The '''Natal Government Railways Class K 0-6-0ST''' of 1880 was a South African steam locomotive from the pre-[[Union of South Africa|Union]] era in the [[Colony of Natal]].
In 1880, the Natal Government Railways placed a single {{nowrap|0-6-0}} saddle-tank locomotive in service. It was virtually identical to the Harbour Board of Natal's locomotive ''John Milne'' of 1879 and was built by the same manufacturer. During 1905 or 1906, the locomotive was designated {{nowrap|NGR Class K}}.<ref name="Holland 2">{{Holland-Vol 2|pages=126–127}}</ref><ref name="NGR Annual 1904">''The Railway Report for year ending 31 Dec. 1904'', Natal Government Railways, Annexure B, Durban, January 1905.</ref><ref name="Middleton">[[:Talk:NGR Class K of 1879#Information on Natal 0-6-0ST of 1879 from John Middleton|NGR Class K of 1879, John Milne & no. 15]]</ref><ref name="NGR Annual 1906">''The Railway Report for year ending 31 Dec. 1906'', Natal Government Railways.</ref>
==Manufacturer== In 1880, the [[Natal Government Railways]] (NGR) placed an order for a single {{nowrap|0-6-0}} saddle-tank locomotive with [[Hunslet Engine Company]] in [[Leeds]]. It was virtually identical to the [[Durban Harbour's John Milne|engine ''John Milne'']] which had been supplied to the Harbour Board of Natal from the same manufacturer in 1879, having been built to the same design, but with some differences in detail such as those 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 [[South African Class C 4-6-0T|Class G {{nowrap|2-6-0T}}]] locomotives of 1879.<ref name="Holland 2"/><ref name="NGR Annual 1904"/><ref name="Middleton"/><ref name="NGR Railway Report 1880">''The Railway Report for year ending 31 Dec. 1880'', Natal Government Railways, p. JJ72.</ref><ref name="NGR Annual 1908">''The Railway Report for year ending 31 Dec. 1908'', Natal Government Railways, p. 39, par 14.</ref>
==Service== 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 Class K, which consisted of a potpourri of different tank locomotive types with different wheel arrangements. The Class included the [[NGR Class K 0-4-0ST|0-4-0ST locomotives of 1891]] and the surviving three of the [[NGR Class K 2-6-0T|{{nowrap|2-6-0T}} locomotives of 1877]].<ref name="NGR Annual 1906"/><ref name="NGR Annual 1908"/>
==Disposition== It is not known whether the locomotive had been scrapped or sold by 1912. 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.<ref name="Holland 2"/><ref name="SAR Renumber">''Classification of S.A.R. Engines with Renumbering Lists'', issued by the Chief Mechanical Engineer's Office, Pretoria, January 1912. (Reprinted in April 1987 by SATS Museum, R.3125-6/9/11-1000)</ref>
