The CGR 3rd Class 4-4-0 of 1901 is a South African steam locomotive from the pre-Union era in the Cape Colony.
In 1901 the Cape Government Railways placed another six 3rd Class Wynberg Tender locomotives with a 4-4-0 American type wheel arrangement in suburban service in Cape Town. They were a heavier and more powerful version of the locomotives of 1898.[1][2]
Manufacturer
Six more 3rd Class Wynberg Tender passenger locomotives entered service on the Cape Government Railways (CGR) in 1901 for suburban service in Cape Town. They were built by Sharp, Stewart and Company and numbered in the range from 6 to 11.[1][2]
These locomotives were very similar in design to the first six of 1898, but larger and more powerful. They were built for speed and had the largest coupled wheels of any locomotive on the CGR to date, at 60 inches (1,520 millimetres) diameter. In later years this driving wheel size became the accepted size for mixed traffic and general purpose locomotives on mainline service in South Africa. During the rest of the steam era in South Africa only four locomotive types were to be introduced with larger driving wheels, post-delivery modifications excluded.[1]
Service
Cape Government Railways
These locomotives were also known as Wynberg Tenders. They were also delivered with reverse running in mind, with a weatherboard mounted on the tender front to protect the crew from the elements when running tender first. These weatherboards were later removed, possibly when a turntable was constructed at the Simon's Town terminal.[1]

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.[3][4]
In 1912 the six locomotives were considered obsolete by the SAR, designated Class 03 and renumbered by having the numeral 0 prefixed to their existing numbers. In SAR service they continued to work suburban trains. Despite being considered obsolete, all six survived until c. 1918, when two were withdrawn from service. The other four survived in service until after 1931.[2][4]
