How is the Guard to know where you are alighting? (Or, in many cases, where you entrained?)
They can ask for the information, and then they can write the date of travel*, the train's headcode, and the words "Up to", followed by the three-letter code of the station you have told them you're travelling to.
If the passenger doesn't know exactly when they'll alight, some misuse can still be prevented by marking the ticket with the name of the next stop.
It's very possible to overthink this one!
