Igelkotten said:I'm not so sure about that, actually. Now, I am no expert on LU rolling stock allocation and maintenance procedures, but the various fleets must be allocated to a few home depots on their respective lines, mustn't they? After all, it makes no real sense to drive a train across the whole of London just to get it to a maintenance point or suitable starting location for the service pattern. Thus, units on one line would tend to be stuck on that line for practical reasons, except in exceptional circumstances.
I can see what you are saying, and for todays railway this is more or less the way it works. However, most lines do not operate in the way the sub-surface lines can.
Providing the current layout/depots are still much the same when the stock arrives, there will be numerous depots and sidings fully accessible to the whole fleet.
I doubt train operators route knowledge will be extended to cover the entire SSL, so you won't have stock "in a different place" due to some Upminster-Amersham service.
However, average service disruption could see any stock used to cover a service interval. There are many times when we have the staff but no available stock.
Currently, a gap on the Circle Line cannot be filled by a Met train on it's way to Aldgate. But let's say in the future they have made the sensible move of putting drivers back at Baker Street. The Met arrives at Baker Street, gets picked-up by the Circle driver. The passengers already heading to Aldgate complete their journey as planned, and the gap on the Circle is filled.
That's a basic example, and of course stock is then required to be found for the Met train's northbound trip, but it shows how generic stock could help.
If we then have to take in an extra part of the equation - that the stock cannot be used as the seats are the wrong way around - then we are back to square one.
The tube is meant to be "turn up and go" and in years to come, many more people may use us. We need carriage space, albeit standing room, to get these people around. The average journey is only a few stops. With better reliability this journey won't take as long, so you won't be standing as long.
