Am about to book a return ticket from Taunton to London Paddington on 8th Dec. Online FGW and other sites show Super Off Peak Day Travelcard available on the early fast trains to London 0719 etc. How can this be? Is this an error. I'll book it, but would prefer not to have an argument about validity. I thought these were restricted tickets, and not available at this time. Note no advance fares seem to be available either. Any advice gratefully received.
