Spot on, and get out at the door closest to it.Im not anal about it (if im running late and the train is leaving i wont try to get to my usual carriage) but generally try to get on the carriage that will stop closest to the stairs/exit at the other end.
Ill usually go a single or double seat or stand (those bays of 4 where you face other people can GAGF)
I prefer the bays of 4.
