Actually it not my mistake! you don’t think I would admit something like this on here do you?
A few years ago, at a company I worked at. we used to ship from Felixstowe to either Europoort or Zeebrugge and then catch the train from Freiburg in Germany to Milan when tipping Italy
At the terminal in Freiburg it was quite well organised, but could be very busy.
Once you have your tickets and in those days cleared customs you were directed to the lanes for the correct train. This bloke Pete, then parked up waiting for the train which would arrive later in the evening.
You then drove on to the train and placed chocks under your wheels before carting your sleeping bag and pillows down the track to the sleeping compartment. Most drivers also took a few cans and some food with them to eat on the journey.
Pete had walked down the track following some other drivers and claimed a bunk in the carriage 
and went to bed.
It was only the next morning when he woke up to find himself in unfamilier surroundings, He was in Lugano in Switzerland, and his truck was in Milan without a driver
A 50 mile taxi ride, paid out of his own pocket, to cover the mistake up 
and that was the end of the problem,!!!
Except the company got a bill for holding the train up, as they had to split the train in Milan to get the rest of the trucks unloaded until he arrived, very red faced in the Taxi
Because he had got out of the right hand side of his cab and followed some drivers to the sleeping carriage, he forgot that they were on the Lugano Train and he had parked on the correct Milan train, The sleeping carriages were coupled up after the train was fuly loaded, so they had an L or an M on the destination board
