50018 Resolution passes West Drayton on 6 November 1986 with the 1F25 09:20 Didcot to Paddington Network SouthEast service. Unfortunately the framing on this is a little out, with the track on the left slightly cropped. This was taken on a Pentax 6x7 mounted on a homemade bracket, acting as a slave to a Canon A1, through whose viewfinder I looked. Later I re-engineering the bracket with locating pegs that positioned the cameras more accurately, as I was getting too many of these pictures, where the Pentax had moved just slightly out of alignment.
