Interesting that one about first class, took a train from Clacton to London last year, guard puts me and family in first class which incidentally are the exact same seats as TPE's standard class so for someone out of the area I couldn't tell what the difference was either!
Well ours has white headrest covers, lots of first class signs, some have power sockets, some even have a sliding door. Not worth the £47 he paid, but thats his money, so not my call. If you stay seated there, that's what you pay (and he did nave no ticket at all, so not even an upgrade).
