The 1100 class railcar or Budd railcar are a type of diesel railcar built by Commonwealth Engineering for the New South Wales Government Railways in 1961. They primarily operated on the South Coast Daylight Express until withdrawn in 1993.
During the 1950s the New South Wales Government Railways ordered rolling stock for the Brisbane Limited, including some stainless steel double deck sleeping carriages. Due to financial constraints only ten conventional sleeping carriages were built. To use the excess materials that had been stockpiled, Commonwealth Engineering constructed five cars, four self-propelled Budd Rail Diesel Cars., and a matching non-powered trailer car. 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. There is a myth that the builders had to take considerable care during the design phase to ensure the structural integrity of the cars due to the large opening required for the roof mounted radiators. In fact the roof structure is continuous beneath the radiator blister the only openings being for electrical conduits and tubing, these openings being too small to affect structural integrity.
Commonwealth Engineering built four power cars and a fifth unit as a trailer car. The four power cars (FPB 1101/1102 and PHB 1141/1142) were each powered by the standard Budd Rail Diesel Car equipment of two 300 hp 6-cylinder Detroit Diesel 6/110 engines coupled to Allison RC3 transmissions. BRB 1181 was the only Budd Rail Diesel Car in the world built as an unpowered trailer. This vehicle was fitted with a 6-cylinder Leyland O.350 diesel to power the air-conditioning, buffet and lighting. This was later replaced with a Leyland O.400 diesel. BRB 1181 was easily distinguished from the other cars by having a smaller roof dome.
