In 1880 the Natal Government Railways placed a single 0-6-0 saddle-tank locomotive in service. It was virtually identical to the Natal Harbours Department's locomotive John Milne of 1879 and was built by the same manufacturer. During 1905 or 1906 the locomotive became part of the Natal Government Railways Class K.
In 1880 the Natal Government Railways (NGR) placed an order for a 0-6-0 saddle-tank locomotive with Hunslet Engine Company in Leeds. It was virtually identical to the locomotive John Milne that had been supplied to the Natal Harbours Department from the same manufacturer in 1879 and was built to the same design but with some differences in detail, such as is visible on the sides of their respective smokeboxes. The locomotive was numbered 15 in the NGR number range, following on from the numbers allocated to the NGR’s first batch of Kitson-built 2-6-0T locomotives of 1879.
The NGR’s no. 15 was still in service by 1909. During 1905 or 1906 a locomotive classification system was introduced on the NGR and no. 15 became part of the NGR Class K, which consisted of a potpourri of different tank locomotive types that also included two 0-4-0ST locomotives of 1891 and the remaining four of the 2-6-0T locomotives of 1877.
It is not known whether the locomotive had been scrapped or sold by 1912, but it was no longer in service when the South African Railways (SAR) renumbering and classification was implemented in 1912, since it does not appear in the classification and renumbering lists issued by the SAR Chief Mechanical Engineer in January 1912.
