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 ...

Electrification
Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source. The broad meaning of the term, such as in the history of technology, economic history, and economic development, usually applies to a region or national economy. Broadly speaking, electrification was the build-out of the electricity generation and electric power distribution systems that occurred in Britain, the United States, and other now- developed countries from the mid-1880s until around 1950 and is still in progress in rural areas in some developing countries. This included the transition in manufacturing from line shaft and belt drive using steam engines and water power to electric motors. The electrification of particular sectors of the economy is called by terms such as ''factory electrification'', ''household electrification'', ''rural electrification'', ''aviation electrification'' or ''railway electrificati ...

Southern Railway (Great Britain)
The Southern Railway (SR), sometimes shortened to 'Southern', was a British railway company established in the 1923 Grouping. It linked London with the Channel ports, South West England, South coast resorts and Kent. The railway was formed by the amalgamation of several smaller railway companies, the largest of which were the London and South Western Railway (LSWR), the London, Brighton and South Coast Railway (LB&SCR) and the South Eastern and Chatham Railway (SE&CR).Bonavia (1987) pp. 26-28 The construction of what was to become the Southern Railway began in 1838 with the opening of the London and Southampton Railway, which was renamed the London & South Western Railway. The railway was noted for its astute use of public relations and a coherent management structure headed by Sir Herbert Walker. At , the Southern Railway was the smallest of the '' Big Four'' railway companies and, unlike the others, the majority of its revenue came from passenger traffic rather than freight. ...

Big Four British Railway Companies
"Big Four" was a name used to describe the four largest railway companies in the United Kingdom in the period 1923–1947. The name was coined by ''The Railway Magazine'' in its issue of February 1923: "The Big Four of the New Railway Era". The Big Four were: * Great Western Railway (GWR) * London, Midland and Scottish Railway (LMS) * London and North Eastern Railway (LNER) * Southern Railway (SR) The companies were formed as a result of the Railways Act 1921, in a process known as "The Grouping" (of the railways), which came into effect on 1 January 1923. On 1 January 1948 the companies were nationalised to form British Railways as a result of the Transport Act 1947. Characterisation The three larger companies relied heavily on freight (especially coal), as well as long-distance passenger traffic. The Southern Railway, in contrast, was predominantly a passenger railway, which, despite its small size, carried more than a quarter of the total UK passenger traffic. That ...

New York Central Railroad
The New York Central Railroad was a railroad primarily operating in the Great Lakes and Mid-Atlantic regions of the United States. The railroad primarily connected greater New York and Boston in the east with Chicago and St. Louis in the Midwest, along with the intermediate cities of Albany, Buffalo, Cleveland, Cincinnati, Detroit, Rochester and Syracuse. New York Central was headquartered in New York City's New York Central Building, adjacent to its largest station, Grand Central Terminal. The railroad was established in 1853, consolidating several existing railroad companies. In 1968, the NYC merged with its former rival, the Pennsylvania Railroad, to form Penn Central. Penn Central went bankrupt in 1970 and merged into Conrail in 1976. Conrail was broken-up in 1999, and portions of its system were transferred to CSX and Norfolk Southern Railway, with CSX acquiring most of the old New York Central trackage. Extensive trackage existed in the states of New York, Pennsyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Railroad
The Pennsylvania Railroad (reporting mark PRR), legal name The Pennsylvania Railroad Company also known as the "Pennsy", was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. It was named for the commonwealth in which it was established. By 1882, Pennsylvania Railroad had become the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Its budget was second only to the U.S. government. Over the years, it acquired, merged with, or owned part of at least 800 other rail lines and companies. At the end of 1926, it operated of rail line;This mileage includes companies independently operated. PRR miles of all tracks, which includes first (or main), second, third, fourth, and sidings, totalled 28,040.49 at the end of 1926. in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific and Atchison, T ...

Water Trough
A water trough (British terminology), or track pan (American terminology) is a device to enable a steam locomotive to replenish its water supply while in motion. It consists of a long trough filled with water, lying between the rails. When a steam locomotive passes over the trough, a water scoop can be lowered, and the speed of forward motion forces water into the scoop, up the scoop pipe and into the tanks or locomotive tender. Origin Steam locomotives consume a considerable amount of water, and the tender or side tanks need to be replenished at intervals. Traditionally the engine water was replenished during station stops, but if it was desired to run long distances without stopping, the requirement to take water was a significant limitation. ''The Railway Magazine'' reported a development by John Ramsbottom: Ramsbottom arranged some experiments and showed that the forward motion of a scoop in a trough of water would force water up a connected pipe and into a tank. He calc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbopump
A turbopump is a propellant pump with two main components: a rotodynamic pump and a driving gas turbine, usually both mounted on the same shaft, or sometimes geared together. They were initially developed in Germany in the early 1940s. The purpose of a turbopump is to produce a high-pressure fluid for feeding a combustion chamber or other use. There are two types of turbopumps: a centrifugal pump, where the pumping is done by throwing fluid outward at high speed, or an axial-flow pump, where alternating rotating and static blades progressively raise the pressure of a fluid. Axial-flow pumps have small diameters but give relatively modest pressure increases. Although multiple compression stages are needed, axial flow pumps work well with low-density fluids. Centrifugal pumps are far more powerful for high-density fluids but require large diameters for low-density fluids. History Early development High-pressure pumps for larger missiles had been discussed by rocket pioneers su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Injector
An injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid in such a way that a lower pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts except a valve to control inlet flow. A steam injector is a typical application of the principle used to deliver cold water to a boiler against its own pressure, using its own live or exhaust steam, replacing any mechanical pump. When first developed, its operation was intriguing because it seemed paradoxical, almost like perpetual motion, but it was later explained using thermodynamics. Other types of injector may use other pressurised motive fluids such as air. Depending on the application, an injector can also take the form of an ''eductor-jet pump'', a ''water eductor'' or an ''aspirator''. An '' ejector'' operates on similar principles to create a vacuum feed connection for braking systems etc. History The ... [...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 ...
