Can I get a refund if my train was cancelled?
If your train is cancelled you can return the unused ticket at that time to any ticket office and claim a full refund. This applies to all types of paper ticket, regardless of where they were bought. Alternatively you can send your unused tickets to the train operator and they will give you a full refund.
In the case of electronic tickets (those on smartcards such as Oyster or on mobile telephones or other electronic equipment) you should check how to proceed from where the ticket was bought.
