20228 & 20137 pass Didbrook on 25 July 2026 with the 2C09 09:30 Toddington to Cheltenham Racecourse service, during the Gloucestershire Warwickshire Railway's Diesel Gala. There's a striking contrast between 20228's immaculate blue livery, and the faded green worn by 20137. Apart from the domino headcode, this could be a scene from the mid 1970s.
