South African Class 10 4-6-2
The South African Railways Class 10 4-6-2 of 1904 was a steam locomotive from the pre-Union of South Africa, Union era in Transvaal Colony. In July 1904, the Central South African Railways placed fifteen Class 10 steam locomotives with a 4-6-2, Pacific type wheel arrangement in service. In 1912, when they were assimilated into the South African Railways, they were renumbered but retained their Class 10 designation.Espitalier, T.J.; Day, W.A.J. (1945).

Central South African Railways
The Central South African Railways (CSAR) was from 1902 to 1910 the operator of public railways in the Transvaal Colony and Orange River Colony in what is now South Africa. During the Anglo-Boer War, as British forces moved into the territory of the Orange Free State and the South African Republic, the Orange Free State Government Railways, the Netherlands-South African Railway Company and the Pretoria-Pietersburg Railway were taken over by the Imperial Military Railways under Lieutenant-Colonel Sir Percy Girouard. After the war had ended, the Imperial Military Railways became the Central South African Railways in July 1902, with Thomas Rees Price as general manager. With the creation of the Union of South Africa in 1910, the CSAR was merged with the Cape Government Railways and the Natal Government Railways to form the South African Railways, which is now Transnet Freight Rail Transnet Freight Rail is a South African rail transport company, formerly known as Spoornet.

South African Type XM3 Tender
The South African type XM3 tender was a steam locomotive tender from the pre-Union era in the Transvaal. The Type XM3 tender entered service in 1904, as tenders to the Pacific type steam locomotives which were acquired by the Central South African Railways in that year. In 1912, these locomotives retained their Class 9 designation on the South African Railways.South African Railways & Harbours/Suid Afrikaanse Spoorweë en Hawens (15 Aug 1941).

Cape Government Railways
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. History Private railways The first railways at the Cape were privately owned. The Cape Town Railway and Dock Company started construction from Cape Town in 1859, reaching Eerste River by 1862 and Wellington by 1863. Meanwhile, by 1864, the Wynberg Railway Company had connected Cape Town and Wynberg. For the moment, railway development at the Cape did not continue eastwards beyond Wellington because of the barrier presented by the mountains of the Cape Fold Belt. Formation of CGR The discovery of diamonds, and the consequent rush to Kimberley that started in 1871, gave impetus to the development of railways in South Africa. Shortly afterwards, in 1872, the Cape Colony attained responsible government under the leadership of Prime Minister John Molteno, who presented plans for an enormous network of railways t ...

South African Class 5A 4-6-2
The South African Railways Class 5A 4-6-2 of 1903 was a steam locomotive from the pre-Union era in the Cape of Good Hope. In 1903, the Cape Government Railways placed two Karoo Class steam locomotives with a Pacific type wheel arrangement in passenger service. In 1912, when they were assimilated into the South African Railways, they were renumbered and designated Class 5A.Espitalier, T.J.; Day, W.A.J. (1944).

Transvaal Colony
The Transvaal Colony () was the name used to refer to the Transvaal region during the period of direct British rule and military occupation between the end of the Second Boer War in 1902 when the South African Republic was dissolved, and the establishment of the Union of South Africa in 1910. The borders of the Transvaal Colony were larger than the defeated South African Republic (which had existed from 1856 to 1902). In 1910 the entire territory became the Transvaal Province of the Union of South Africa. History Both the Boer republics, the South African Republic (ZAR) and the Orange Free State were defeated in the Anglo-Boer War and surrendered to the UK. The peace treaty (Treaty of Vereeniging) contained the following terms: # That all burghers of the ZAR and Orange Free State lay down their arms and accept King Edward VII as their sovereign. # That all burghers outside the borders of the ZAR and Orange Free State, upon declaring their allegiance to the King, be transpo ...

