With all the hype about the extensions, of the now named East London Railway, are we getting an LO network fit for purpose. The rush to finish the work before the 2012 Olympics has caused a number of questions.
Why are we just limiting the north end to what will effectively be a terminus at Highbury & Islington. The stock transfer chord will restrict any future extensions without another remodelling and resignalling. 4tph from the south end could operate through Camden Road and Queens Park to Willesden Jcn.
Why not also provide the east cuvre at Dalston and a through service to Stratford. This would provide a direct service from south London to the Olympic site in 2012 and improved connections to the east, avoiding the change of trains at Canonbury on what should already be a busy service. 4tph could operate from the south end to Stratford.
Why not extend the remaining 4tph to Finsbury Park via Highbury Vale, a station here to serve the Emirates stadium and onward to GN suburban stations. Again improving connections to the north of London and not turning trains at Dalston Junction, a station currently planned to be a Junction in name only.
The above would need a larger fleet of 378's, but would provide TfL's requirement for greatly improved connections across London. With more through trains the service will provide easier journeys. The options of a walk between Dalston Jcn and Dalston Kingsland or changing at Canonbury or Highbury & Islington does not bode well for easy traveling.

The rush to finish the work before the 2012 Olympics has caused a number of questions. Nowt to do with the Olympics. It's been optimised operationally. Because they want it fully segregated. Sending more ELL trains west onto the NLL also ultimately limits the number of Camden-Dalston-Stratford NLL trains. Because it be expensive to construct as you need to provide alternate access to the shopping centre, and again limits Camden-Dalston-Stratford NLL capacity. Because it would require a grade separated junction at Canonbury, which would be insanely expensive if not impossible. Otherwise the crossing moves to get to Canonbury tunnel eat up lots of capacity on the NLL.

Nowt to do with the Olympics. It's been optimised operationally. With optimized operationally I take it you mean do as quickly as possible and if it is finished by 2010 all the better. Also could mean that it is still planned as if it is still the ELL and LUL still think it's their railway. If that is the case then LOR has proved to be a waste of time and any chance of a fully intergrated ELR as part of the national rail network will be lost. If it was to be fully segregated, it would not go any further south than the twin termini at New Cross. The continuation south has at least opened up the ELR in that direction so why not the north end. As for putting more trains onto the NLR, TfL proposes 8tph Camden Road - Stratford with 4tph from Richmond and 4tph from Camden Road/Queens Park. This seems to be a little excessive, if all go to Stratford. If the service divided at Dalston Western Jcn the 8tph would be continued from the Eastern Jcn with services from the ELR heading east. The project to date has spent a fair bit of money so that would not be insurmountable. The only insane bit would be to construct a grade separated junction. Connections between all four lines would make operational sense as it would enable services to be run when engineering operations were undertaken on one pair or the other.

No, I mean it's been optimised to be able to run without excessively disrupting other services. The Canonbury junction is a good example - To get to Finsbury Park ELL trains would need to cross both tracks of the NLL 8 times an hour, reducing the number of NLL trains that could run. It'd be madness, especially as Highbury and Islington is almost as good as Finsbury Park.
If you think running 8 tph from Camden to Stratford is excessive, you've obviously never used this route.

I have to agree with cetacean on all these points here. I think a relatively segregated service is a good idea here, and Highbury and Islington is a pretty good interchange point. Camden would be even better, but an easy transfer to those 8 trains per hour it's not too bad.
Finsbury Park would indeed be expensive and I think the existing connection is only single tracked as well, and it would involve so many at grade crossings. If FCC trains would start running from Finsbury Park to Moorgate all day long that would probably make up for this as well.

Speaking of integration, I had the misfortune to travel from Forest Hill to London Bridge yesterday. Boy are those 455 trains slow. The acceleration is dreadful, and the breaking seems to be worse. For each station, the driver would slow down way ahead and we just crawled in, much worse then EPB days.
How will the performance of the new trains compare with the current ones (presmably they will be sharing tracks). 6tph old low spec trains intermixed with 8tph new high spec trains soulds like a schedulers' disaster to me. Any comments?

Not an expert on the 455s but there could be problems!
I thought the east curve at Dalston was going to have a single track running thru it! I hope it isn't wasted, its a useful link line. I think a 4tph New Cross - Stratford service could be run!

While I understand and agree in principle with lnwrelectric's points about integration and operational flexibility I think others in this thread are right.
It's useful also to remember how long the ELLX project has been developing. There have been a lot of changes to the project over this time and even now only two out of three phases (West Croydon/Crystal Palace & Highbury) of the current project are guaranteed. Imagine how long it would take, if at all, to approve all those other parts you would like to see.
One one point I do agree that extending the ELL through Camden, Primrose Hill and South Hampstead to Queen's Park would be very useful. Is it possible to continue pairs of tracks right the way through from ELL to Queen's Park and Stratford to Gospel Oak (and beyond) without having to combine them anywhere between Dalston and Camden? This way capacity would be unaffected on both lines.
The Camden-Stratford section is definitely deserving of 8tph, as anyone who has used the line will know. That section is so busy could probably even use up tube frequencies.

