What are the rules for walking onto platforms 1+2 at Glasgow Central. These are the Virgin Pendolino platforms and they don't have ticket barriers. I have often wondered if I would be allowed to spot from the end of the platform, but wasn't sure if this would be permitted without a valid ticket. I wouldn't board any trains (which I have seen some people do quickly to avoid the 40p toilet charge, often to be going on an accidental hour long trip to Carlisle!) Thanks for any help in advance!
