Just two wagons loaded with concrete sleepers is not much of a load for 66550, pictured here passing South Marston on 7 December 2022 with the 4E18 09:47 Fairwater Yard to Doncaster Wood Yard, which although often a short train, is usually a bit longer than this! This had left 37 minutes early, and had managed to add another 100 minutes to the early running by this point.
