GWR 850 Class
The GWR Class 850 was an extensive class of small locomotives designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway between 1874 and 1895. Aptly described as the GWR equivalent of the LB&SCR "Terrier" Class of William Stroudley, their wide availability and lively performance gave them long lives, and eventually they were replaced from 1949 by what were in essence very similar locomotives, the short-lived 1600 Class of Frederick Hawksworth, which in the headlong abandonment of steam outlived them by a mere seven years or so. Construction The 850 Class originally consisted of 50 locomotives comprising 48 new and two rebuilds. The rebuilds, Nos. 93 and 94, were supplied in 1875 and 1877 as renewals of the original Gooch locomotives of 1860. Later, as locomotives were rebuilt, the 120 locomotives of the 1901 class were incorporated into the 850 class to make a total of 170 locomotives. It has been claimed that Nos. 1216-1227 wer ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

The Chiltern Hundreds (film)
''The Chiltern Hundreds'' (released in the U.S. as ''The Amazing Mr. Beecham'') is a 1949 British politically-themed comedy film directed by John Paddy Carstairs, adapting William Douglas Home's 1947 play of the same name and starring Lana Morris, David Tomlinson and Cecil Parker. Synopsis Viscount Pym (David Tomlinson) – whilst on National Service – gets leave from the British Army on the pretext of standing for Parliament as a Conservative Party candidate in his home constituency, held by his family for generations. The request is a ruse to enable Pym to marry his wealthy American fiancée June Farrell (Helen Backlin) while she is still in England and before she has to return home to America. His master plan backfires when he finds himself swept into the election campaign and beaten by the more politically experienced Mr Cleghorn ( Tom Macaulay), the Labour Party candidate. After losing the election, his family take the news calmly, but his fiancée is mortified, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GWR 2021 Class
The GWR 2021 Class was a class of 140 steam locomotives. They were built at the Wolverhampton railway works of the Great Western Railway between 1897 and 1905. 1897 was the very year of George Armstrong's retirement, so it is uncertain if the design should be attributed to him or to his superior at Swindon, William Dean. In fact the 2021s were simple enlargements of the Armstrong-designed 850 class of 1874. The changes were fundamentally confined to a longer wheelbase to permit fitting of a larger firebox. History The class was built in eight batches: * 2021-2030 (Lot D3, 1897) * 2031-2040 (Lot F3, 1897–8) * 2041-2060 (Lot G3, 1898–9) * 2061-2080 (Lot H3, 1899–1900) * 2081-2100 (Lot J3, 1900–01) * 2101-2120 (Lot K3, 1902–3) * 2121-2140 (Lot L3, 1903–4) * 2141-2160 (Lot M3, 1904–5) Rebuilding with Belpaire fireboxes commenced in the early years of the Churchward era. Unsuccessful attempts to form a saddle tank around the firebox directly led to the switch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddington Station
Paddington, also known as London Paddington, is a Central London railway terminus and London Underground station complex, located on Praed Street in the Paddington area. The site has been the London terminus of services provided by the Great Western Railway and its successors since 1838. Much of the main line station dates from 1854 and was designed by Isambard Kingdom Brunel. Paddington is the London terminus of the Great Western Main Line; passenger services are primarily operated by Great Western Railway, which provides the majority of commuter and regional passenger services to west London and the Thames Valley region as well as long-distance intercity services to South West England and South Wales. The station is also the eastern terminus for Heathrow Express and the western terminus for Elizabeth line services from Shenfield. Elizabeth line services also run through Paddington westwards to Reading, Heathrow Terminal 5, and Heathrow Terminal 4, and eastwards to Abbey Wood ...

Cornwall Minerals Railway
The Cornwall Minerals Railway owned and operated a network of of standard gauge railway lines in central Cornwall, England, United Kingdom. It started by taking over an obsolescent horse-operated tramway in 1862, and it improved and extended it, connecting Newquay and Par Harbours, and Fowey. Having expended considerable capital, it was hurt by a collapse in mineral extraction due to a slump in prices. Despite its title, it operated a passenger service between Newquay and Fowey. After a period in bankruptcy it returned to normal financial arrangements and acquired the moribund Lostwithiel and Fowey line. In 1896 it sold its line to the Great Western Railway. Its main passenger line from Par to Newquay is still in use as the Atlantic Coast Line, and also carries some mineral traffic, but the Par to Fowey line has been converted to a private road. Before the CMR Treffry Joseph Austen (1782 - 1850) of Fowey inherited considerable lands and mineral resources in central Cornw ...

Tender (locomotive)
A tender or coal-car (US only) is a special rail vehicle hauled by a steam locomotive containing its fuel (wood, coal, oil or torrefied biomass) and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so their tenders are necessary to keep them running over long distances. A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board the locomotive itself are called tank locomotives. A corridor tender is a locomotive tender with a passageway to one side, allowing crew changes on the fly. A brake tender is a tender that is heavy and used (primarily) to provide greater braking efficiency. General functions The largest steam locomotives are semi-permanently coupled by a drawbar to a tender that carries the water and fuel. The fuel source used depends on what is economically available locally. In the UK and parts of Europe, a plentiful supply of coal made th ...

Belpaire Firebox
The Belpaire firebox is a type of firebox used on steam locomotives. It was invented by Alfred Belpaire of Belgium in 1864. Today it generally refers to the shape of the outer shell of the firebox which is approximately flat at the top and square in cross-section, indicated by the longitudinal ridges on the top sides. However, it is the similar square cross-section inner firebox which provides the main advantages of this design i.e. it has a greater surface area at the top of the firebox where the heat is greatest, improving heat transfer and steam production, compared with a round-top shape. The flat firebox top would make supporting it against pressure more difficult (e.g. by means of girders, or stays) compared to a round-top. However, the use of a similarly shaped square outer boiler shell allows simpler perpendicular stays to be used between the shells. The Belpaire outer firebox is, nevertheless, more complicated and expensive to manufacture than a round-top version. Due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firebox (steam Engine)
In a steam engine, the firebox is the area where the fuel is burned, producing heat to boil the water in the boiler. Most are somewhat box-shaped, hence the name. The hot gases generated in the firebox are pulled through a rack of tubes running through the boiler. Steam locomotive fire tube firebox In the standard steam locomotive fire-tube boiler, the firebox is surrounded by water space on five sides. The bottom of the firebox is open to atmospheric pressure, but covered by fire grates (solid fuel) or a firing pan (liquid fuel). If the engine burns solid fuel, like wood or coal, there is a grate covering most of the bottom of the firebox to hold the fire. An ashpan, mounted underneath the firebox and below the grates, catches and collects hot embers, ashes, and other solid combustion waste as it falls through the grates. In a coal-burning locomotive, the grates may be shaken to clean dead ash from the bottom of the fire. They are shaken either manually or (in larger locomotiv ...