I think it's physically possible, but you'd have the sacrifice the two long freight loops between Camden and H&I that are part of the current proposal and probably key to making the 8 tph timetable work on the two NLL tracks from H&I to Stratford. There's also a bottleneck west of Camden Road where the alignment narrows to two tracks for short distance before the Queen's Park and Gospel Oak routes split. Four tracking across here would be a challenge.
So I think Highbury is as far as you can realistically get segregated. It might be possible to build a flyover west of there where the alignment is quite open to get trains from the eastbound NLL down onto the eastbound ELL without crossing in front of westbound NLL trains. But the business case and planning permission prospects for such a thing surely aren't good.

I think Camden would be a good terminus for the ELR as the 29 bus corridor would provide links to Central London and Holloway and the immediate area could do with a bit of a boost. There's space for four tracks up to Camden Road, are these being put back in as part of the ELL project and/or an upgrade of the NLL? Guess if they are it's for freight to allow the increased service to Stratford not for the ELLE.

Post by DrOne on Jun 13, 2008 9:44:07 GMT
I see Cetacean's point about the difficulty of getting the ELL to and through Camden. However, the use of the freight loops might be reconsidered as the passenger service grows and improvements can be made to the GOBLIN for freight transport. It would then be relatively easy to alter the track work and extend the ELL to Camden with four tracks already in place. Maybe.
Even though I really think Camden would be the best terminating point it's probably best for the time being to be content with the opening of the line and allow passenger demand to determine the way the line evolves.

Just want to add that this week Construction News reports that DfT are funding four tracking of the NLL from Gospel Oak to Stratford, costing £100m. Work includes platform extensions, loops and resignalling. It also costed work on the Dalston Curve at £6.5m with and I quote "reversing platforms at Camden Road" thought the graphic shows the curve work going as far as Caledonian Road & Barnsbury. Full story - mackenzieblu.blogspot.com/ I also thought that the alinement east from Dalston Junction towards Stratford was safeguarded for the future?

The CN article is here. It looks like sloppy reporting to me rather than anything new - the diagram I linked to above is likely to be what they actually build. They certainly ain't four-tracking Camden Road-Gospel Oak. The Dalston Junction east curve is safeguarded and there's a single track gap included in the foundations of the new station/flats. Further north, there are no buildings on it but the Kingsland shopping centre car park's access road runs right across the alignment. Not sure what's happening with the Croydon terminus, though the South London RUS had West Croydon, as planned.

There might be some confusion over the fact that turnbacks are planned both at Camden Rd and at Highbury & Islington, leading people to think the ELL will go on to Camden. As per cetacean's link, the turnback at Camden Rd is for Stratford service and the one at H&I is for reversing the ELL. Seems this is the best operational arrangement for turning that number of trains from two different services.
As for the southern end, I'm surprised that the Croydons are again up for discusion. My feeling is the area might be seen as of too much strategic importance for the route to be changed. However, Croydon does already have SO many good connections to London that it might not be terribly missed. I remember reading elsewhere that it is a difficult section of railway to terminate any extra trains.
My new idea would be to extend the 4tph+ Crystal Palace service to Tulse Hill, Peckham Rye and back up the ELL and to change the the 4tph+ Croydon service to run from the ELL to Peckham Rye, Tulse Hill, Crystal Palace and back up through the ELL the other way round. This relies on ELL phase 2 to connect Peckham to New Cross Gate but it would be an easy way to bring the ELL to more key stations in south London. The other routes would be NXG - Dalston and Clapham Junction - Dalston 4tph each as planned.

Is there no space for the ELR up line to continue at Highbury and Islington? I can see why the line can't be extended if that is the layout since to reverse at Camden the NLL would have to be crossed cutting capacity. That's a real bitch to fix without massive route changes. Thanks for the link.

In my opinion there should be no turning back at Camden. They should run via (a reopened) Primrose Hill to Willesden LL and turn back there. They could even reinstate the second line in the bay.

In my opinion there should be no turning back at Camden. They should run via (a reopened) Primrose Hill to Willesden LL and turn back there. They could even reinstate the second line in the bay. Sadly this is the way public transport is developed in this country. We had a basic 1-vehicle (2-car) DLR because it had to come in at £77m. We then endured years to closures so that it could actually be extended to logical interchange stations and have train lengths extended (and it's still going on). Ditto the Channel Tunnel. A decade or more of Eurostars meandering through Kent before they decided to finish the job and build High Speed 1 (and I can't see a "2" in most of our lifetimes). So with the ELLX project. Of course the trains should run on from H&I to Finsbury Park or Willesden Junction rather than just dump WB passengers there to wait for a probably already crowded NLL service. And they should be planning for longer trains on the NLL too plus the eventual upgrade of District Line services to S8 formation as discussed elsewhere. However as usual the short-term, initially cheaper option is taken; which only ends up costing more then in the long-term when the whole by then existing operation has to be unpicked to facilitate the inevitable upgrade. However it seems that it's this 2-step approach or nothing at all so be grateful, apparently!

