These coaches were converted from a Brake Standard Open (BSO), by replacing one passenger seating bay with a counter for serving food, and space for a trolley for light refreshments. The toilet was removed and the space converted to a steward's prep-room and store.
Two batches of coaches were converted, as shown below.
