Your post which I replied to seemed to be saying that the "peakiness" of demand made the overall cost of operating the railway higher (apologies if I've misinterpreted) . If this is the case, then spreading demand will reduce overall cost - if the savings are passed on then this would help everyone, even those who can't change their travel patterns.
It does but trying to force (okay encourage but the effect is the same ) peole to change their travelling habits wont work, everyone will assume it is up to everyone else to change their habits and not them.
We have had enough coverage of the Woking to Waterloo which is 150% loaded (or whatever it was) and the fact that a train 10 minutes later is quite reasonably loaded, how many commuters on that crush loaded train changed their travelling habits and caught the later train? Zero, none, nadda, so I dont think anything will work because people want to travel at that time and that is it.
