In my case most of the waiting area seats were taken and the queue formed because there was also disruption from the previous train which was cancelled. I was just hoping nobody would get my seat double-booked.An entirely self-inflicted problem. Every time I've been without fail there's an absurdly long queue of people 45 mins or even an hour before departure, while the upstairs seating area at the end remains mostly empty. When they announce boarding you come down the steps and merge into the front of the queue anyway.
But of course, create an airport-like atmosphere and you get airport-like behaviour.
I actually can't see ticket acceptance being a normal practice to be honest. I expect Virgin's shorter train formations will mean it'll be easier to fill them up with regular paying passengers with less room for spare. I don't know if as international open-access operators they have the same obligations as ones on the National Rail network (I'd certainly welcome such knowledge if anyone has any). I for one wonder if Virgin will accept Interrail since some operators like NTV Italo actually don't.so any clue if Virgin or Eurostar will accept the passengers of the other during disruptions?
at the moment its simple to put people on the next Eurostar if delayed (e.g. long security checks) but what happens of the next train is a Virgin train?
