Out in the coaching-stock yard of Swindon Works, around the
back, stands the famous Track Testing Car based on an original Dean carriage and colloquially known as the ‘Whitewash Coach’. Marshalled in a test train, any track irregularities causing the vehicle to sway too much caused a load of whitewash to be dumped on the track, so telling the men on the ground where to look for trackwork problems. Nearer the camera is a Collett BG full brake, but it is interesting to note that the Mark 2 FK in the background is mounted on Mark 1 bogies.
