It doesn't even go to the right places.I don't think there is a real shortage of track capacity on the proposed Crossrail Paddington line, as they run some absurdly short trains (3 cars) even in the peak hours. The Crossrail Shenfield line capacity could be increased by platform lengthening. The real capacity bottlenecks are at Lewisham and Raynes Park. That suggests that a better Crossrail route would run between Lewisham and Raynes Park. Hard to do above ground because of those brick viaducts, and I'm not sure if there is room for more tracks on the surface as you get near Lewisham or Raynes Park. It would probably have to go underground, and ideally it should run via the City and West End. And 4-tracking through Borough Market Junction. Without Thameslink 2000 or something similar, that may not be strictly necessary, but there could be some operational simplification in that the fast and slow tracks could be kept separate. The limiting factor is not so much the viaduct but the platform capacity of Charing Cross and London Bridge stations. Overcrowding on the South Eastern could be alleviated by completing the suburban platform lengthening to 12 cars and actually running 12 car trains. There is no practicable way of lengthening platforms 1-4 at Waterloo. Platform extensions to the south would block the station approach. Platform extensions to the north would encroach on the concourse. However you could reduce the number of platforms and lenghthen the remaining ones. To run more trains you would need better signalling. Double-decker suburban trains are another possibility, but there may not be enough height. |