It's not going to go to Finsbury Park I'm quite sure. But how much investment would be needed for a completely separated East London line extension onwards from Dalston to Highbury and Islington, Camden Road and on to Queen's Park. I wouldn't get involved with going northwards from there and get conflicting movements with the DLR if it can be avoided.

Are there conflict free reversing facilities at Queen's Park for the DC line? If not WJ might be better. There aren't any major problems with this section currently and Richmond-Gunnersbury seems to run ok too. Re: the investment required for a further separate extension beyond Highbury. Should be like the DLR, where useful infrastructure alterations seem to happen all over the place almost overnight. Like someone said earlier, this may all happen eventually anyway so maybe it's just a case of initially being content with the line opening. Step by step?

As time goes on we'll undoubtedly see the Overground system expand, but does anyone think that in the long long term, the tube system will contract and transfer surface lines to the Overground aswell? We've already seen the East London line go; and if they ever reinstate the line through Highgate High Level, part of the top of the northern will be lopped off...

Queens Park would need a total rebuild. You'll also need to add platform faces on the NLL along the four track section (and sacrifice freight loops). You'll also need to quadruple the Camden section, which would be costly.
Lets look at the amount of people who'd use it: stations north of Dalston - can just use NLL for Camden (and Queens Park when the Stratford-Willesden Junction services come into play) Dalston Junction can use Dalston Kingsland to get to Camden South London (the shared bits) - quicker via NR and tube to get to areas served by such an extension. Several stations (Whitechapel, Shadwell, Canada Water) would be quicker to go via the DLR/tube to at least some of Camden, Chalk Farm, South Hampstead, Kensal and Queens Park Several other stations are close enough to tube stations (Shoreditch High Street, Rotherhithe, Surrey Quays) as to make it likely that there's no point in taking the ELR This leaves Wapping, Hoxton and Haggerston to the whole of the extension, plus a couple of others to a couple of those on the extension you propose.
It's just not worth it, especially when you consider that there would be a fairly easy (guessing step free) interchange at Canonbury and Highbury & Islington to these locations, on a 4tph service.
You have also have the problem of frieght going across the Primrose Hill link, creating extra conflicts. Basically the ELR will be a spur of the Southern network and to have it meet up with something else will cause the possiblity of problems (see Crossrail being a spur of the GWML for another example).

The DLR runs through reasonably unpopulated areas where it's easy to do big infrastructure projects, plus it has very few exists services to disrupt. The NLL is in narrow cuttings and viaducts through conservative dense residential districts and carries all sorts of existing traffic.
It'd be fairly straightforward to continue the ELL to Queen's Park in a non-conflicting manner. The big bits of new infrastructure on top of what's planned are fourth platforms at Caledonian Road and Camden Road (for the NLL on the north side) and four tracking the viaduct west of Camden Road so the NLL had a dedicated route around the corner to Gospel Oak. I presume the Watford DC-Euston service would be ditched under this plan.
The drawback is that you've downgraded the NLL to two tracks along its full length. You no longer have freight loops anywhere, yet freight stays on the line longer as the Primrose Hill route to the WCML is no longer available. You also don't have a turnback platform at Camden Road for the Stratford-Camden Road shuttle. I think you'd be lucky to run 4 tph Richmond-Stratford on this infrastructure.
So the current plan is a trade off between the NLL, ELL, freight and expense. I think what they're doing is a reasonable balance.

The old lines behind the eastbound road at Camden Road, have sinc ebeen hoarded off with wood panels attached to the fence... Peering over the fence, by standing on the catenary support concrete, shows that a lot of dumped rubbish, has been removed. It would benefit the pax service if the freight could be confined to those reopened lines, as at Cally Road & Barns? A conflicting move would only be apparent at Camden Road West Junction, where the Kentish Town and Primmy Hill lines converge/join/separate...

I have heard on the grapevine that there are big plans for the bay at Willesden.. Would take a bit of work as the new station footbridge and the lift are both built on the formation of the missing line. With the shop that uses the old Willesden Mainline PWSS office being built over both formations.

They are only close to the buffers. Would not affect a 3 or four car unit from using a reinstated line. The photo below is about two years old, but nothing has changed.

If you were putting back the other line, as it is new work it would have to meet current standards. Which would mean a sliding buffer, and taking consideration of what was behind the buffer. Which would probably put the buffer face of the new platform about 60' this side of the stairs, which uses a good quarter of the available platform length.
