Welsh 0-6-2T Locomotives
Welsh 0-6-2T locomotives were a standard steam locomotive of the railways of South Wales. Many of the independent railways used them and, at the grouping of 1923, the survivors passed into Great Western Railway (GWR) stock. The GWR perpetuated the type in the GWR 5600 Class. The other major railway company in Wales, the LNWR, also had the LNWR Webb Coal Tank Class, though this was grouped into the LMS not the GWR. Overview The railways of South Wales seem to have had a particular liking for the 0-6-2T type. This was because the nature of the work they undertook demanded high adhesive weight, plenty of power with good braking ability, but no need for outright speed, nor large tanks or bunker as the distances from pit to port were short. These Welsh locomotives were taken over by the GWR at the grouping in 1923 and many were rebuilt with GWR taper boilers. Numbering Many Welsh 0-6-2T locomotives passed into British Railways (BR) ownership in 1948 and these included (with some gap ...

British Railways
British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most of the overground rail transport in Great Britain from 1948 to 1997. It was formed from the nationalisation of the Big Four British railway companies, and was privatised in stages between 1994 and 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in January 1963, when it was formally renamed the British Railways Board. The period of nationalisation saw sweeping changes in the railway. A process of dieselisation and electrification took place, and by 1968 steam locomotives had been entirely replaced by diesel and electric traction, except for the Vale of Rheidol Railway (a narrow-gauge tourist line). Passengers replaced freight as the main source of business, and one-third of the network was closed by the Beeching cuts of the 1960s in an effort to reduce rail subsidies. On privatis ...

Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is common ...

Charles Collett
Charles Benjamin Collett (10 September 1871 – 5 April 1952) was Chief Mechanical Engineer of the Great Western Railway from 1922 to 1941. He designed (amongst others) the GWR's Castle and King Class express passenger locomotives. Education and early career Collett was educated at the Merchant Taylors' School (then at Charterhouse Square, London) and the City and Guilds College of London University. He then became an engineering pupil at Maudslay, Sons and Field, a firm that built marine steam engines. In 1893 he entered the GWR Drawing Office at Swindon as a junior draughtsman. Four years later he was put in charge of the buildings section, and in 1898 became assistant to the Chief Draughtsman. In June 1900 he was appointed Technical Inspector, and soon after Assistant Manager, at the Swindon Works. In 1912 he rose to be Manager of the Works, then in 1919 he was made Deputy Chief Mechanical Engineer of the GWR. Chief Mechanical Engineer Collett's predecessor, George Jacks ...

Standardization
Standardization or standardisation is the process of implementing and developing technical standards based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments. Standardization can help maximize compatibility, interoperability, safety, repeatability, or quality. It can also facilitate a normalization of formerly custom processes. In social sciences, including economics, the idea of ''standardization'' is close to the solution for a coordination problem, a situation in which all parties can realize mutual gains, but only by making mutually consistent decisions. History Early examples Standard weights and measures were developed by the Indus Valley civilization.Iwata, Shigeo (2008), "Weights and Measures in the Indus Valley", ''Encyclopaedia of the History of Science, Technology, and Medicine in Non-Western Cultures (2nd edition)'' edited by Helaine Selin, pp. 2254–2255, Springer, .

Brecon And Merthyr Railway
The Brecon and Merthyr Tydfil Junction Railway (B&MR) was a railway company in Wales. It was originally intended to link the towns in its name. Finding its access to Merthyr difficult at first, it acquired the Rumney Railway, an old plateway, and this gave it access to Newport docks. This changed its emphasis from rural line to mineral artery. It opened at the Brecon end to a point near Dowlais in 1863, and in 1865 it opened a disconnected section from Rhymney to Newport. In due course the company connected the two sections and reached Dowlais and Merthyr, but had to concede sharing a route with the powerful London and North Western Railway. The B&MR was always short of money, and was notable for its prodigious gradients, but it survived until the grouping of 1923, when it became part of the Great Western Railway. Its network declined steeply after 1945, and passenger operation ceased in 1962. Goods and mineral operation also lost its market, and as of 2020, only a short stub to ...

