highbury & Islington service.
Four tph
Four tph would be a full Turn-Up-And-Go service,
- It would probably be London Overground’s preference.
- It would give a very passenger-friendly eight tph between Willesden Junction and Clapham Junction stations.
- The two services would call at opposite sides of Clapham Junction station.
- It would give a four tph link between Croydon and High Speed Two.
- Westfield wouldn’t mind all the extra shoppers at Shepherds Bush!
But there could be downsides.
- The service could need an extra bay platform at West Croydon.
- Would it be possible to turn four tph at Willesden Junction?
- Will the train paths be available through South London.
But four tph would probably would be London Overground’s preference.
It will be interesting to see the reasons, why Transport for London choose a particular frequency.
A Trip Between Imperial Wharf And East Croydon Stations
Today, I took a trip between Imperial Wharf and East Croydon stations at around 11:30.
- The train was two four-car Class 377 trains working as an eight-car train.
- After Clapham Junction it wasn’t very busy.
- I was in the last car, which was empty, except for myself.
I came to the conclusion, that an eight-car train was too much capacity for the Southern section of the journey.
I suspect that Transport for London have detailed passenger estimates for this route, so they should be able to determine the frequency and length of replacement trains required.
The Upgraded Norwood Junction Station
In Major Upgrade Planned For Norwood Junction Railway Station, I talked about a plan to upgrade Norwood Junction station.
The idea behind the upgrade is to improve connectivity and capacity in the crowded Croydon area.
If the West Croydon and Willesden Junction service, was routed via Norwood Junction station, the upgraded station would give easy access to both East and West Croydon stations.
Conclusion
I’ve always liked Chris Gibb’s suggestion of the transfer of the service between East Croydon and Milton Keynes stations to the London Overground and I can now start to see flesh on the bones!
At the present time and until better data is available, I think the replacement service should be as follows.
- The Northern terminus should be Willesden Junction.
- The Southern terminus should be West Croydon station, where there are good tram and train connections.
- The route would be via Shepherds Bush, Kensington Olympia, West Brompton, Imperial Wharf, Clapham Junction, Wandsworth Common, Balham, Streatham Hill, West Norwood, Gipsy Hill, Crystal Palace and Norwood Junction.
- Going via Gipsy Hill, rather than the current route via Selhurst, would give access to the connectivity at Norwood Junction.
- The frequency should be four tph.
- Trains will be four- or five-car Class 710 trains.
The benefits would be as follows.
- The rail hubs of Clapham Junction, Norwood Junction, West Croydon and Willesden Junction would be connected together by a Turn-Up-And-Go service.
- The proposed four tph service would need eight Class 710 trains, whereas the current one tph service needs eight Class 377 trains. Would this be better value?
In the future with a connection to High Speed Two in the Old Oak Common area, the benefits would increase.
- There would be a simple interchange with High Speed Two.
- South London from Clapham to Croydon, would get a direct service to High Speed Two.
- There would also be a better connection to Heathrow Airport and other rail services through Old Oak Common.
I think that the connection to High Speed Two trumps everything else.
Gibb Report – East Croydon – Milton Keynes Route Should Be Transferred To London Overground
The Gibb Report, says that the East Croydon – Milton Keynes route should be transferred to the London Overground.
By 2020 London will have two high-capacity and two medium-capacity cross-London heavy rail routes, backed up by several cross-London Underground Lines.
- Central Line – 30+ trains per hour (tph)
- District Line – 20+ tph
- Crossrail – 24 tph
- East London Line – 20 tph
- Jubilee Line – 30+ tph
- Metropolitan Line – 20+ tph
- Northern Line – 30+ tph
- North London Line – 16+ tph
- Piccadilly Line – 30+ tph
- Thameslink – 24 tph
- Victoria Line – 30+ tph
One line is missing from this list; the West London Line, which has a rather pathetic four tph between Clapham Junction and Willesden Junction stations.
Until Southern got embroiled in their Driver Only Operation dispute, there used to be a very useful one tph service between East Croydon and Milton Keynes Central stations.
The Gibb Report says this about the service.
I believe there is an option to transfer the East Croydon – Milton Keynes operation to TfL and it’s London Overground concession in 2018.
