It’s interesting that trains came up so quickly in the thread - only a few weeks ago I stumbled upon a Trainee driver taking over the Scotrail twitter for the day, it made interesting reading, and I made a mental note to find out more in case the proverbial diverted fanwards.
Thanks to realECMLdriver and all who have replied - whether about trains or otherwise. I wonder if there are others out there with stories they would care to share... thanks in advance.
