3775 working as station pilot shunting a couple of empty trailers but they are the wrong way round, driving ends facing west, so we’re not quite sure what is going on!

Peter Kerslake adds "The answer is that the stock is probably for the Chalford or Sharpness services which were worked using auto trailers as there were no turning facilities at either location. Horton Road depot in the background supplied both engines and stock for these duties, both of which ended on Saturday 31st October 1964."
