Does anyone know which platforms on the NLL / WLL lines are UNABLE to take 4 coach trains still ??

South Acton to Homerton
• Complicated sites at
• Dalston Kingsland (inc
SME)
• Kentish Town West
• Willesden Jct HL
• Gospel Oak

Acton central seems big enough to take 4 coaches.

Perhaps signal sighting is taken in to account? And also the level crossing..

Does anyone know which platforms on the NLL / WLL lines are UNABLE to take 4 coach trains still ?? The locations shown on the quail maps as only 3 cars are: North London Line: Willesden Junction High Level (Platform 4 = up / eastbound) Kensal Rise Brondesbury Park Brondesbury West Hampstead Finchley Road and Frognal Hamstead Heath Gospel Oak (Westbound, platform 1) Kentish Town West and Dalston Kingsland All the West London line platforms are fine and already take 4 car Electrostars (except Willesden Junction above). On the DC lines Willesden Junction platform 2 (the bay) is also too short. Of these, Willesden Junction, Gospel Oak and Kentish Town West are probably the worse to 'fix' due to their locations. The rest look like they have sufficient space for platform lengthening, although Dalston Kingsland depends on the works for the ELL which come in behind the station. There may also be problems at other locations, as even a 3 car 378 unit is slightly longer than a 313. |

Willesden Junction High Level is a tough one. I suppose the way to go would be SW, i.e. over the main lines. Straighter and less of a gradient. Would probably cause disruption to the WCML though.

Surely lessons for platform extensions on LO could be learnt from the DLR platform extension project, where the railway has remained operational and roads beneath the extended platforms have stayed open.

As a "Light Railway" some/all of the engineering work on the DLR will theoretically be lighter than for heavy rail structures. This will, equally theoretically, mean that some of what the DLR was able to do will not be possible for London Overground to do and working over an operational railway is probably different to working over an operational road - this does not mean the same principles should not apply though.
In vein of the IANAL ("I am not a lawyer") disclaimers readers of many internet discussion groups will be familiar with, I would like to stress IANAE ("I am not an engineer")!.

The comparison with the DLR is also hard because the signaling system there is much more flexible, with many more crossovers etc.
Remember that many of the routes on the DLR have had periods of closure, for example the work between Crossharbour and Greenwich which lead to complex operations with a change of train at Island Gardens for several weeks last year whilst work was undertaken. There was also the rebuild of Tower Gateway which took a while.
Lengthening of NLL platforms on the line west of Camden Road is also likely to be less disrupting because much of the platform work at the difficult spots is linked in with trackwork to increase capacity.

Hi
I believe work to extend the platforms at Willesden Junction High Level are currently in progress and is linked with the construction of the new subway from the high level to the low level footbridge. (Plus the work being carried out on the low level bays.) Give it a few months and you won't recognise the place! - long overdue IMO.
Regards
Martin

The work on Dalston Kingsland and Homerton will take place when the section of line between Gospel Oak and Stratford is closed in December for a period of 4 months. No doubt work to Kentish Town west could also be done during this period as well. However i think that is one of the dificult stations to do because of its location on a viaduct and buildings and other stuff underneath. I have been told that Dalston will be extended by knocking the bridge down (the one near the signalbox) and rebuilding the bridge to fit the platforms under it.
With regard timing of the 3/4 coach trains. i think a lot of it came down to budgeting by TfL. The 3 cars trains were already agreed before the extentsion to 4 was added.

Will London Midland trains call at Willesden when the platform extensions are complete?

The long answer is that the LO platforms being extended at Willesden are the High Level which LM services never go through and never would do. There are no longer any platforms on the WCML lines, so there's nothing to extend to let LM trains stop there (it'd also make a mess of their nice new timetable adding inner suburb stops).
(LO do (normally) operate a couple of late Saturday night services on the DC on LM's behalf, however they only stop at stations that would receive LM services anyway.)

Sorry I meant Southern, not London Midland. I get confused with Southern using LM trains.. sorry!!

Same answer as for the LM..

The lines used by the Southern services diverge from the Overground WLL services before willesden junction H/L and are parallel to the mainline by that point.
Would be pretty handy sometimes if there were platforms though so southern services could stop.

So there is no way to join the main DC lines going North, after passing through Willesden Jct HL ??

No, to get from the High Level part of Willesden Junction to the Low Level part (or vice-versa) requires reversal east of the station, in the Kensal Green Junction reversing siding. The only 'easy' through route is from Watford Junction - Willesden Junction Low Level - Kensal Rise - Gospel Oak - Stratford (and vice-versa). There have been plans for new platforms on the West Coast Mainline, either on the slow lines (as used by LM services) or on the Willesden Relief lines (as used the Southern services); but none of these plans is currently being progressed. |

If anyone is around Willesden Junction you will notice it is slowly being turned into a building site, a lot ground work has already been started. Half of platform is fenced off, the eastern end of platform 5 has had the wall knocked down and preparedness for the extension across the dc line. Inbetween the highlevel and the city lines excavations have started. |
