HST power car availability was not always adequate in the 1980s, and the specially constructed generator van was often pressed into service to allow a locomotive to haul a set of Mk3 HST coaches. Such was the case on 11 June 1984, when 47277 was pictured passing underneath the brick bridge at Compton Beauchamp with what is presumably the late running 1B35 18:28 Paddington to Bristol Temple Meads service. ADB975325, the generator van, is coupled directly behind the locomotive.
