In 1911, shortly before being amalgamated into the South African Railways, the Natal Government Railways placed the first two of seven Pacific narrow gauge tank steam locomotives in service. In 1912, when these two locomotives were assimilated into the South African Railways, they retained their engine numbers but with an "NG" prefix added. Five more of these locomotives were delivered to the South African Railways in 1913 and 1914. When a system of grouping narrow gauge locomotives into classes was eventually introduced somewhere between 1928 and 1930, they were all classified as Class NG4.〔 ==Manufacturers== Like their two predecessors, the Hunslet Side Tank and the Hawthorn Leslie Side Tank 4-6-2T locomotives, the third batch of narrow gauge Pacific tank locomotives of the Natal Government Railways (NGR) were also built to the design of NGR Locomotive Superintendent D.A. Hendrie, but using the Hawthorn Leslie drawings for the Class NG3.〔 Between 1911 and 1913 the High Commissioner for the Union of South Africa placed three orders for altogether seven of these locomotives with Kerr, Stuart and Company. * Two locomotives were ordered on 10 January 1911 and were dispatched from the factory in September of that same year with Kerr, Stuart works numbers 1207 and 1208, for delivery to the Natal Government Railways. They were numbered NGR 10 and 11 and designated Class N.〔Jux, Frank (1991). ''Kerr Stuart & Co. Ld. – Locomotive Works List'' (1st ed.). England: Frank Jux.〕 * Two more were ordered on 28 September 1912 and were dispatched from the factory in April and May 1913 for delivery to the South African Railways (SAR), with works numbers 1294 and 1295. They were numbered SAR NG12 and NG13.〔 * Three more were ordered on 10 June 1913 and dispatched from the factory in July 1914, with works numbers 1342 to 1344. They were numbered SAR NG14 to NG16.〔 This last order also included the final two of the Class NG8 4-6-0 tender locomotives that were delivered with Kerr, Stuart works numbers 1345 and 1346.〔〔(Plant, K.P.
