There was some strange ones at Nuneaton in the early 90s. Not a stopping point (more of a timing point, maybe), but on Birmingham to Cambridge services Croft used to appear; on Birmingham-bound services you'd see Coleshill (way before Parkway station opened), and the Coventry line had "Oil Term Jtn" sometimes. This was when the CRT screens had started to become colour at the station. Plus the PA system used to play out the Talking Clock ("At the third stroke, the time sponsored by Accuritst, will be... pip, pip, pip") at 9pm each night - just before the Holyhead InterCity train.
