Further to JB's report on the ELLX Phase Two extension from Surrey Quays to Clapham Junction, let's go for a photographic guided tour of the end of the line at Clapham Junction where passengers will be able to change between the East and West London Lines of London Overground.

With Battersea Power Station and the massive gas holder that loomed over Battersea Park station in the background, this 1947 view of the city end of Clapham Junction clearly shows from left to right the sets of lines that run through Clapham Junction
- The double tracks of the West London Line coming up from Latchmere and Longhedge Junction running into platforms 1 and 2.
- The three tracks of the LSWR's Windsor Lines from Waterloo running through platforms 3,4,5 and 6
- Carriage siding head shunts for the Clapham yard lying between the Windsor and LSWR main lines
- Four tracks from Waterloo forming the main line to Wimbledon and the South West
- Four tracks for Victoria forming the LB&SC's mainline to Balham, Croydon and Brighton.
- Just behind the electric multiple unit seen on the right, the West London's line connecting to the Brighton line emerges from crossing under all of these tracks past the Pig Hill sidings
In particular note the point ladder running diagonally from the Latchmere and Longhedge Lines on the left that connects with all of the L&SWR Windsor lines and terminates at the entrance to Clapham Yard and Park Sidings.

Our thanks to Moe Quette for allowing us, as ever, to dip into the Affleck's Palace that is his visual history collection, for this picture.
The West London line connection from Latchmere and Longhedge junction into platform 1 and 2 was later singled and the track lifted from platform 1, which was built on an extension to the embankment that the rest of the station is built of. This was known as the Banana Arches. The track bed in platform 1 was subsequently used as a signalling and point work communications channel. The difficulty of moving this equipment together with the poor condition of the Banana Arches is the reason behind the decision to redevelop the existing platform 2 to cope with both WLL and ELL trains.
This picture shows a 313 unit approaching Clapham Junction over the single track chord and one of the signalling relay boxes on the left.

Our thanks and copyright acknowledgement to Mark Hewitt for the use of this picture
In preparation for the arrival of the ELL which will run from Longhedge Junction under the all the mainline tracks, this link has now been recently redoubled from Latchmere Junction.
Our friend, Flierfy provides the next three pictures, to whom our thanks and copyright acknowledgements
The first shows the aggressively steep and narrow staircase down to the subway, complete with handily placed discarded Red Bull can, (no doubt left by some thoughtful passenger to enable those of us, who count in cans, to judge the scale of the stairs). The staircase emerges next to the ticket office on the Northern side of the Station where there is a local bus interchange. Until recently these steps presented a significant challenge to the elderly and disabled.

The next picture shows the platform from the other direction revealing the elegant canopy and the jarring steel fence at the edge of Platform 1. It would be nice if this fence could be replaced by something similar to the staircase railings, more in keeping with the overall aesthetic when the platform is rebuilt, but alas Boris; aesthetes are not made of money and Network Rail's philistines will probably not care.

The next picture shows the approximate position of the end of platform two after it is truncated to form a bay for WLL terminators.

Dave Curran provides us with the next three pictures to whom our thanks and copyright acknowledgements

Hopping over the fence Dave shows the overgrown condition of the track bed in Platform 1. All of that moisture retaining vegetation has not doubt contributed to the decay of the metal trough forming the Banana Arches.
The next picture shows the S&T boxes occupying the former track bed. Relocation would be difficult and hence expensive.

Moving on to footbridge, Dave's picture shows platform 2 on the left and platform 3 servicing the Up Windsor slow line on the right.

As the diagram above (helpfully proved by George) helps illustrate, the plan for Clapham Junction is to build out over the western end of the track in platform 1 to form a new platform face next to the middle track in this picture. This was the Middle siding and formed part of the head shunt for the Kensington sidings to the west of the station shown in Dave's next picture.