Taff Vale Railway
The Taff Vale Railway (TVR) was a standard gauge railway in South Wales, built by the Taff Vale Railway Company to serve the iron and coal industries around Merthyr Tydfil and to connect them with docks in Cardiff. It was opened in stages in 1840 and 1841. In the railway's first years, the coal mining industries expanded considerably and branches were soon opened in the Rhondda valleys and the Cynon Valley. The conveyance of coal for export and for transport away from South Wales began to dominate and the docks in Cardiff and the approach railway became extremely congested. Alternatives were sought and competing railway companies were encouraged to enter the trade. In the following decades further branch lines were built and the TVR used " motor cars" (steam railway passenger coaches) from 1903 to encourage local passenger travel. From 1922 the TVR was a constituent of the new Great Western Railway (GWR) at the grouping of the railways, imposing its own character on ...

Barry Railway
The Barry Railway Company was a railway and docks company in South Wales, first incorporated as the ''Barry Dock and Railway Company'' in 1884. It arose out of frustration among Rhondda coal owners at congestion and high charges at Cardiff Docks as well the monopoly held by the Taff Vale Railway in transporting coal from the Rhondda. In addition, the Taff Vale did not have the required capacity for the mineral traffic using the route, leading to lengthy delays in getting to Cardiff. The Barry Railway opened its main line from Trehafod in the Rhondda to Barry, Vale of Glamorgan, Barry in 1889 and its first dock was opened in the same year, with modern loading equipment. It was immediately successful and principally carried coal, the tonnage increased year on year, so that by 1910 it had overtaken Cardiff as the largest export point of South Wales coal and in 1913, a world record of shipment of 11.27 million metric tonnes of coal were exported. Later it built costly branches to c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiff Railway
From 1839 the Trustees of the Marquis of Bute, operated a large dock operation in Cardiff, the "Bute Docks". This was very successful, but was overwhelmed by the huge volume of coal exported through Cardiff. At the same time it was seen that railway companies, especially the Taff Vale Railway (TVR), were making money conveying the coal to the docks. The Bute Docks company decided to built a railway from Pontypridd to their dock; they obtained Parliamentary authority for part of the route in 1898, and changed the company name to the Cardiff Railway. To be successful, they needed to make a junction with their main rival, the TVR, at Treforest. A single mineral train traversed the junction in 1909 but legal challenges prevented any further use. The Cardiff Railway had built an expensive railway line that failed to connect with the collieries beyond Pontypridd. The company became part of the Great Western Railway (as did the TVR) in 1923. A low-key passenger service was operated, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhymney Railway
The Rhymney Railway was a railway company in South Wales, founded to transport minerals and materials to and from collieries and ironworks in the Rhymney Valley of South Wales, and to docks in Cardiff. It opened a main line in 1858, and a limited passenger service was operated in addition. The first line was dependent on the cooperation of the parallel Taff Vale Railway (TVR) for part of the transit, and this relationship was uneasy; the Rhymney Railway built an independent line to Cardiff in 1871. Better relations were created with the London and North Western Railway (LNWR), and later the Great Western Railway (GWR), and two important joint lines with the GWR were built: the Taff Bargoed line (1876) and the Quakers Yard and Merthyr Joint line (1882). Although the Rhymney Railway network was never large, it was remarkably profitable, and paid excellent dividends for most of its life. Dependent on mineral traffic for its own success, it declined in the 1970s, but the main line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taper Boiler
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer far greater heating surface area for the same overall boiler volume. The general construction is as a tank of water penetrated by tubes that carry the hot flue gases from the fire. The tank is usually cylindrical for the most part—being the strongest practical shape for a pressurized container—and this cylindrical tank may be either horizontal or verti ...
