Leaving the puns aside for a mo, there's an account in the NRM of one of Queen Victoria's overnight train trips from Balmoral to London. About 3 separate train crews, a train that went ahead to check the line, all other traffic on each section cancelled, and a slow running stage in the early morning, to allow their majs to have their baths without too much slopping water.
Didn't they have to have a man with a red flag, in front?!
Seriously though, I've read all sorts of stuff about Q-Vic's railway habits. It seems her maj expressly ordered that her train would on no account exceed 40mph. The railway company knew that, at that speed, she'd never make her schedule on time, so they quietly made up the speed during the night in the hope that both Vic and Alb would be sound asleep and wouldn't wake up ....

If they'd found out, what would have happened to the driver?
And there was something about all the points along the route had to be
locked into position with padlocks. Thing was, in those days any young rascal could alter the points just with a pair of wire cutters - and the thought of her maj's train being derailed with a bump, even at 40mph, was too much to countenance...
