The CGR 2nd Class 4-4-0T of 1882 is a South African steam locomotive from the pre-Union era in the Cape Colony.
In 1882 the Cape Government Railways placed six 2nd Class tank locomotives with a 4-4-0 American type wheel arrangement in service on its suburban passenger trains out of Cape Town. Five more of these Wynberg Tanks entered service in 1888 and 1891.[1]
Manufacturers
Six 4-4-0T locomotives were built for the Cape Government Railways (CGR) by Neilson and Company in 1882, numbered in the range from W89 to W94 in the Cape Western system’s number range. They entered service on suburban passenger trains working out of Cape Town to the southern and northern suburbs. Two more, numbered 27 and 28, were delivered from the same builders in 1888 and another three, numbered in the range from 18 to 20, from Dübs and Company in 1891.[1]
Wynberg Tanks
Since the southern suburban line ran to a terminus at Wynberg, the locomotives became known as the Wynberg Tanks. Their official CGR classification was as 2nd Class in spite of the fact that they were of a different wheel arrangement and configuration than existing Cape locomotives with the same class designation, the 2-6-2 tank-and-tender 2nd Class of 1875.[1][2]
Characteristics
The first six locomotives were delivered with coupled wheels of 48 1⁄2 inches (1,230 millimetres) diameter, but the diameter was subsequently increased to 49 inches (1,240 millimetres) when the wheels were retyred. The two batches of 1888 and 1891 were delivered with the larger diameter driving wheels.[1]
Since the enclosed cabs offered ample protection from the elements and the locomotives performed well, they were popular with the enginemen. The CGR general manager’s report for 1889 mentioned that locomotive no. 27, which had been placed in service in March 1888, had worked continuously on the heaviest and fastest trains in the Colony and had run 58,123 miles (93,540 kilometres) during the year in question, only having been taken out of service to have worn tyres replaced.[1]
Service
Cape Government Railways
The first batch of locomotives was renumbered by 1887 and again in 1888 when the CGR adopted new locomotive numbering systems. In addition to the known numbering and renumbering, there appears to have been an "intermediate" CGR numbering system at some stage between 1884 and the renumberings of the late 1880s. Apart from photographic evidence, hardly any information about this numbering system has been found as yet. An example is the main picture of a Wynberg Tank, possibly no. W93, bearing the number 116 that does not fit in with any of the known numbers of these locomotives.[3][4][5]

After the Metropolitan and Suburban Railway Company went into liquidation and the railway and its operations were taken over by the Cape government in December 1905, two of the Wynberg Tanks were transferred to the Sea Point section. The locomotives remained on suburban passenger service on the Wynberg and Sea Point lines until the increasing loads became too heavy for them to handle. They were then placed in shunting service and also hauled the lighter passenger trains on the Milnerton branchline.[1][3][6]
South African Railways
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 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.[4][6]
With the exception of no. W89-93-21 that had been scrapped at some time between 1888 and 1891, all these locomotives were still in service in 1912. Since the SAR considered them obsolete, they were renumbered by having a 0 prefix added to their existing numbers. They were classified as Class 02 on the SAR and remained in service until 1916, when they were withdrawn.[1][7]
