The CGR 5th Class 4-6-0 of 1890 is a South African steam locomotive from the pre-Union era in the Cape Colony.
In 1890 the Cape Government Railways placed twenty 5th Class tender locomotives with a 4-6-0 Tenwheeler type wheel arrangement in mainline service on its Midland and Western Systems.[1]
Manufacturer
The Cape Government Railways 5th Class 4-6-0 Tenwheeler type locomotives were delivered from Dübs and Company in 1890. Of the twenty locomotives, eighteen went to the Midland System to work out of Port Elizabeth, numbered in the range from 291 to 308. The other two, numbered 119 and 120, went to the Western System for service in the Karoo on the section between Touws River and Beaufort West.[1]
Characteristics
The locomotive was a larger and improved version of the earlier 4th Class 4-6-0TT locomotive. It had 46 inches (1,170 millimetres) diameter coupled wheels and, compared to the second batch of 5th Class locomotives that were delivered a year later in 1891, it had a short smokebox with the chimney so close to the front of the smokebox that the headlight had to be mounted on a platform attached to the front of the smokebox.[1][3]
Service
Cape Government Railways
The 5th Class proved to be very useful engines that were considered the first really efficient all-round locomotives in the Colony and they were used wherever the mainline had severe gradients and curves. Because of their greater power, the older 4th Class locomotives were gradually relegated to secondary duties.[1]
Oranje-Vrijstaat Gouwerment-Spoorwegen
In late 1896 eight of the Midland System's locomotives were sold to the newly established Oranje-Vrijstaat Gouwerment-Spoorwegen (OVGS), where they were designated 5th Class K and renumbered in the range from 41 to 48.[1][4]
Central South African Railways
During the South African War control of all railways in the Orange Free State was taken over by the Imperial Military Railways. At the end of the war in 1902, the eight ex-OVGS locomotives came onto the roster of the Central South African Railways (CSAR), where they were renumbered in the range from 318 to 325. In 1904 the CSAR reboilered two of these locomotives, no. 319 and 322, with larger boilers and Belpaire fireboxes that were equipped with Drummond tubes.[1][2]
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 CSAR, 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]
By 1912 sixteen of these locomotives survived, twelve on the CGR and four, including the two that had been reboilered, on the CSAR. They were considered obsolete by the SAR, designated Class 05 and renumbered by having the numeral 0 prefixed to their existing numbers.[4]
In spite of being considered obsolete, some of the Class 05 locomotives survived as shunting engines in SAR service for another four decades, with some even getting reboilered while in SAR service. One confirmed example is no. 0506, which was still equipped with boiler no. 7244 of 1924 when it was withdrawn from service in the 1950s.[6]
The Class 05 locomotives were the last obsolete engines to be still in SAR service when they were eventually withdrawn in 1953.[2]
