Labelling the coaches, something that they can't be bothered with on 170s any more, why would Scotland's best ever railway need anything as boring as that, is the most important thing to help passengers find their reserved seats.
Info systems telling a platform which way round the train is would be a helpful extra step. If Transpennine can manage it then so can Scotrail.
Drifting off topic, but does anyone know why they can't be a**ed to label 170 coaches A-B-C, it pretty much died with First leaving the franchise? It's not like there's any doubt about which coach is A as far as the train layout is concerned. They could claim that it's to stop confusion when they run as six cars, but obviously that excuse is no good at the moment since they'll never have enough trains to ever run in multiple!
Just label the coaches.
