CGR 1st Class 4-4-0T


The Cape Government Railways 1st Class of 1875 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.
In 1875, the Cape Government Railways placed seven tank locomotives with a American type wheel arrangement in service on its Cape Western and Cape Midland systems. Four more entered service in 1880, but these were delivered as tank-and-tender locomotives with optional water tenders. They were the first Cape gauge mainline engines to enter service in South Africa.

Manufacturers

Seven 4-4-0 side-tank locomotives were built for the Cape Government Railways by Robert Stephenson and Company in 1875, numbered in the range from W3 to W6 in the Western System's number range and M11 to M13 in the Midland System's number range.
Since they were found to be fast and reliable engines, four more were delivered in 1880, built by Neilson and Company and numbered in the range from M40 to M43 in the Midland System's number range. They were practically identical to the previous seven, but sported some minor improvements and were built as tank-and-tender locomotives, equipped with small optional four-wheeled water tenders with a capacity of. They were all designated 1st Class when a locomotive classification system was introduced by the CGR.

Characteristics

The locomotive had a round-topped firebox. The cylinders were inclined and arranged outside the engine frame, while the slide valves were actuated by Stephenson Link motion. The cab sides of the early locomotives were not enclosed, but were equipped with canvas roller blinds to offer the crew some protection against the elements.
The later versions of the locomotive had enclosed cab sides. These engines were slightly longer with larger water tanks and had larger firebox and boiler heating surfaces, with an increased boiler pressure.

Service

Cape Government Railways

These were the first Cape gauge engines to enter mainline service in South Africa. In service, the locomotives were operated with or without the tenders, as circumstances demanded. In practice, they were used in the tank engine configuration while performing shunting work and in the tank-and-tender configuration when an increased coal and water supply was required while working over longer distances. Since the tender had no coal bunker, bags of additional coal were often carried on top of the tender.
The locomotives worked both passenger and mixed goods trains. They performed fairly well with the original four-wheeled carriages which were in use while passenger numbers were still limited. With increasing passenger traffic, heavier carriages on bogies were introduced, which led to the locomotives being withdrawn from mainline work and relegated to shunting work, a role in which they remained useful for many years.

Metropolitan & Suburban Railway

When the Green and Seapoint Company was established in 1887 with the object to construct a private suburban railway line to Sea Point in Cape Town, two of these locomotives, numbers 3 and 4, were acquired from the CGR for use as construction engines.
Following two bankruptcies, the line was eventually opened on 1 September 1892 by a third company, the Metropolitan and Suburban Railway Company, under the chairmanship of Mr. John Walker. The two locomotives were then employed as passenger locomotives. The line was not financially viable, however, and the Metropolitan and Suburban also went into liquidation on 19 July 1898. The railway and its operations were eventually taken over by the Cape government and the Sea Point line was re-opened by the CGR in December 1905.

South African Railways

When the Union of South Africa was established on 31 May 1910, the three Colonial government railways were united under a single administration to control and administer the railways, ports and harbours of the Union. Even though the South African Railways and Harbours 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.
According to some sources, two of these locomotives, one from each batch with numbers 413 and 441, were sold to the Nyasaland Railways at some stage. Serious doubt exists, however, that these engines ever went to Nyasaland, since no evidence of such a sale has come to light and since both locomotives are referred to in the South African Railways renumbering and classification lists of 1912.
By 1904, five of the locomotives had been scrapped or sold and, by 1912, the only survivors were the two locomotives which had allegedly earlier been sold to Nyasaland and which, at the time, were both found to be rostered at Uitenhage on the Midland system. They were considered obsolete by the SAR and were excluded from the classification schedules, but were renumbered by having the numeral "0" prefixed to their existing numbers.

Renumbering

All these locomotives were renumbered at least once, whenever the CGR adopted a new numbering system. By 1886, the system prefixes had been dropped, with the "W" omitted from the locomotive numbers on the Western System and the "M" replaced by the numeral "1" on the Midland. Further renumbering was applied to the Midland locomotives by 1890 and again by 1896, when first the leading numeral "1" was replaced by the numeral "2" by 1890, and again when the leading numeral "2" was, in turn, replaced by the numeral "4" by 1896.
