I would assume passengers would have been offered that option; they would be entitled to it in my opinion.Would be very interesting to hear from anyone who was actually caught up in this, as to how it eventually worked out, what vehicle turned up and when, what stops were made, and the eventual arrival time in London. Any lurkers out there care to join the forum and let us know?
Personally I think I would have tried to find a hotel in York rather than have such an unpleasant journey.
