we booked an advance 1st class ticket with seats ticket travelling from Edinburgh to Stansted[Virgin section to KingsX] on 8 July 16 @0730.The train left Edinburgh on time but stopped at Berwick because of power line chaos.We were told the train was cancelled and would return to Edinburgh were all restrictions were lifted and we could use VirginWestCoast to get to London but no seat guarantee.First available West Coast was at 10.50 which was overcrowded because of the east coast cancellations and we ended up in a 2nd class vestibule until London and eventually [using the other connecting sevices] arrived at Stansted almost 5 hours later than we should have.NOW my question is .. the ticket was one ticket right through to Stansted but booked through the TrainLine [not Virgin's site] .. do we claim on the delay pay part of Virgins site and can we claim the cost of the entire journey and not just the Virgin sector..Thanks in advance for any answers.
