GCR Class 8H
The Great Central Railway Class 8H (LNER Class S1) was a class of 0-8-4T steam tank locomotives designed by John G. Robinson for hump shunting at Wath marshalling yard. Overview Four locomotives were built in 1907/1908 for the Great Central Railway. They were fitted with three cylinders. This gave a more even torque than with a 2-cylinder locomotive and reduced the risk of wheelslip under heavy load. All four passed into London and North Eastern Railway ownership at the 1923 grouping. At the time all four locomotives were allocated to Mexborough engine shed. These were powerful locomotives but even more power was required so, in 1930, one locomotive was fitted with a superheater and a booster engine and classified S1/2. Two new locomotives (with superheaters and boosters) were built by the LNER in 1932 and classified S1/3. The remaining (non-booster) locomotives were classified S1/1 and were also fitted with superheaters. All the boosters were removed in 1943. All six ...

Dunford Bridge Railway Station
Dunford Bridge railway station was a railway station that served the village of Dunford Bridge on the Sheffield, Ashton-under-Lyne and Manchester Railway situated immediately east of the Woodhead Tunnel, west of Penistone, within the Metropolitan Borough of Barnsley, South Yorkshire, England. The station was east of Manchester London Road (now Manchester Picadilly) and west of the now closed Sheffield Victoria station. History When the line over Woodhead was opened in 1845 the tunnels were incomplete and a stagecoach service operated from here over the hills to the station at . Because the turning space at was inadequate the stagecoach links in the Huddersfield direction via Holmfirth were also operated from here. The station was opened on 14 July 1845 and consisted of two flanking platforms, the main, stone built structure, with booking office and staff accommodation was on the Manchester-bound (Down) platform, whilst the Sheffield-bound platform (Up) had a large water t ...

Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . In ... [...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 1907
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] |

Booster Engine
A booster engine for steam locomotives is a small two-cylinder steam engine back-gear-connected to the trailing truck axle on the locomotive or the lead truck on the tender. A rocking idler gear permits it to be put into operation by the driver (engineer). It drives one axle only and can be non-reversible, with one idler gear, or reversible, with two idler gears. A booster engine is used to start a heavy train or maintain low speed under demanding conditions. Rated at about at speeds of from , it can be cut in while moving at speeds under and is semi-automatically cut out via the engineer notching back the reverse gear between , depending on the model and design of the booster. A tractive effort of is common, although ratings of up to around were possible. Tender boosters are equipped with side-rods connecting axles on the lead truck. Such small side-rods restrict speed and are therefore confined to switching locomotives, often used in transfer services between yards. Tende ...

Superheater
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres). Types * A radiant superheater is placed directly in radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. * A convection superheater is located in the convective zone of the furnace usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters. * A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system. This superheater design incorporates additional burners in the area of superheater pipes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mexborough Engine Shed
Mexborough engine shed was an engine shed in Swinton, in South Yorkshire, England. It was built by the Great Central Railway and opened in 1875. The shed was built slightly to the west of the current Mexborough station on land between the River Don and the River Don Navigation. It had 15 dead end roads, and could handle about 150 steam locomotives, mainly for use on freight trains. The London and North Eastern Railway operated the shed from 1923. In 1948, on the formation of British Railways Eastern Region, Mexborough bore the shed code 36B, then 41F from 1958. It closed in February 1964. Most of the locomotives stabled at Mexborough were used for hauling coal trains. The coal originated from the many collieries in the South Yorkshire coalfield and wagons of coal were despatched to locations all over the country. However, the main destinations were the industries and power stations in Lancashire. With the opening of the Wath marshalling yard in 1907, Mexborough supplied l ...

Railways Act 1921
The Railways Act 1921 (c. 55), also known as the Grouping Act, was an Act of Parliament enacted by the British government and intended to stem the losses being made by many of the country's 120 railway companies, by "grouping" them into four large companies dubbed the " Big Four". This was intended to move the railways away from internal competition, and retain some of the benefits which the country had derived from a government-controlled railway during and after the Great War of 1914–1918. The provisions of the Act took effect from the start of 1923. History The British railway system had been built up by more than a hundred railway companies, large and small, and often, particularly locally, in competition with each other. The parallel railways of the East Midlands and the rivalry between the South Eastern Railway and the London, Brighton and South Coast Railway at Hastings were two examples of such local competition. During the First World War the railways were under st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Factor Of Adhesion
An adhesion railway relies on adhesion traction to move the train. Adhesion traction is the friction between the drive wheels and the steel rail. The term "adhesion railway" is used only when it is necessary to distinguish adhesion railways from railways moved by other means, such as by a stationary engine pulling on a cable attached to the cars or by railways that are moved by a pinion meshing with a rack. The friction between the wheels and rails occurs in the wheel-rail interface or contact patch. The traction force, the braking forces and the centering forces, all contribute to stable running. However, running friction increases costs by requiring higher fuel consumption and by increasing the maintenance needed to address fatigue (material) damage, wear on rail heads and on the wheel rims and rail movement from traction and braking forces. Variation of friction coefficient Traction or friction is reduced when the top of the rail is wet or frosty or contaminated with greas ...