Union Of South Africa
The Union of South Africa ( nl, Unie van Zuid-Afrika; af, Unie van Suid-Afrika; ) was the historical predecessor to the present-day Republic of South Africa. It came into existence on 31 May 1910 with the unification of the Cape, Natal, Transvaal, and Orange River colonies. It included the territories that were formerly a part of the South African Republic and the Orange Free State. Following World War I, the Union of South Africa was a signatory of the Treaty of Versailles and became one of the founding members of the League of Nations. It was conferred the administration of South West Africa (now known as Namibia) as a League of Nations mandate. It became treated in most respects as another province of the Union, but it never was formally annexed. Like Canada, Australia and New Zealand, the Union of South Africa was a self-governing dominion of the British Empire. Its full sovereignty was confirmed with the Balfour Declaration of 1926 and the Statute of Westminster 1931. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Railways
Transnet Freight Rail is a South African rail transport company, formerly known as Spoornet. It was part of the South African Railways and Harbours Administration, a state-controlled organisation that employed hundreds of thousands of people for decades from the first half of the 20th century and was widely referred to by the initials SAR&H (SAS&H in Afrikaans). Customer complaints about serious problems with Transnet Freight Rail's service were reported in 2010. Its head office is in Inyanda House in Parktown, Johannesburg. History Railways were first developed in the area surrounding Cape Town and later in Durban around the 1840s. The first line opened in Durban on 27 June 1850. The initial network was created to serve the agricultural production area between Cape Town and Wellington. The news that there were gold deposits in the Transvaal Republic moved the Cape Colony Government (supported by British Government) to link Kimberley as soon as possible by rail to Cape Town ...

Janney Coupler
Janney couplers are a semi-automatic form of railway coupling that allow rail cars and locomotives to be securely linked together without rail workers having to get between the vehicles. They are also known as American, AAR, APT, ARA, MCB, knuckle, Buckeye, tightlock (in the UK), Henricot (in Belgium) or Centre Buffer Couplers. Background Janney couplers were first patented in 1873 by Eli H. Janney (). Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; Beard's patents were granted 23 November 1897, which then sold for approximately $50,000, and granted 16 May 1899. In the UK, several versions of Janney couplers are fitted to a limited number of coaches, multiple units, wagons and locomotives. Janney Type E, Type F Interlock, and Type H tightlock couplings are compatible subtypes, each intended for specific rail car types. Prior to the formation of the Association of American Railroads (AAR) these were known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Coupling
A coupling (or a coupler) is a mechanism typically placed at each end of a railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Buffers and chain The basic type of coupling on railways following the British tradition is the bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piston Valve (steam Engine)
Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive. They control the admission of steam into the cylinders and its subsequent exhausting, enabling a locomotive to move under its own power. The valve consists of two piston heads on a common spindle moving inside a steam chest, which is essentially a mini-cylinder located either above or below the main cylinders of the locomotive. Overview In the 19th century, steam locomotives used slide valves to control the flow of steam into and out of the cylinders. In the 20th century, slide valves were gradually superseded by piston valves, particularly in engines using superheated steam. There were two reasons for this: * It is difficult to lubricate slide valves adequately in the presence of superheated steam * With piston valves, the steam passages can be made shorter. This, particularly following the work of André Chapelon, reduces resistance to the flow of steam and improves eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walschaerts Valve Gear
The Walschaerts valve gear is a type of valve gear used to regulate the flow of steam to the pistons in steam locomotives, invented by Belgium, Belgian railway mechanical engineering, engineer Egide Walschaerts in 1844. The gear is sometimes named without the final "s", since it was incorrectly patented under that name. It was extensively used in steam locomotives from the late 19th century until the end of the steam era. History The Walschaerts valve gear was slow to gain popularity. The Stephenson valve gear remained the most commonly used valve gear on 19th-century locomotives. However, the Walschaerts valve gear had the advantage that it could be mounted entirely on the outside of the locomotives, leaving the space between the locomotive frame, frames clear and allowing easy access for service and adjustment, which resulted in it being adopted in some articulated locomotives. The first locomotive fitted with the Walschaerts valve gear was built at the Belgian Tubize worksh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safety Valve
A safety valve is a valve that acts as a fail-safe. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would be a rupture disk. Safety valves were first developed for use on steam boilers during the Industrial Revolution. Early boilers operating without them were prone to explosion unless carefully operated. Vacuum safety valves (or combined pressure/vacuum safety valves) are used to prevent a tank from collapsing while it is being emptied, or when cold rinse water is used after hot CIP (clean-in-place) or SIP (sterilization-in-place) procedures. When sizing a vacuum safety valve, the calculation method is not defined in any norm, particularly in the hot CIP / cold water scenario, but some manu ...
