Description
These coaches were the first of the Stanier period gangwayed designs, having shallow single element sliding window vents and retaining torpedo type roof vents. The tank filler pipes at the passenger end were also, unusually, cranked inwards against the sides of the gangways. As general service coaches they were seen throughout the LMS and BR(LMR). Two coaches were quickly modified with luxury two per side seating in the first class compartments and given the diagram number D1939.
