The CSAR Railmotor of 1907 was a South African steam railmotor locomotive from the pre-Union era in Transvaal Colony. In 1907, the Central South African Railways acquired a single self-contained railmotor for the low-volume railmotor passenger service which had been introduced the previous year. The predecessor vehicle was a railmotor engine which consisted of a single 19 Tonner 0-4-2T locomotive that was modified and semi-permanently coupled to a modified 3rd Class side-door passenger coach. On the new railmotor, the passenger coach was an integral part of the locomotive itself.
