Looks like we are both RAIL magazine subscribers ContinentalClub! I have been for a number of years now. Barry Doe is very good in what he finds, although I don’t agree with his view that there should only be single tickets and no returns, it does show he is a little out of touch with customer needs.
I have not travelled up the East Coast since June but certainly then I purchased a cheaper 1st advance ticket from FGW than I could get through NX at the time.
I am not sure now how I started using FGWtickets but it was in the days before the trainline started charging booking fees etc.
