A long time ago, when I was nowt but a lad, I had a friend who was a guard at Leeds who - like me - was a fan of clss 40s. One night he invited me to join him on his diagrammed trip on the 21:50 York - Shrewsbury to Stockport, returning on the 22:50 Shrewsbury - York to Leeds. All went well until the return journey, where we were seated in a comfy first class compartment with the lights off and the heating on. We awoke with a start at Huddersfield, where the station staff were beginning to panic as they couldn't find the guard, and feared he had fallen out somehow. The train was delayed about 5 minutes as a result - not much, but as it was a Post Office train it was closely monitored, and a "Please Explain" soon followed. He concocted some story about the connecting doors between carriages being faulty, and him becoming stuck between carriages. I'm not sure anybody believed him, but he got away with it.
