the standard gauge Commonwealth Railways lines in the sparsely populated north of South Australia not served by the South Australian Railways. They operated between Port Pirie, Woomera, Tarcoola, Marree and Whyalla. In July 1975, when the Commonwealth Railways were succeeded by the Australian National Railways Commission (successively branded as ANR, Australian National and AN), they were withdrawn from service and stored. In 1986, however, they were reinstated on the Iron Triangle Limited service from Adelaide to Whyalla and the Silver City Limited service from Broken Hill. The cars were withdrawn from service in 1990. , CB1 was preserved at the National Railway Museum, Port Adelaide; CB2 and CB3 were privately owned. In 1961, Commonwealth Engineering built five RDC-1 derivative cars in Australia under licence for the New South Wales railways department. Four were self-propelled and one was a trailer car. Allocated as the 1100 class, they followed Budd car layouts but were smaller than standard RDC-1 models, being shorter at and built to a loading gauge smaller than North American. The trailer car was built with a buffet/snack bar in one end. The cars worked the South Coast Daylight Express between Sydney and Bomaderry. Age and mechanical problems led the cars' conversion to locomotive-hauled coaches; beginning in 1982; the last self-propelled run occurred in 1986. Brazil RFFSA (Brazilian Federal Railways) purchased four RDC-1s and two RDC-2s in 1958. These were gauge but otherwise standard configuration. RFFSA ordered 23 more cars in 1962–1963. Four of these were gauge RDC-1s. The other 19 were gauge and varied considerably from the standard RDC-1 design. The car body was based on the Pioneer III coach. Internal seating was 48 with a small buffet area or 56 in an all-coach configuration. Several RDCs remain active on the Serra Verde Express tourist train. Cuba In the 1950s, both major railway companies in Cuba purchased RDCs. Consolidated Railways of Cuba (Ferrocarriles Consolidados de Cuba) ordered 11 RDC-1s and 5 RDC-2s in 1950. These operated either singly or in multiple units of up to three cars. The Western Railways of Cuba (Ferrocarriles Occidentales de Cuba) ordered four RDC-1s and six RDC-3s in 1956–57. The cars remained in use after the Cuban Revolution with the Ferrocarriles de Cuba and operated into the 1980s. At least one Cuban RDC-1 still existed in 2017, stripped of all mechanical components and serving as a passenger coach. Saudi Arabia The Arabian American Oil
