Super power for a very short train. 47238 Bescot Yard & 47312 pass Cholsey on 16 August 1991 with just a single five vehicle freightliner flat set, loaded with 14 boxes (13 20ft containers, with a single 40ft box on the rear). As the only booked freightliner trains in the working timetable around this time had already passed, this is a mystery working.
