My daughter and some friends are taking part in the Bridges walk in London this Sunday. I suggested they buy day returns from Rochester to Battersea Park (where the walk starts). The walk ends near London Bridge. As they could either use SE Trains or Thameslink from there, I put the question about validity of returning directly from London Bridge to Rochester with those tickets. SE Trains said it was OK but Thameslink said they were NOT valid. If the TOCs cannot agree among themselves what chance for the poor passenger. They will probably now buy more expensive 1 Day Travelcards to make sure they are not penalised.
