Yes, London Waterloo to Reading to Taunton is a permitted route on a London Terminals to Taunton ticket.With an FGW super off-peak return from London Terminals to Taunton, can I change at Reading on the return leg and travel to Waterloo rather than Paddington? I'm looking to break that leg of the journey at Wokingham for a few hours.
Who you buy a ticket from makes no difference to its validity. It's the same ticket whether you get it from FGW, SWT, Northern or Raileasy. (The only difference is whether they decide to levy a booking fee...)It was any permitted. Sorry, I was a bit unclear in my first post. Meant 'bought from FGW' rather than 'route FGW'.