Clapham Yard carriage sidings can be seen on the far left of this picture with the four tracks of the LSWR line to Putney and Windsor running through the centre of the shot. There have been proposals by local MP's for the ELL trains to be extended over the Windsor Lines and thence to Wimbledon via East Putney. This would require the replacement of a previously demolished flyover at Point Pleasant Junction just beyond Wandsworth Town and an increase in the signalling and point work complexity to enable down ELL trains to cross over the Windsor lines.
To the right lay the Kensington Sidings which in days of yore provided a playground for the many types of tank engine used on empty carriage duties in an out of Waterloo. Here they shunted with much clanking and tooting and biffing, the Southern Railway's signature braked parcels vans known, to those of us riddled with acne at the time, as GUV's.
These sidings could come into life again as a valuable stabling resource for London Overground. In the event of perturbation on both the ELL and WLL, the sidings allow trains to temporarily be stabled and re-sequenced. This will avoid them being blocked at signals on what will be very busy routes through South and West London.
Stannah have recently supplied lifts from all of the platforms at Clapham Junction to the footbridge (surely one of the best places in London to watch trains go by) at the western end of the station which, together with the new entrance, make the station accessible those who are disabled, pilot baby buggies or, perchance, carry Mwmbwlian levels of avoirdupois. There is a neat example of their handiwork beyond the footbridge steps on Platforms 1 & 2

Our thanks and copyright acknowledgement to Stannah Lifts for the use of this picture
The new entrance on Saint John's Hill restores an access route that had not been used for over half a century, The project, was funded by Network Rail, Department for Transport, South West Trains, Wandsworth council and Transport for London, includes new ticketing facilities, travel information screens and passenger toilets in a fully refurbished ticket hall, together with new shops. Outside the building a taxi and car pick-up and drop-off point is being created and cycle racks for up to 72 bikes are being installed.

The new entrance provides a step-free route into the station, making it fully accessible to those with reduced mobility. This marks the completion of the £10.5million "Access For All" scheme at the station, which has also seen nine lifts installed between the over bridge and all platforms.
The new entrance will also provide an alternative way into the station for those coming from St John's Hill, helping to reduce congestion significantly in the subway and main entrance - although as the above picture shows it is at this stage lightly used even at peak times as yet. (Of course, having written this, I realise that by drawing attention to the ease of use of the new kiss and ride drop off point might be self-defeating if too many follow the author's example and use it.)
Having praised access on the south side, I wish I could say the same for the north side of the station. Unfortunately the lifts only run from the platform to the over bridge and not down to ground level. The gradients from the subway can be described as fearsome. Disabled passengers entering from the north entrance on Grant Road face a trundle to the south side of the station in order to access the footbridge via the Saint John's Hill entrance and then have to navigate back to the north side, having to sometimes weather the tides of humanity in the subway and on the bridge.
It seems a pity that the lads from Stannah were not asked to tag an extra lift to access the western end of the Grant Road.
The next three pictures show the construction of the Banana Arches. These are in very poor condition. Although not clearly evident in these pictures, there is significant corrosion in the downpipes and the track bed trough. There is also clear damage to the retaining wall, as water penetrating the walls through the corroded metal works expands when it freezes leaving voids in the mortar.





