One Summer Saturday in 1986 I'd spent the day doing moves based on York. I'd had a filthy non-boiler 37 to Darlington and a 47/3 back, then a 31/1 out to Scarborough and a 45/0 back. So far so good. Large crowds were about for the Races and instead of the booked DMU on the teatime Sheffield via Pontefract working a pair of 20s came whistling off the shed and hooked up to some mk Is. Bashers everywhere and the DMU back from Church Fenton was wedged. Back into York to see the very surprising sight of 50047 burbling away on a relief to Plymouth. Rode with this to Sheffield before returning behind a nondescript 45/1.
