I can remember a few* years ago I was travveling from Manchester back to Stirling, taking Virgin WC between Warrington and Glasgow. Anyway, I had a booked seat in coach C, but there was some pillock smoking in there (coach B was the smoking carriage). Couldn't be bothered getting into an arguement about it- he was the only other person in the carriage, and I was a seventeen year old schoolboy. I think he might have looked a bit lairy, and I was a wimp.
So, I shifted myself a couple of carriages away. The intervening one was pretty empty, and then there was one with maybe about twenty other people in it. This was party central. A group of Welsh lads were on their way to see the rugby (Six Nations)- though they were planning on watching in a Glasgow pub, rather than going to Murrayfield. They had wine that they were merrily sharing with all and sundry (even the guard got offered some I think), and had a pair of tinny travel speakers hooked up to a minidisc player blasting out Catatonia, Tom Jones, Manic Street Preachers, Stereophonics, Super Furry Animals etc..
Guard passed through a few times- I think he figured that with the train so quiet elsewhere there was no real point in getting all jobsworth on them.
(how much of that seems so dated? WC loco hauled, smoking carriages, mini disc players)
*um, come to think of it, it was nine years ago. Yikes