These are then exploited by Buddleia Davidii, "the Butterfly Bush", which having escaped from domestic gardens is a great coloniser of dry open waste or old masonry. The odd wisp that can be seen in the pictures will soon grow into a dense thicket. Its roots penetrate the mortar and further allow water to penetrate the brickwork. Subsequent freezing and thawing prise the bricks apart, helping the Buddleia to penetrate further and a vicious circler arises...
Together with Japanese Knotweed, Buddleia is listed as an invasive species in many areas of London. It is frequently seen beside railways in London having gained a pandemic hold by growing on Second World War bomb sites. The end of steam ended the fire hazard to line side vegetation. British Rail was able to relax the need for length men to keep line-side vegetation under strict control. The regime of benign neglect that manifested itself in virtually perpetual maintenance holidays that British Rail was obliged to impose on its infrastructure have taken their toll. It will be surprising if a degree of remediation will be required before too long.
Castles in the Air
No doubt Clapham Junction (and its ELLX/WLL platforms) will change further in the future, so I annex, purely to mobilise the comments of our readers, some points to think on as to what future options might be:
- To extend the over the track space left by the old platform. By springing a cantilevered platform surface off of the existing platform it would be possible to avoid loading the dodgy Banana Arches. Although, they will undoubtedly need some attention. This arrangement would also mean that the S&T cabling could continue to occupy the trough
- To install the missing lift connecting the platform with the Grant Road Ticket Office
- To reinstate the Kensington Sidings as emergency stabling and turn round facilities. This would allow the system to enjoy some resilience so that in the event of an outbound delay to either the WLL or ELLX (SLL) inbound services could continue to run.
- If the extension of the WLL to Wimbledon ever took place a connection at the west end of the platform from the Windsor Up Slow line would enable all northbound WLL services to operate from the new platform, offer cross platform interchange with the ELLX (SLL). Apart that is for the Brighton line services from Croydon which operate via platforms 16 and 17
Postscript
One of the good things about writing for London Reconnections is that it has such a rich editorial domain. There is always something worthwhile to write about. Our articles however always benefit from pictures and for that there is often an issue of being the right man or woman, in the right place at the right time with their camera held a-clicko. This article and many others would not have been possible without the help of the diverse group who contribute to Flickr. I am always overwhelmed by their kind responses to allow me to use their material. So to all our chums on Flickr (you know who you are) thank you.
My thanks also to the Clapham Junction Action group who keep a close eye on all developments at the station
Surely the idea is to build out the west end of platform 2 over the platform 2 track, to reach the central disused track.

Any more info on the MPs that have suggested the extension of LO to East Putney? Its one of those no brainers given how bad Wandsworth town is in the morning.
ReplyDeleteLO to East Putney is a ridiculous idea, unless you replace the old up side ramp and flyover and run it bidirectionally.
ReplyDeleteTrains would otherwise have to cross the four SWT tracks on the level. There's no way this could be funded - and I doubt there'd ever be a business case as there's a perfectly sensible alternative route using the district line to interchange with the WLL at West Brompton...
Not only is the Buddleia invasive, but 'r's are too
ReplyDelete"helping the Buddleia to penetrate further and a vicious circler arises..."
Proof reading aside, my understanding of the plan for platform 2 were the same as the first commenter's. I've modified George's diagram to reflect my understanding of the bay platform plan (as opposed to the half-Cambridge option depicted in the post).
