nYou have to take my comment in its context, here in that of as reply to deepgreen. There are many practices that haven't hurt anyone - until they do. As for this practice, leaving the driving seat to cross the cab for a token exchange at low speed, I would suggets it fits very neatly inot the 'no one has been seriously hurt......yet'. Token exchange on the move is being looked at on some of the more safety conscious railways, already stopped on NR, as part of the examination of risks that leaning out of trains poses. Peopel have leant out of trains for over a hundred years, but this is now seen as highly dangerous and we are having to act. Simply dismissing this post as talking rubbish is very silly, especially as you consider yourself a SME. Perhaps you'd care to divulge that role?
