The NGR Class I 2-6-2T of 1901 is a South African steam locomotive from the pre-Union era in the Natal Colony.

In 1894 the Natal Government made provision for the extension of the North Coast line from 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 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 Class I.[1]

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. In December 1895 an agreement was reached with the Natal sugar magnate Liege Hulett, representing the Zululand Railway Company, for the construction of the new line. The government stipulated that the line was to be 3 feet 6 inches Cape gauge and laid with 45 pounds per yard (22 kilograms per metre) 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.[1]

Manufacturer

It is presumed that NGR locomotives were used on the construction work until 1901, when the construction company acquired a single 2-6-2 tank locomotive from Baldwin Locomotive Works in the United States of America. The locomotive, which became the Zululand Railway no. 1, was designed and built to American specifications and narrow-gauge practice at the time and conformed to NGR practice only in respect of its bell couplers and brake gear.[1][2]

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.[1]

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.[3]

The Union of South Africa was established on 31 May 1910, in terms of the South Africa Act. One of the clauses in the Act required that the three Colonial Government railways, the Cape Government Railways, the NGR and the Central South African Railways, also be united under one single administration to control and administer the railways, ports and harbours of the Union. While the South African Railways (SAR) came into existence in 1910, the actual classification and renumbering of all the rolling stock of the three constituent railways required careful planning and was only implemented with effect from 1 January 1912.[4][5]

In 1912 the Construction Department locomotives working in Natal were considered obsolete. The locomotive was excluded from the SAR classification and renumbering schedules, renumbered to 0501 and remained unclassified. It was scrapped in March 1916.[5][6]