Clapham Junction platforms 2a and 2b
If it is as I understand it, then unless there is pointwork on the approach connecting both tracks, a train in platform 2a that is unable to leave for any reason would suspend the West London Line south of Imperial Wharf - surely not a sensible long-term plan?
Trains from the WLL and SLL will be able to reach either platform, even with a train stuck in the prospective 2A, 2B can be accessed from both routes, though presumably 8 tph in total would be difficult.
ReplyDeleteThere would be distinct advantages if during perturbations trains could run through beyond 2B - especially if they could also return through P3
There will be point-work to access P2A from the SLL and P2B from the WLL (e.g. both Latchmere curves are bi-driectionally signalled), so services can be diverted to the 'other' platform (albeit with some possible delays).
ReplyDeleteApropos Brighton Yard entrance and the much published comment that this has been disused for over 50 years. I am sure that I was using this entrance as a teenager in the early 1960`s. I always felt it closed in 1966. Also, whilst the 1980`s building were constructed around the subway in the mid 1980`s, the Brighton Yard entrance was open for many months as the main entrance was closed. - tickets were sold from a temporary building in the carpark, which was earlier a temporary branch of Barclays Bank whilst it was being rebuilt.
ReplyDeleteI attended a meeting at `arry`s Bar at The New Den in early March. The Network Rail chappy showed me a Gant Chart that said the new platform at Clapham Junction was going to be contructed October 2011 to January 2012.
Your map looks wrong to me. I was told that the existing platform 2 would be extended to the centre road at the country end of Clapham Junction.
I was at CJ yesterday and had to exit to transfer from an Oystercard journey to a ticketed one. I was impressed by the new stairs and lifts and bought my ticket at the Brighton Yard entrance. It was in the evening peak, and the new entrance was quite busy by the standards of any station in the suburbs, but really quiet for CJ. I had to wake the ticket office man to sell me one. Very nice. I forsee Network Rail taking the place over and strengthening the bridge to squeeze in loads more 'retail opportunities'.
ReplyDeleteInteresting post, thanks. I agree it would be good to see Kensington Sidings used. Building capacity for resilience will become increasingly important across the network, and also because the WLL and ELL services will rapidly grow in popularity and frequency.
ReplyDeleteThe rerrangements at Platform 1/2 will be short-term fixes only. As frequencies and demand increase they will have to rebuild on the Grant Rd side and recreate Platform 1, and the Kensington Sidings will be used for reversing.
I can't see the Up Line to Point Pleasant Junction being brought back without some integrated thinking with the Northern extension to Battersea and then to Clapham and beyond, along with new capacity for the Windsor Lines. Extending the ELL service may be worthwhile (not the WLL), but I can't see it justifying the necessary grade-separated junction for a Down ELL Line west of Clapham Jn.
However, it would be interesting to touch on the broader plans for Clapham Jn, particularly given that the RUS raises the need for additional tracks for the SWML.
Despite the upgrade, Clapham Jn remains a dogs breakfast of a station, with potential to be a much better hub and interchange. The redevelopment plans that fell through in 2009 traded a rebuild in return for two tall towers on the SE side. But is there potential to explore alternative development options that ramp over part of the station, for instance along St Johns Hill, or across the throat to the Grant Rd side?
Lord save us from a construction deck over Clapham Junction ! A lovely monster soaring canopy over the lot would preserve the Victorian querkery while a few extra bridges beneth that would provide space for some real facilities (rather than in the supercrush down there in the subway)
ReplyDeletestephenc -Concerning the extension to Wimbledon

