Passenger workings were rare, but they did turn up on Summer Saturday specials to Ayr nd places like that. Oddest use was on the East Kilbride branch with a rake of 4 BR Std non corridor coaches. I stayed at Coatdyke with my bedroom window looking out on the embankment to the east of the station from when I was 7 until I was 24 so I saw a lot of them on coal and scrap trains going through Coatdyke station, sometimes you could see the plume of black smoke before the train appeared, they were always in pairs! D8500 was treated as a bit of a pet by Polmadie and was used on ECS workings from Larkfield to Central and was always in immaculate condition whenever I saw it, it was one of the ones transferred to the LMR for banking duties on Shap at the end of steam. Last memory was an early Glasgow Works open day when there were plenty of them to see awaiting scrapping.
