Commonwealth Railways CB class railcar

The CB class were three stainless steel Budd Rail Diesel Car RDC-1 railcars that the Commonwealth Railways ordered in October 1950 for service in Australia, where they were the first stainless steel carriages. After trials on the Trans-Australian Railway between Port Augusta and Kalgoorlie they entered service in May 1951 between Port Pirie Junction and Pimba, extended to Woomera and Tarcoola in 1952. All were delivered with twin General Motors diesel engines, and CB3 received Rolls-Royce engines in the mid-1960s. Four second-hand Brill carriages from the Reading Company served as trailers. The cars passed to Australian National in 1975, were refurbished in 1986 for the Iron Triangle Limited and the Silver City Limited, and were withdrawn by December 1990 after CB3 was damaged in a 1988 level crossing accident. CB1 is at the National Railway Museum and CB2 is in storage at Port Augusta.