There was an adjournment debate in Westminster Hall on the 27th June 2007 when the issue was first raised.
Chris M - Much as I am tempted to claim as did Colin Firth as King George VI in the King's Speech that I have to throw the odd typo in so that you know it's me - that would not alas be true. Mwmbwls fwmbwls - apologies.
Anonymous at 18.48 the connection between the Windsor and the Latchmere/Longhedge lines already exists. See the 1947 picture of the point ladder of the city side of Clapham Junction. This is IIRC due to be modified according the the London and South East RUS with the Clapham yard access being removed but not the Windsor lines access. Replacement of the up ramp at Point Pleasant would be necessary hence my suggestion of a link at country end of platform 2. I agree that crossing four tracks to access the down Windsor slow would be a pain in the signalling neck but that was the political aspiration at the time and may be it still is. The MP's were focussed on getting a link from Wimbledon to Straford in time for the Olympics.They obviously did not grasp the implications of a Conservative Mayor facing a Labour Government Transport Minister.
In my original draft I did include a diagram of my wishlist for Clapham Junction but somehow this has got lost in the wash. I too was showing platform 2 built out to the centre road - but at that stage I was speculating.
Steven - I was unable to track down just who had got the final track diagram for the new arrangements and we tended to be brushed off when we asked which I assumed was linked to underlying debates about costs and who is going to pay etc.
The LO to East Putney concept requires three main changes. 1) A flyover west of CJ (no-one would suggest running flat across all the lines. 2) Reinstate the up flyover at Point Pleasant. 3) Change the usage of down fast and down slow so that slow trains are on the south side. It *may* also require the platform 1 reinstatement discussed as difficult in the post.
ReplyDeleteThe LO trains would share the Windsor tracks through Wandsworth Town (about a mile), but those lines are not at trains-per-hour capacity. I think that extending the ELLX (SLL) to East Putney makes more sense than the WLL. While few people would take the train all the way to Peckham or Shoreditch, it would allow Wandsworth Town commuters the ability to actually get on a train, even if just to CJ. From CJ they would then have lots of other options to catch an onwards train. My understanding is that for at least 45 minutes in the morning it is currently impossible to board at Wandsworth Town, suggesting that this is needed and would be used.
I'd also note that the District is known to be overloaded too, so if the trains could reach Wimbledon, that would help there too. Doubters should note that the new RUS suggests Crossrail 2 down the SW main line, thus some other solution will be needed to relieve the District (which Crossrail 2 was going to do). LO to East Putney or Wimbledon is therefore an obvious counterpart to Crossrail 2.
@stephenc
ReplyDeleteCrossrail 2 doesn't have to take over part of District to relieve it. If the SWML already transits through central London, and has a lot fewer stops than the District before reaching it, why would anyone bother to change at Wimbledon??
COST too much?
ReplyDelete[ To have P1 in use, and Point Pleasant N flyover rebuilt ]
Well scrap Boris' idiotic, dangerous, unsightly and useless cable-car, and spend the money on this, instead!
If this project were in Germany or France they would simply demolish the Banana Arches and build something stronger instead of tip-toeing around crumbling infrastructure and letting it rot. But no, we are British and we build new railways held together with sellotape because we never quite have enough money to do a job properly!
ReplyDeleteSo am i correct to think that if the train at platform 2b needs to leave before the train at platform 2a it will simply just use the points to go ahead of it.
ReplyDeleteNot been able to work it out before.
@Anonymous 23:35. I agree that Crossrail 2 should not go via East Putney, as you say no-one at Wimbledon or south west of there would use it as it wouldn't be quick enough. However, I don't believe that a direct to Wimbledon Crossaril 2 would noticably relieve the District, whereas a link for Wimbledon Park, Southfields and East Putney to CJ would. Exactly how much of a relief it would create requires analysis.
ReplyDeleteBTW, does anyone know of a good source for estimating the civil engineering cost of railway investment?
Surely with a reduction in Olympia services, new trains with greater capacity and a new ATO signalling system there will be a short and medium term boost on that branch? By 2018 the District line will be able to carry 25% more passengers than now.
ReplyDeleteIn the longer-term (i.e. next decade onwards) you could take off one of the other branches, maybe the richmond one, with that old plan of the central line running down it consider that the Ealing stub will be redundant once crossrail comes (and there are options for others to take that short bit like the NW-W London light rail corridor for example).
@Zeke
ReplyDeleteIf the layout is as shown in the diagram in the article, yes.
However I don't think that is the planned layout (see my first comment). If my diagram is correct then there is no conflict.
Aye - Chris' Diagram is clearer so I'm going to update the article to include it.
ReplyDeleteRather off-topic but Overground related. This weekend's Athletics Grand Prix gives you the opportunity to walk through the old ticket hall at Crystal Palace. I was there today and staff were directing Oyster users through the gates in the 80s "conservatory" and paper ticket holders through the old exit. Apologies again for going off-topic bit I know the long-term reopening of the old CP ticket office has been discussed here before.
ReplyDeleteBut Greg what if the Cable car is a success? I know, complain that they should have built a bigger system.
ReplyDeleteIs there any scope for the Overground to share the lines with the District Line from West Brompton to Wimbledon?
