In 1911 the Natal Government Railways placed the first two of seven 4-6-2T Pacific narrow gauge tank steam locomotives in service. Five more were delivered to the South African Railways in 1913 and 1914. They were all built by Kerr, Stuart and Company and numbered in the range from NG10 to NG16. 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.
