The CGR NG 4-6-2T of 1908 is a South African steam locomotive from the pre-Union era in the Cape Colony.

In 1908 the Cape Government Railways placed two 4-6-2T Pacific type narrow gauge steam locomotives in passenger service on the Walmer branch in Port Elizabeth. In 1912 both locomotives were assimilated into the South African Railways and renumbered.^[2]^[3]^[4]

Manufacturer

Two 4-6-2 Pacific type narrow gauge tank steam locomotives were built for the Cape Government Railways (CGR) by W. G. Bagnall in 1908. The engines were equally powerful tank locomotive versions of the Type B 4-6-0 narrow gauge tender locomotive, also built by Bagnall, but with Walschaerts instead of Stephenson valve gear. They were not classified and were numbered 42 and 43.^[3]

Service

Cape Government Railways

Both locomotives were placed in service on the Walmer narrow gauge branchline out of Port Elizabeth.^[3] The passenger-only branchline was opened from Valley Junction near Port Elizabeth to the suburb of Walmer in 1906 and was used by up to 22 trains per day.^[5]

South African Railways

The Union of South Africa was established on 31 May 1910, in terms of the South Africa Act, enacted by the Parliament of the United Kingdom. One of the clauses in the Act required that the three Colonial Government railways, the CGR, the Natal Government Railways 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.^[2]^[6]

In 1912 the two locomotives were renumbered no. NG33 and NG34 on the SAR, with the NG number prefix identifying them as narrow gauge locomotives in the SAR registers. They remained in service on the Walmer branch for the duration of their service lives until the line was closed in 1929 and they were withdrawn from service, shortly before a classification system for narrow gauge locomotives were to be introduced by the SAR.^[3]