ReplyDeleteFrom what I can gather, it is difficult to add more District Line service during the rush hour because they have to merge with trains from Richmond, etc. If a couple of train per hour were Overground trains that carried on up the WLL line you would get an increase in capacity.
Sheperds Bush would provide an interchange onto the Central Line and buses; this may even be a better place to change for some people.
In a similar vein, could some SLL Overground trains bypass Clapham Junction and carry on up the WLL to terminate at Kensington Olympisa?
@Bob
ReplyDeleteI don't know about the capacity of that bit of the District line, but I don't think there is much if anything available on the West London Line, so it might only be possible with a diversion of some of the existing services, which probably wouldn't go down well south of West Brompton. There is also the issue of reversing capacity at Willesden Junction. I don't think WLL trains can reach the low-level bay in passenger service?
There is currently no junction between the District and WLL at West Brompton and the gradients wouldn't make constructing one easy.
I too recall using the "Brighton Yard" st Johns Hill entrancr to CJ in the early eighties when the subway was being done up, so it has certainly not been disused for fifty years. (Very convenient it was for me, as it reduced my journey from front door to platform by 50%!)
ReplyDeleteLike others, my understanding is that the new platform (to be numbered "2") is to be built out over the country end of No 2 road, so that the middle siding (between existing No 2 and No 3 roads) will become a through platform, genderally to be used by terminating ELL services, and the existing number 2 road will become a bay, likely to become Platform 1, generally for WLL services, but the crossovers on the approaches will allow either service to use either platform if required. Windsor Line traffic to/from the WLL can presumably use any of the through roads 2-6.
Bob @ 1108.
ReplyDeleteAdding more peak District Line trains to/from Wimbledon is exactly what is proposed in December this year, following the withdrawal of the Olympia shuttles.
This would suggest the conflicts at Earls court aren't actually between trains from Wimbledon and Richmond.
OTOH interworking between WLL and District at West Brompton is physically impossible without major reconstruction, and at East Putney it requires conflicting flat crossing moves, neither solution being realistic IMHO.
One of the "Anonymous" @ 10.34 / 6th August - is a lying troll, trying to wind me up.
ReplyDeleteI'm getting sick of this ......
As already been pointed out there a number of problems extending LO trains beyond Clapham.
ReplyDeleteWLL would give limited benefit, as East Putney & West Brompton are already connected by the District Line, however the SLL would open up new destinations. If this were a serious project, it may be possible the build a flyover across the Windsor lines. On leaving CJ (platform 2) the Kensington sidings could be used for the ramp, and after crossing the 4 tracks, there is a disused single track siding that runs all the way to Wandsworth town. The a short hop along the slow lines to point pleasant, and terminate at plat, 3 at E.P. On the return the reinstatement of the bridge at Point Pleasant, and onto the slow line.
This would not conflict with either SWT Windsor lines, nor the District Line. It would also give more flexibility for ECS moves via Point Pleasant.
Greg, to be fair to "anon" who you seek to portray as a troll, I would come to pretty much the same conclusion as them regarding your likely reaction. All you seem to do is gripe, which is a shame because you occasionally produce pearls of wisdom too. Ease off the negativity and you can expect people's reactions to you online to do much the same.
ReplyDeleteSo true. I have even got to the point of automatically dismissing what he says but then I sometimes realise there is some sense in the point he made. I challenged one comment once and then after further thought and investigation concluded that he was right and I was wrong, I wasn't going to admit it at the time though!
ReplyDeleteHad my article on the West Anglia draft RUS got published (unfortunately I finished the morning that the final version came out which made the article as it stood rather pointless) I would have given credit in it to Greg for a useful relevant piece of information I did not previously know.
@ Chris M:
ReplyDeleteThanks for correcting my diagram!
@ stevenc:
I don't think there is any source that can help you estimate the cost of civil engineering projects. Tunnelling in north London for 1 mile is cheaper than tunnelling in New York due to different ground conditions.
Building a new bridge in rural Buckinghamshire for example is cheaper than building the same bridge in Inner London, because of the lack of space - more workers are needed and the Inner London bridge would need a lot more planning to make sure it doesn't knock down any surrounding buildings.
Also, costs change. It varies every year. Like petrol - it never really has cost the same for two years for as long as I can remember!
My gripes are usually directed (in this blog) at one source:
ReplyDeleteThe incompetent, nannying, hectoring loud-mouthed bullying so-called "management" of LUL.
I've been using the tube since at least 1951 (Festival of Britain - and yes I can, just, remember using a tram![see *NOTE*]) and the treatment of the, excuse me, PAYING CUSTOMERS, has got a lot worse in the past 10 years.
Also, I repeat, I'm scared.
I really think that, one of these days, the constant, repetitive "announcements" are going to back-fire, fatally, when something serious happens, and no-one takes any notice.
The sort of incompetence that quite casually sent passengers into a death-inferno at King's Cross .....
Compare and oontrast the announcement-level on the Paris Metro. When they make an announcement, it is usually something important:
"the next station is closed"; "we know there are pickpocket gangs here - we've called les Flics", etc ....

