The first of a batch of twenty-six such vehicles under Diagram 2651, they were intended for the London-Bournemouth, London-Portsmouth and London-Exeter services and were of the low-windowed design. Seating twenty four passengers in four seating bays at one end and the kitchen, pantry, service vestibule and side corridor at the other, a set of double loading doors opened into the vestibule, while the passengers accessed the Restaurant from the gangways at either end.
