Can remember it well. Me and my mate used to ride about on West Yorkshire Metro day rovers when we were kids. Sometimes we'd 'forget' to get off at Leeds and 'have' to go out of West Yorkshire through to York. We loved standing in the gangway peering in to an intermediate cab to see how fast we were going down Church Fenton bank and on to Colton Junction. Often about 80mph was shown which is only 5mph over the permitted speed, but to us boys, it was great because it was naughty! Of course there were no spy in the cabs (OTMR) back then or speed guns, so the only chance the driver would be caught would be if a Traction Inspector was back cabbing. Great times!Interestingly, on the subject of 150's and speedo's, 150273 52 vehicle is odd, in having the only speedo dial on a 14x/15x with Northern, that goes up to 120mph. All others have 100mph.
