I mentioned my mis-training on another (non-rail) forum and you'd be amazed – or perhaps you wouldn't – how many people said they'd done similar, including someone from Suffolk who jumped on a 13-coach London-bound train instead of the 2-coach local branch-line train to get the two stops from Ipswich to Woodbridge! "Best" though were the people who'd managed to board the wrong plane.
A pal of mine who lives near Parkway and travelled to work by train once jumped on the only train of the day from
BRI» nonstop to Birmingham, leading to a shrivelled dinner. My favourite, poor chap, was on a train from Birmingham to Bristol on a day when the cock-up fairy had been extra busy at New Street. No signals, no PIDs, staff issuing contradictory advice, the lot. Eventually, I found the train myself, a long way from its booked platform, and checked with the
TM‡. As we eventually pulled out, an elderly gentleman of oriental appearance asked him "What time do we get to Telford?" About midnight, you, I thought.
