The '''Natal Government Railways Class I 2-6-2T''' of 1901 was a South African steam locomotive from the pre-[[Union of South Africa|Union]] era in the [[Colony of Natal]].
In 1894, the Natal Government made provision for the extension of the North Coast line from [[Verulam, KwaZulu-Natal|Verulam]] to the [[Tugela River]]. The Zululand Railway Company was contracted for the construction of the line in 1895. In 1901, the company acquired one {{nowrap|2-6-2}} side-tank locomotive as construction engine. Upon completion of the line in 1903, the locomotive was taken onto the roster of the [[Natal Government Railways]] and designated {{nowrap|Class I}}.<ref name="Holland 1">{{Holland-Vol 1|pages=96-97}}</ref><ref name="SAR&H Sep 1944">Espitalier, T.J.; Day, W.A.J. (1944). ''The Locomotive in South Africa – A Brief History of Railway Development. Chapter III – Natal Government Railways'' (Continued). South African Railways and Harbours Magazine, September 1944. p. 671.</ref>
==Zululand Railway Company== Provision for the extension of the North Coast line from Verulam to the Tugela River was made by Act 34 of 1894 of the [[Colony of Natal]]. On 19 December 1895, an agreement was reached with the Natal sugar magnate [[Liege Hulett|James Liege Hulett]], representing the Zululand Railway Company, for the construction of the new line.<ref name="Holland 1"/><ref name="SAR&H Sep 1944"/>
The government stipulated that the line was to be 3 feet 6 inches [[Cape gauge]] and laid with {{convert|45|lb/yd|abbr=off}} steel rail. The agreement further stipulated that, upon its completion, the line would be taken over as part of the [[Natal Government Railways]] (NGR) system.<ref name="Holland 1"/><ref name="SAR&H Sep 1944"/>
==Manufacturer== In 1901, the construction company acquired a single {{nowrap|2-6-2T}} locomotive from [[Baldwin Locomotive Works]] in the [[United States]] of America, for use as construction engine. The locomotive, which became the Zululand Railway no. 1, was designed and built to American specifications and narrow-gauge practice at the time and, as a result, conformed to NGR practice only in respect of its [[Railway coupling#Johnston coupler|Johnston link-and-pin]] couplers and brake gear.<ref name="Holland 1"/><ref name="SAR&H Sep 1944"/><ref name="Dulez 150">{{Dulez 150|pages=25–26}}</ref>
==Characteristics== The cylinders were arranged outside the [[Locomotive frame#Bar frames|bar frame]] while the [[slide valve]]s, arranged above the cylinders, were actuated by [[Stephenson valve gear|Stephenson link motion]] through rocker shafts. Two sandboxes were mounted atop the boiler, fore and aft of the steam dome.<ref name="SAR&H Sep 1944"/>
==Service== The Tugela line was opened to traffic in 1903 and Zululand no. 1 was taken onto the NGR roster, where it was allocated no. 512.<ref name="Holland 1"/><ref name="SAR&H Sep 1944"/>
It was later renumbered to 501 and was allocated to the Construction Department of the NGR. When a classification system was introduced at some stage between 1904 and 1908, it was designated NGR Class I.<ref name="NGR Annual 1908">''The Railway Report for year ending 31 Dec. 1908'', Natal Government Railways, p. 39, par 14.</ref>
When the [[Union of South Africa]] was established on 31 May 1910, the three Colonial government railways ([[Cape Government Railways]], NGR and [[Central South African Railways]]) were united under a single administration to control and administer the railways, ports and harbours of the Union. Although the South African Railways and Harbours came into existence in 1910, the actual classification and renumbering of all the rolling stock of the three constituent railways were only implemented with effect from 1 January 1912.<ref name="SAR History">''The South African Railways – Historical Survey''. Editor George Hart, Publisher Bill Hart, Sponsored by Dorbyl Ltd., Published c. 1978, p. 25.</ref><ref name="SAR Renumber"/>
In 1912, the Construction Department locomotives in Natal were considered obsolete. The locomotive was excluded from the South African Railways classification and renumbering schedules, renumbered to 0501 and remained unclassified. It was scrapped in March 1916.<ref name="SAR Renumber">''Classification of S.A.R.
