The CGR 1st Class 2-6-0 of 1879 is a South African steam locomotive from the pre-Union era in the Cape Colony.
In 1879 and 1880 the Cape Government Railways placed ten 2-6-0 Mogul type locomotives, built by Beyer, Peacock and Company, in freight service on the Cape Western system. They were also designated 1st Class when a classification system was adopted.[1][3]
Manufacturer
Six 2-6-0 Mogul type tender goods locomotives were delivered to the Cape Government Railways (CGR) from Beyer, Peacock and Company in 1879, numbered in the range from W27 to W32 for the Western System. Another four were delivered the following year, numbered in the range from W39 to W42. Like the Beyer, Peacock and Avonside locomotives of 1876 and the pre-modification Kitson locomotives of 1876, they were equipped with six-wheeled tenders.[1][3]
While they were similar in appearance to the locomotives of 1876, there were some major differences. The steam dome was located further forward from the cab, similar to that of the Kitson locomotives. The leading wheels were located much further forward from the coupled wheels at a 5 feet 6 inches (1.676 metres) wheelbase, compared to 3 feet 7 inches (1.092 metres) on the Beyer, Peacock and Avonside locomotives of 1876. In addition, the cylinders were mounted at a downward inclination towards the driving wheelset.[1][2]
While they were also acquired as goods locomotives, they were used on all kinds of traffic. All these locomotives were later designated 1st Class when a locomotive classification system was introduced by the CGR.[1]
Service
Cape Government Railways
At the time these locomotives entered service in 1879, the Western System line from Cape Town was completed to Montagu Road, which had been reached in 1877, and work on the section to Beaufort West was completed as far as Fraserburg Road. They saw service on all parts of the Western system, working out of Cape Town deeper into the Karoo as the line was being extended. The line was opened to Beaufort West on 5 February 1880 and the connection with the Midland System was made at De Aar on 31 March 1884.[1][4]
Oranje-Vrijstaat Gouwerment-Spoorwegen
Towards the end of 1896 four of these locomotives were sold to the Oranje-Vrijstaat Gouwerment-Spoorwegen (OVGS), where they were designated 2nd Class.[1]
None of these four survived to be taken onto the South African Railways (SAR) roster in 1912.[5]
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][5]
Only no. 40 was still in CGR service to be taken onto the SAR roster in 1912. It was considered obsolete by the SAR, designated Class 01 and renumbered by having the numeral 0 prefixed to its number. It was withdrawn from service by 1918.[1][3][5]
Renumbering
All these locomotives were renumbered at times during the CGR era. By 1886 the system prefixes had been done away with and by 1888 the first six locomotives were renumbered to the range from 43 to 48. The works numbers, year in service, original numbers, renumberings and disposition of the Cape 1st Class Moguls of 1879 are shown in the table.[1][3][5]

Nyasaland Railways
In his book Steam Locomotives of the South African Railways, Volume 1: 1859-1910, D.F. Holland states that four of these locomotives, numbers W27, W28, W30 and W31, by that time renumbered to 43, 44, 46 and 47 respectively, were sold to the Nyasaland Railways at some stage between 1904 and 1912.[1]
However, the early locomotives in Nyasaland are well documented and no reference exists to locomotives obtained from the CGR. The first railway in Nyasaland was the Shire Highlands Railway (SHR), on which construction started in 1904 and which was opened in 1908. The second railway was the Central African Railway (CAR), on which Pauling & Co. started construction in 1913. Nyasaland Railways was only formed in 1930 to amalgamate the SHR and CAR.[6]
