Following the failure of the previous evening's 1A40 21:45 Penzance to Paddington GWR sleeper with loss of air, the empty stock had to be worked to London on 12 July 2018 in order to work that evening's down train. As the Berks & Hants line was closed for engineering works, the train was diverted via Swindon. 57605 Totnes Castle is pictured passing Grove with the 5C99 10:01 Laira to Reading Traincare Depot ECS. Unfortunately the dark green livery does not photograph well in the midday summer sun, but this unusual working just had to be recorded!
