CGR 1st Class 4-4-0T
The Cape Government Railways 1st Class 4-4-0T 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 4-4-0 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.
Seven 4-4-0 side-tank locomotives were built for the Cape Government Railways (CGR) 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 900 imperial gallons (4,090 litres). They were all designated 1st Class when a locomotive classification system was introduced by the CGR.
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.
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 6 long tons (6.1 tonnes) 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.
