Thank you for your update and no hopping on the GWR. The problem I have forseen, is that I am ok on the TLF trains but exit or entry at reading will be the problem as I will not have a ticket, as the tech does not work with the oyster cards at reading. So can I take your reply as the voice of TLF,or should I take this up at TFL? Which I can then take back to Reading (GWR).
