I can never understand why passengers continue to force themselves onto what is obviously an overcrowded train and then complain it's unsafe and dangerous. Why not simply wait for the next one?
First Class is and should be for First Class passengers only. You can't start declassifying every peak train because the first carriage that everyone will head for is the First Class one. If you want to sit in First pay the appropriate fare.
Good on the train manager in this instance although I suspect there's more to this story than is being reported. I can't see the passenger politely refusing to leave can you?!
Because they may have advance purchase tickets and therefore be liable to a large "fine" if not on the booked service.
Also perhaps a fear that the next train might be even worse, or not run at all.
I would agree though that first should not be routinely declassified on busy trains, I for one pay the first class fare on trains that I suspect will be busy in order to avoid the overcrowded bit.
If a service is regularly overcrowded, then ideally it should be lengthened or an additional train be provided shortly before or shortly after the busy one. If this can not be done, then at least matters could be slightly relieved by not selling ANY discounted tickets for that service, full fare only.
I have long thought it daft that last minute travel on a near empty train requires payment of the highest fare, and that discounted tickets are available at a LOWER advance fare for very busy services.
