Yesterday I was travelling on a London Midland advance single between Euston and Crewe. When the train reached Stafford the guard announced that "passengers for Crewe,Liverpool and beyond may change here for a faster forwarding service". My travelling companions were ready to leave the train until I argued that we risked a penalty fare for a)stopping short and/or b)not being on the booked train between Stafford and Crewe. They then said the guard was misleading people. Wonder if people have been caught out by this in the past?
