GNR Class L1
The Great Northern Railway (GNR) Class L1 (LNER Class R1) was a 0-8-2T side tank steam locomotive designed by Henry Ivatt. It was originally designed for suburban passenger traffic on the Metropolitan City Lines. A prototype was built in 1903, but it was overweight, so it was rebuilt with a smaller boiler and shorter side tanks. Ten more engines were then built to this modified design. During the "small boiler" era, the cylinders were lined to 18" to match the boilers. In 1905 and 1906, thirty more engines were built for working goods trains in the West Riding of Yorkshire. The original eleven engines were not a great success on passenger services so, in 1907, they were moved to the West Riding for goods work. Condensing apparatus The first eleven locomotives were fitted with condensing apparatus for working in tunnels. The thirty built for the West Riding were probably not so fitted, but this is subject to confirmation. It is not known whether the condensing apparatus ...

Henry Ivatt
Henry Alfred Ivatt (16 September 1851, Wentworth, Cambridgeshire – 25 October 1923) was an English railway engineer, and was the Chief Mechanical Engineer of the Great Northern Railway from 1896 to 1911. Career London and North Western Railway Educated at Liverpool College., at age 17, Ivatt was apprenticed to John Ramsbottom at the Crewe Works of the London and North Western Railway (LNWR). He worked as a fireman for six months and held various positions there. He was made head of the Holyhead Locomotive Depot in 1874, before being promoted to the head of the Chester District. Great Southern and Western Railway In 1877, Ivatt moved to Ireland, and the Great Southern and Western Railway at Inchicore. In 1882, he was appointed to the post of locomotive engineer there, where he patented a design for a sprung flap for vertically-opening carriage windows that became ubiquitous. Great Northern Railway In 1895, Ivatt returned to England and was appointed Locomotive Super ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scrapped Locomotives
Scrap consists of recyclable materials, usually metals, left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling. Once collected, the materials are sorted into types — typically metal scrap will be crushed, shredded, and sorted using mechanical processes. Scrap recycling is important for creating a more sustainable economy or creating a circular economy, using significantly less energy and having far less environmental impact than producing metal from ore. Metal recycling, especially of structural steel, ships, used manufactured goods, such as vehicles and white goods, is a major industrial activity with complex networks of wrecking yards, sorting facilities and recycling plants. Processing Scrap metal originates both in business and residential environments. Typically a "scrapper" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Locomotives Introduced In 1903
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mekarski System
The Mekarski system was a compressed-air propulsion system for trams invented by Louis Mékarski or Louis Mékarsky (the correct spelling is uncertain) in the 1870s. He worked in France, was born in 1843 in Clermont-Ferrand (center of France) of Polish origin. Many references to him use the Polish name ''Ludwik Mękarski''. Overview A problem with compressed-air propulsion is that the air cools as it expands, which can lead to the formation of ice in the power cylinders. Mekarski sought to overcome this problem by heating the air with steam, produced in a small boiler called a ''bouillotte''. It is uncertain whether the steam was mixed with the air, or whether there was a heat exchanger. It was a single-stage engine in that air was expanded in one piston and then exhausted. The air was reheated after leaving the tank and before entering the engine. The reheater bubbled air through a hot water tank, picking up hot water vapor to improve the engine's range. An improved engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boiler (steam Generator)
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 com ...

Air Compressor
An air compressor is a pneumatic device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When the tank's pressure reaches its engineered upper limit, the air compressor shuts off. The compressed air, then, is held in the tank until called into use. The kinetic energy provided by the compressed air can be used for a variety of applications such as pneumatic tool as it is released air and the tank depressurizes. When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank. An air compressor must be differentiated from a pump because it works for any gas/air, while pumps work on a liquid. Classification Compressors may be classified according to the pressure delivered: # Low-pressure air compressors (LPACs), which have ...

Prime Mover (locomotive)
In engineering, a prime mover is an engine that converts fuel to useful work. In locomotives, the prime mover is thus the source of power for its propulsion. In an engine-generator set, the engine is the prime mover, as distinct from the generator. Definition In a diesel-mechanical locomotive, the prime mover is the diesel engine that is mechanically coupled to the driving wheels (drivers). In a diesel-electric locomotive, the prime mover is the diesel engine that rotates the main generator responsible for producing electricity to power the traction motors that are geared to the drivers. The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not part of the prime mover. A wired-electric or battery-electric locomotive has no on-board prime mover, instead relying on an external power station. Weight distribution The power unit rep ...

Doncaster Works
Doncaster Railway Works is a railway workshop located in Doncaster, England. Also referred to as The Plant''", it was established by the Great Northern Railway in 1853, replacing the previous works in Boston and Peterborough. Until 1867 it undertook only repairs and maintenance. Today the remaining part is operated by Wabtec. History In 1866, Patrick Stirling was appointed as Locomotive Superintendent, and the first of the 875 class was built in 1886. At this time the works also began building new coaches: in 1873 the first sleeping cars; in 1879 the first dining cars in the United Kingdom; and in 1882 the first corridor coaches. In 1891, 99 locomotives, 181 carriages and 1,493 wagons were built. Among the locomotives the works produced were the Stirling Singles, the Ivatt Atlantics and the Gresley Pacifics, including the world-famous '' Flying Scotsman'', the first locomotive to achieve 100 mph and also run from London King's Cross to Edinburgh Waverley non-stop; ...
