I have a couple of questions about the VLU concerning capacity.
1) The new signalling has been specified with station run out run in times having to be below a set amount of time? Does anyone know what this time is? (I have observed occasional run out run in times on the Victoria Line of 60secs, and consistant run out run in times on the Central Line of 57-58secs despite its more advanced signalling!)
2) The line capacity will be increased from 28-30tph to 33tph. To get this number of trains through Brixton's crossover, is it likely that the stopping point on approach to the crossover will be moved closer to the crossover? (I think its approx 100m away at present). Or will the improved train performance and/or faster interlocking speeds and switch throw times be used to increase the capacity?