TfL may decide to change the service, for example by not running it north of Watford Junction, or running it to an alternative southern destination other than East Croydon. They could also develop the combined West London line service to better match available capacity to demand.
They would have a number of crewing and rolling stock options, but should be able to operate the service more efficiently than GTR in the longer term, without the involvement of Selhurst.
Selhurst TMD is the depot in South London, where the current Class 377 trains are based.
I think that this is a good proposal for the following reasons.
- As was seen on the Chingford Branch Line, London Overground have a reputation for making a good fist of taking over services that need improvement.
- As the Gibbs Report says, the combined West London Line service could be developed.
- I have net quite a few people, who use this West London Line route to get to and from events at Wembley stadium.
- The service could call at Old Oak Common station to connect to Crossrail and HS2.
- A variant of London Overground’s new Class 710 trains, could probably work the shortened route, as either four or eight-car trains.
- The Class 710 trains could be based at the convenient Willesden TMD, along with the rest of the fleet.
Being practical, a service of just two tph would give a train every ten minutes on the West London Line.
The Current Service
The current service is supposed to stop at the following stations.
- Bletchley
- Leighton Buzzard
- Tring, Berkhamsted
- Hemel Hempstead
- Watford Junction
- Harrow & Wealdstone
- Wembley Central
- Shepherd’s Bush
- Kensington (Olympia)
- West Brompton
- Imperial Wharf
- Clapham Junction
- Wandsworth Common
- Balham
- Streatham Common
- Norbury
- Thornton Heath
- Selhurst
Note.
- Stations between Watford Junction and Clapham Junction, already have a substantial Overground presence.
- London Overground already run three tph on the Watford DC Line between Euston and Watford Junction stations.
But would this be the ideal route?
The Northern Terminal
The West Coast Main Line is very busy and stations between Watford Junction and Milton Keynes are well-served by London Midland and Virgin Trains.
So would it be sensible to continue a slower local service North of Watford Junction?
It should also be remembered, that Southern introduced the original service to give better access to Gatwick Airport. Surely, this need is now satisfied by services from Clapham Junction and East Croydon.
As Watford Junction station probably has platform capacity, surely Watford Junction should be the Northern terminal
Could The Service Use The Watford DC Line?
If this were possible, this must surely give advantages, especially if Watford Junctio is the Northern terminal.
- Dual-voltage Class 710 trains could work the route.
- The service level on the Watford DC Line would be increased.
- There would be no problem accessing the bay platforms at Watford Junction station.
- There would be no requirement for any paths on the West Coast Main Line.
I think the answer to whether the Watford DC Line could be used at the present time is that trains going from the West London Line to Watford Junction must use the West Coast Main Line.
This map from carto.metro.free.fr shows the lines around Willesden Junction..
As it is all railway land, I suspect that the connection can be created.
The one problem, is that some of the Watford DC Line is shared with the Bakerloo Line.
But as the Bakerloo Line is being extended to the South and the Northern end will probably be improved, then surely creating an optimal solution to the Watford DC line, the Bakerloo Line and Overground services to Watford, makes a lot of sense.
The Southern Terminal
Various stations have merits and problems to be used as the Southern terminal for the service.
Clapham Junction
Clapham Junction would appear to have a strong case, but London Overground had enough problems squeezing in their current services.
As the station is now substantially step-free and has typically three tph to Gatwick Airport, Clapham Junction offers a good route to the airport.
Balham
Balham has been used as a terminal in the past and connects to the Northern Line. If redeveloped for Crossrail 2, it could be a possibility.
Steatham Common
Streatham Common could be developed as a major interchange and if this happens, then surely is is a possibility.
East Croydon
East Croydon would have a strong case, as it is a busy and well connected station, but there probably isn’t a suitable platform.
I think that any station South of East Croydon is probably too far.
My money would be on the new interchange station at Streatham Common, with Balham as an alternative.
Schedules And Trains
I estimate that a train doing a return journey between Watford Junction and Streatham Common would take under three hours, using the Watford DC Line. This would mean that three trains would be needed for an hourly service and six trains for a half-hourly service.
Conclusion
Transferring the East Croydon – Milton Keynes route to the London Overground looks feasible.
