That does of course rely on at least one person being awake!
One of my colleagues (who travels on a non
FGW▸ train line), goes to a station which is the first one where the doors open on one side of the train.. All previous stations the platform is on the other side.. So his adopted tactic is to fall asleep standing up against the door.. When he gets to his station, it opens, he falls out! He still manages to miss his stop regularly though when he is too tired to stand up...
