20137 passes Bishop's Cleeve on 4 June 2023 with the Gloucestershire Warwickshire Railway's 15:35 Broadway to Cheltenham Racecourse service. The green livery with TOPS numbers and 0O00 headcode recreates a 1976-80 scene, although the maroon coaches are from slightly earlier era. 20137's classmate 20141 became the last BR mainline loco to retain green livery (excluding specially repainted 40106), and managed to survive in green until May 1980.
