I mentioned this in one of my first posts on this forum, but, given the latest 'news' I'll repeat it here. Long time ago, but that's irrelevant. Early 1970s, I was management trainee with London Transport and had a stint with the Underground side: first posting at Earl's Court with Piccadilly and District lines, out with District Inspector at Hammersmith, and an eastbound Picc came in, stopped correctly, doors opened. Then the train started moving backwards, doors still open. We were on the District platform, but right opposite the driver's cab, and saw the driver apparently asleep. I'd estimate the train moved back about 20 feet before the D.I. went over (I wouldn't say rushed) and knocked on the cab window, which seemed to wake the driver from his slumbers but imo just as a drunk would rouse i.e. he still seemed half gone. The D.I., who was probably one of the most laid-back individuals I've ever come across, mouthed from the other side of the window to ask if the driver was OK, he nodded, and the train went off again as though nothing had happened, no report, no comeback. I've got to say I was shocked by the whole thing, but the D.I.'s word was gospel and who was I to argue? He was about to retire, he wanted an easy time, but the fact I can still recall the details 45 years later shows I still feel shame that I didn't kick up more of a fuss - the very minimum I think he should have done was to go into the cab to establish whether the driver was drunk, ill or just fatigued. Nothing happened to the train on its onward journey, of course, but no thanks to us.
