D8098 & D8137 pass Southam on 28 July 2017 with the 2C53 09:30 Toddington to Cheltenham Racecourse service, during the Gloucestershire Warwickshire Railway's Diesel Gala. D8098 was visiting from the Great Central Railway. The two Class 20s display livery variations from either end of the BR green period. D8098 shows the locos as delivered in the early 1960s, with no yellow panels at all, while D8137 shows the final version, with full yellow ends, from the late 1960s / early 1970s.