ReplyDeleteYes there are problems with leval crosings on the Windsor lines, but they are further west, after Barnes Station, so wouldn't affect CJ - Point pleasant.

RE Extending beyond Clapham Jct in the East Putney direction.
ReplyDeleteAs the Kensington Sidings start at a level with the Windsor lines,which rapidly rise beyond Clapham Jct perhaps a flyUNDER for the Westbound track would be less intrusive?
Just a thought.
Slugabed has omitted to notice Plough Road (UB) BUT it has 6 tracks, and a 6 Track formation extends for practical purposes to Wandsworth Town. So we start by bringing 2 LOROL tracks along the North side of the formation and slewing the 4 Windsor Lines to the 4 South spans.
ReplyDeleteThis then leaves a decision on the future for Wandsworth Town fast line platforms. There is space to rise up with LOROL lines and fly-over the Up lines to pass over the island Platform on a viaduct which will then require a series of piers in the 8 foot between Wandsworth Town and a point at which both tracks then move over to use the alignment of the existing down side single line connection, widening the existing arch piers to support a 2-track bridge deck, and if required keeping the connection from the Windsor Down Slow (a ladder junction East of Wandsworth Town could connect LOROL Up via LOROL Down to Windsor Up Slow for stock transfer connections.
LOROL could terminate at E Putney as I observe that even in mornings Down services seem to be rammed until miraculously everyone piles out at Putney (so this might well diffuse the mass of passengers who would otherwise clog up the Windsors) An E Putney terminus for LOROL might also mean that the single line is all that would be needed (and widening could be deferred).
Wandsworth Town could have platforms on the upper lines (LOROL) which would run over the top of the island platform and connecting down on to the Slow line platforms at the sides. The LOROL side platforms would extend over fast & slow lines below, if it was decided to provide a station for LOROL at Wandsworth Town
From the east, the alignment had 6 tracks up to the station platforms over Old York Road, and then from the River Wandle through to Point Pleasant Jn, where the lines to East Putney diverged.
ReplyDeleteThe alignment bottleneck is the 4-tracks through Wandsworth Town station and the viaduct west over the Wandle.
The options revolve around whether it is worthwhile 6-tracking through this bottleneck AND/OR whether it's worth grade-separating the ELL.
Things are complicated because the Windsor Lines are effectively DF-DS-UF-US, so how would you arrange the platforms with the ELL?
If you grade-separated the Down ELL west of Clapham Jn, then it would join the Windsor Fast Down. This is not a good option, given the capacity constraints on the Windsor Fast lines. So you'd need to create a new ELL Dn through Wandsworth and widen the viaduct to Point Pleasant Jn, i.e. 5-tracking.
If you did decide to invest in 6-tracking then you have to decide where you want to put the ELL tracks:
* 2-tracks on the north side?
* 2-tracks on the south side?
* separate Up and Dn tracks on either side?
Whatever, this is major investment and there's no way you could present a business case for an ELL extension just to East Putney.
I see the solution in either a major investment in the Windsor Fast Lines, or a Northern Line extension.
A new tunneled Windsor Fast line would improve capacity and avoid some of the level crossings. The issues through Wandsworth would then disappear, although you'd still need to grade-separate the ELL Down.
And if the Northern extension to Battersea went to Clapham Jn, it could extend further to rise at Point Pleasant Jn and take the route to East Putney.
Clapham Jn Platforms 1 and 2 should be geared up for up to 6 tph metro services on the SLL and WLL, with reversing lines in the Kensington Sidings.
Was at CLJ on the Windsor lines today (because of the cycle Race I took the train instead of the usual car for this trip) and noticed that multiple contractors have started to mobilise on site around the platforms 1-3 area in the last week or so since I looked.
ReplyDeleteI don't think there is step-free access to *all* platforms like you say. I believe that platform 17, used by Southern's services between the charming Milton Keynes and the divine Croydon lacks a lift. This platform is also sometimes used for Overground trains coming from the WLL is for any reason platform 2 is unavailable.
ReplyDeleteThere may be an easier way to grade-separate the junction from the Down ELL, and that is to have it rise up east of Clapham Jn around the carriage lines. The ELL/WLL passes under the mainlines here. Tricky engineering but may be a neater option.
ReplyDeletePlatform 2: Planning permission has been given to build out the west end of platform 2 to make use of the track between platforms 2 and 3, as has been discussed. This is however a temporary solution and the planned 378 extension to 5 carriages (6 in the control period 5 document) will not allow this arrangement to continue.
ReplyDeleteELL to East Putney: this is technically possible but a flyover/under WEST of the station would be needed at huge cost (east of the station would impact train paths).
Lifts: all platforms inc 17 now have step-free access from the new Brighton Yard/overbridge but not from the tunnel, though the extreme platform gaps on some platforms makes the lifts redundant for disabled passengers.
Platform 1 & 2 staircase: the second staircase from platforms 1 and 2 to the tunnel is being brought back into use to ease overcrowing. Work has been taking place for months but don't know when this is planned to open or how it will function, as the Grant Road gateline will need reconfiguring. Any info?
When I was checking out Clapham Junction to get some information for Franklin for his Carto-Metro map, I contacted NR re information about the proposed changes. They were helpful, and this was part of their response:
ReplyDelete"Platform 2 will be modified, but not as part of the Latchmere Curve work. It will be done as part of the East London line extension, with work due to start late 2011 through to mid 2012.
I can confirm that the back half of the platform will be widened and converted into a bay platform, as well as extended back by approximately 54 metres. The middle road will be used to terminate the ELL trains. This new platform will be known as platform
2. The front end of the platform, which is not being widened, will continue to be used by the West London Line service and will be renamed platform 1.
The ELL works start late this year. The project is at a much earlier stage than the NLRIP Latchmere redoubling project, which is in construction."
In the latest version of his map (v2.1 - http://carto.metro.free.fr/ - Franklin shows the future platfom extension as a broken line. For clarity, he will add the new platform numbers and track layout when they occur.

