GWR Castle No 5006 Tregenna Castle at West Drayton in 1932.
The experts think it is an Up Torbay Express with an extra Full Third Clerestorey coach leading the main train formed of the usual 1929 stock but with the notable exceptions of the fourth, fifth and sixth vehicles which comprise one of the GWR’s articulated triple dining car sets. These triple diner sets were rebuilt as conventional vehicles from the mid ‘30s.
