During the 1950s, the Department of Railways New South Wales ordered rolling stock for the Brisbane Limited, including some stainless steel double deck sleeping carriages.
While following Budd RDC layouts, these cars were smaller than standard, being only 77 feet in length and narrower in width to fit the NSW loading gauge.
The trailer car had a buffet providing light refreshments located at one end and seating for 50 first class passengers.
The remaining three were pooled with the 1200 Class railcars and worked as locomotive hauled cars to operate South Coast services from November 1983.
