The best sighting was 08113 passing Par with 11 vans and a brake forming the return trip from Wenford Bridge to St. Blazey.
As I was modelling the area, I took notes
The sleeper consisted of Mk1 stock including sleepers and a lot of sailors heading for Plymouth
In answer to the question, overnight to Fort William .... the best journey I've ever had as far as scenery is concerned
