Last time I went by train was for an F.A. Cup tie there many years ago and we were met on the station platform by the Staffordshire Constabulary handing out Welcome to Stoke leaflets which directed us to a bar at a Students Union place. There were double decker buses then to take us to the ground and back again to the station after the game. Not sure if this will be the case for the League game on Saturday though. Check out Footballgroundguide on the internet for up to date info. Hope this helps.
