how do they get away with this?
they have done this so they can consistently make the scheduled arrival time so they don't get fined
but this means, very often, (virtually every sodding journey), you have to get to stations and sit there and wait till the train has caught up to its timetabled time (as it can't leave early) and now they have announced trains can leave up to 1 minute before their scheduled time (which has always happened but they have never done it - now they have started doing so!)
have just checked the new December timetable and another minute has been added on
AARRGHHHHHH
