No formation details found.
A two-car Class 108 DMU in June 1970 at Grange-over-Sands on the Cumbrian Coast line (the station is hidden behind the train). It has a set number in the left cab window which seems to be AC345 (and so an Accrington set) and the vehicle number seems to be M56256. Mel Smith.
Do you have any images of the set you can add?
