The South African Railways Class Experimental 4 2-8-2 of 1903 was a steam locomotive from the pre-Union era in the Cape of Good Hope.
The Union of South Africa is the historical predecessor to the present-day Republic of South Africa. It came into being on 31 May 1910 with the unification of the Cape Colony, the Natal Colony, the Transvaal, and the Orange River Colony. It included the territories that were formerly a part of the South African Republic and the Orange Free State.
The Cape of Good Hope, also known as the Cape Colony, was a British colony in present-day South Africa, named after the Cape of Good Hope. The British colony was preceded by an earlier Dutch colony of the same name, the Kaap de Goede Hoop, established in 1652 by the Dutch East India Company. The Cape was under Dutch rule from 1652 to 1795 and again from 1803 to 1806. The Dutch lost the colony to Great Britain following the 1795 Battle of Muizenberg, but had it returned following the 1802 Peace of Amiens. It was re-occupied by the UK following the Battle of Blaauwberg in 1806, and British possession affirmed with the Anglo-Dutch Treaty of 1814.
In 1903, the Cape Government Railways placed two 9th Class steam locomotives with a 2-8-2 Mikado type wheel arrangement in service. In 1912, when they were assimilated into the South African Railways, they were renumbered and designated Class Experimental 4. [1] [2] [3] [4]
The Cape Government Railways (CGR) was the government-owned railway operator in the Cape Colony from 1874 until the creation of the South African Railways (SAR) in 1910.
Under the Whyte notation for the classification of steam locomotives, 2-8-2 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles and two trailing wheels on one axle, usually in a trailing truck. This configuration of steam locomotive is most often referred to as a Mikado, frequently shortened to Mike.
The Cape 9th Class locomotive was designed by H.M. Beatty, the Locomotive Superintendent of the Cape Government Railways (CGR) from 1896 to 1910. They were the first South African locomotives to have a 2-8-2 Mikado wheel arrangement and they were built with bar frames, had Stephenson’s Link valve gear and used saturated steam. Two locomotives were delivered by Kitson and Company in 1903, numbered 805 and 806. [1] [2] [3] [4]
The Stephenson valve gear or Stephenson link or shifting link is a simple design of valve gear that was widely used throughout the world for all kinds of steam engines. It is named after Robert Stephenson but was invented by his employees.
Kitson and Company was a locomotive manufacturer based in Hunslet, Leeds, West Yorkshire, England.
The locomotives were delivered with Type XE1 tenders. Their intermediate and driving coupled wheels were flangeless to allow them to cope with tight curves, such as in turnouts. [2] [5] [6]
The South African type XE1 tender was a steam locomotive tender from the pre-Union era in the Cape of Good Hope.
With these locomotives, Beatty attempted to combine the best design features and good qualities of his Cape 8th Class 2-8-0 locomotive of 1901 with the improved steaming which was obtained from a wide firegrate. In many respects, they were enlarged versions of the two Cape 6th Class 2-6-2 locomotives which were delivered by Kitson in the same year, with many features in common. [1]
The South African Railways Class 8X 2-8-0 of 1901 was a steam locomotive from the pre-Union era in the Cape of Good Hope.
The South African Railways Class 6Y 2-6-2 of 1903 was a steam locomotive from the pre-Union era in the Cape of Good Hope.
They were placed in service on the mainline between De Aar and Kimberley. [1] [2] [4]
De Aar is a town in the Northern Cape, South Africa. It has a population of around 42,000 inhabitants.
Kimberley is the capital and largest city of the Northern Cape Province of South Africa. It is located approximately 110 km east of the confluence of the Vaal and Orange Rivers. The city has considerable historical significance due to its diamond mining past and the siege during the Second Boer War. British businessmen Cecil Rhodes and Barney Barnato made their fortunes in Kimberley, and Rhodes established the De Beers diamond company in the early days of the mining town.
In comparison with the Cape 8th Class, it was found that their operational and maintenance costs were much higher without any advantage in terms of efficiency. As a result, no more of the type were ordered. [1] [2] [4]
When the Union of South Africa was established on 31 May 1910, the three Colonial government railways (CGR, Natal Government Railways and Central South African Railways) were united under a single administration to control and administer the railways, ports and harbours of the Union. Although 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 were only implemented with effect from 1 January 1912. [3] [7]
In 1912, the locomotives were designated Class Experimental 4 and renumbered to 910 and 911 on the SAR. They were withdrawn from service and scrapped in 1930. [1] [2] [3] [4] [8]

The South African Railways Class 14C includes four batches of the same locomotive type, all initially designated Class 14C. Through reboilerings, rebalancings and cylinder bushings during its service life, this single class eventually ended up as six distinct locomotive classes with two boiler types and a multitude of axle load and boiler pressure configurations.