ReplyDeleteThank you for that informative post - very useful.
The interesting new point above is that the platform 1 and 2 island is also to be extended by 54m. That changes it from the current nominal 10 car length to over 12 car length, so a split into two 6 car sections should be enough for any LO train lengthening for a good few years...
ReplyDeleteRe: platform 1/2 lengthening:-
ReplyDeleteis there any concrete information regarding the lengthening by 56m? To the east, part of the platform is unused but is a) thin, b) has electrical and signalling equipment SWT will not move and c) has no cover. Wandsworth Council made clear they are not particularly happy with the current plans as they will, frankly, look shoddy and my understanding is they are only to do the minimum to allow 2 x 4 car trains. Extending to the west is possible but will require possibly extensive work, which has not been mentioned or referred to in any public documents, unless someone can shed any extra light? SWT and DfT have a long history of not spending a penny on Clapham Junction and the former of being obstructive...
SWT have absolutely nothing to do with infrastructure changes of thsi nature. You mean Network Rail.
ReplyDeleteOn my recent visit to England, I caught an episode of Trainspotters (on Discovery Turbo), which had a great segment on Clapham Junction. I didn't realized it was one of the busiest stations in England, by number of trains stopping IIRC. Not technically detailed by the standards of this blog, but certainly was great to see clips of the station in action. Especially as I'd never visited the station, nor likely to.
ReplyDeleteTrainspotters has several segments per show, some of heritage railways around GB, and some on recent or proposed developments. I believe there was a bit on HS2, unfortunately babbling by in-laws prevented me from hearing much.
