I saw my first one of these trains (picture) while playing football at Wormwood Scrubs in 1976 or '77. We all stopped playing to point at it: "ooh it's one of those new trains!"- it must have been impressive. Or we must all have been real sad-hats. I think that was also the day I scored my only goal for the work team - off my shin came the 6th goal in our 7-1 victory.
