eventually withdrawn in 1953. The Cape 6th Class passenger locomotive was designed at the Salt River works of the CGR according to the specifications of Michael Stephens, then Chief Locomotive Superintendent of the CGR, and under the supervision of H.M. Beatty, then Locomotive Superintendent of the Cape's Western System. It was to become one of the most useful classes to see service in South Africa. In 1912, when they came into SAR stock, the 6th Class family was reclassified into twelve separate classes. In 1893 and 1894, the CGR placed forty 6th Class locomotives in service, built by Dübs. Ten of them, sold to the Oranje-Vrijstaat Gouwerment-Spoorwegen (OVGS) in 1897, eventually became the Class 6-L1 on the CSAR. In 1912, all forty were assimilated into the SAR and retained their Class 6 designation. (Also see Sudan) In 1896 and 1897, the CGR acquired a second batch of fifty, built by Dübs and Sharp, Stewart and Company. These locomotives differed from the previous order in having slightly larger boilers with an increased heating surface and higher coal capacity tenders. In 1907, one was sold to the Benguela Railway in Angola. The remaining 49 locomotives were designated Class 6A on the SAR in 1912. (Also see Angola - Cape gauge and Sudan) Between 1896 and 1898, the OVGS placed 24 new Cape Class 6 locomotives in service, built by Dübs, Neilson and Sharp, Stewart. During the Second Boer War, these locomotives were taken over by the Imperial Military Railways (IMR) and after the war they became the CSAR Class 6-L2. All but one were assimilated into the SAR in 1912 and were designated Class 6C. (Also see Sudan) In 1897 and 1898, the CGR placed a third batch of 55 in service, built by Dübs, Neilson and Company and Neilson, Reid and Company. They were virtually identical to the previous fifty, except that they had bogie-wheeled tenders. In 1907, four were sold to the Benguela Railway in Angola. The remaining 51 locomotives were designated Class 6B in 1912. (Also see Angola – Cape gauge and Sudan) In 1898, a fourth batch of 33 were placed in service by the CGR, built by Neilson, Reid. These represented a further advance on earlier 6th Class locomotives, with a greater heating surface and a larger grate area. In 1912, they were designated Class 6D on the SAR.
