context_page_description: Under the Whyte notation for the classification of steam locomotives by wheel arrangement, 4-6-0 represents the configuration of four leading wheels on two axles in a leading bogie and six powered and coupled driving wheels on three axles with the absence of trailing wheels. In the mid 19th century, this wheel arrangement became the second most popular configuration for new steam locomotives in the United States of America, where this type is commonly referred to as a Ten-wheeler. As a locomotive pulling trains of lightweight all wood passenger cars in the 1890-1920s, it was exceptionally stable at near 100 mph speeds on the New York Central's New York to Chicago Water Level Route and on the Reading Railroad's Camden to Atlantic City, NJ, line. As passenger equipment grew heavier with all steel construction, heavier locomotives replaced the Ten Wheeler.
context_section_description: Between 1879 and 1885, the Natal Government Railways (NGR) placed 37 4-6-0 tank locomotives in service. Of these, 18 were built by Kitson and Company and 19 by Stephenson. On the NGR they were designated Class G. When the SAR was established in 1912, the 15 unmodified survivors were designated Class C. The last one was withdrawn from service in the mid-1980s, after more than 105 years in service.
  In 1880 and 1881, the Cape Government Railways (CGR) placed 18 4th Class tank-and-tender locomotives in mainline service on its Midland System working out of Port Elizabeth and Eastern System working out of East London. Four of these locomotives were still in service when the South African Railways was established in 1912.
  In 1882 and 1883, the CGR placed 68 4th Class 4-6-0 tank-and-tender locomotives in mainline service on all three systems. It was an improved version of the 4th Class locomotives of 1880 with larger coupled wheels, built by two manufacturers. Robert Stephenson and Company built 33 with Stephenson valve gear, while Neilson and Company built 35 with Joy valve gear. Of these locomotives, 26 were still in service when the South African Railways was established in 1912.
  Four tank-and-tender locomotives of the CGR's Experimental 4th Class were supplied by Neilson in 1884, built to the design of J.D. Tilney, Locomotive Superintendent of the Cape Eastern System at the time, to be able to use low-grade local coal. They had Joy valve gear and unusual six-wheeled tenders, with the leading axle mounted in a rigid frame and the other two axles mounted in a bogie. One of the locomotives survived until 1912 and was designated SAR Class 04 as an obsolete locomotive.
  The first twenty of the CGR 5th Class tender locomotives were delivered from Dübs and Company in 1890. In 1891, the CGR placed a second batch of thirty 5th Class tender locomotives in mainline service on all three Cape Systems. They were similar to the previous batch of 1890, but differed in respect of the diameter of their coupled wheels, the length of their smokeboxes and their tractive effort. In 1912, when the South African Railways (SAR) was established, the survivors were considered obsolete and designated Class 05. Nevertheless, some of the Class 05 locomotives survived as shunting engines in SAR service for another four decades. They were the last obsolete locomotives to be still in service when they were 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 4-6-0 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
