Shunter
A switcher, shunter, yard pilot, switch engine, yard goat, or shifter is a small railroad locomotive used for manoeuvring railroad cars inside a rail yard in a process known as ''switching'' (US) or ''shunting'' (UK). Switchers are not intended for moving trains over long distances but rather for assembling trains in order for another locomotive to take over. They do this in classification yards (Great Britain: ''marshalling yards''). Switchers may also make short transfer runs and even be the only motive power on branch lines and switching and terminal railroads. The term can also be used to describe the workers operating these engines or engaged in directing shunting operations. Switching locomotives may be purpose-built engines, but may also be downgraded main-line engines, or simply main-line engines assigned to switching. Switchers can also be used on short excursion train rides. The typical switcher is optimised for its job, being relatively low-powered but with a high ...

Shunt (railway Operations)
Shunting, in railway operations, is the process of sorting items of rolling stock into complete trains, or the reverse. In the United States this activity is known as switching. Motive power Motive power is normally provided by a locomotive known as a ''shunter'' (in the UK) or switcher (in the US). Most shunter/switchers are now diesel-powered but steam and even electric locomotives have been used. Where locomotives could not be used (e.g. because of weight restrictions) shunting operations have in the past been effected by horses or capstans. Hazards Coupling The terms "shunter" and "switcher" are applied not only to locomotives but to employees engaged on the ground with shunting/switching operations. The task of such personnel is particularly dangerous because not only is there the risk of being run over, but on some railway systems—particularly ones that use buffer-and-chain/screw coupling systems—the shunters have to get between the wagons/carriages in order to ...

SJ U
U is a class of 152 electric shunter locomotives operated by the Swedish State Railways ( sv, Statens Järnvägar, SJ) and Trafikaktiebolaget Grängesberg–Oxelösunds Järnvägar (TGOJ) of Sweden, and the Norwegian State Railways (NSB), LKAB and Norsk Jernverk of Norway. They were built by ASEA, Nyqvist och Holm, Motala, ASJ Falun and Thune between 1926 and 1956. NSB gave the class the designation El 10. History Swedish State Railways During the 1920s the Swedish State Railways started a program to electrify parts of their network. This caused a need for electric shunters on the West Main Line. A procurement was attempted from Switzerland, but no order was ever made. With the order of the D Class locomotives, SJ decided to order a shunter built with the same components. The initial order was for three Ua-locomotives to be built in 1926 with delivery the following year. The motors were built by ASEA while the mechanical components were built by Nydqvist och Holm (NOHAB). T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too qu ...

Coupling Rods
A coupling rod or side rod connects the driving wheels of a locomotive. Steam locomotives in particular usually have them, but some diesel and electric locomotives, especially older ones and shunters, also have them. The coupling rods transfer the power of drive to all wheels. Development Locomotion No. 1 was the first locomotive to employ coupling rods rather than chains. In the 1930s reliable roller bearing coupling rods were developed. Allowance for vertical motion In general, all railroad vehicles have spring suspension; without springs, irregularities in the track could lift wheels off the rail and cause impact damage to both rails and vehicles. Driving wheels are typically mounted so that they have around 1 inch (2.5 cm) of vertical motion. When there are only 2 coupled axles, this range of motion places only slight stress on the crank pins. With more axles, however, provision must be made to allow each axle to move vertically independently of the others without ...

Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack o ...

Rail Yard
A rail yard, railway yard, railroad yard (US) or simply yard, is a series of tracks in a rail network for storing, sorting, or loading and unloading rail vehicles and locomotives. Yards have many tracks in parallel for keeping rolling stock or unused locomotives stored off the main line, so that they do not obstruct the flow of traffic. Cars or wagons are moved around by specially designed yard switchers (US) or shunters, a type of locomotive. Cars or wagons in a yard may be sorted by numerous categories, including railway company, loaded or unloaded, destination, car type, or whether they need repairs. Yards are normally built where there is a need to store rail vehicles while they are not being loaded or unloaded, or are waiting to be assembled into trains. Large yards may have a tower to control operations. Many yards are located at strategic points on a main line. Main-line yards are often composed of an up yard and a down yard, linked to the associated direction of trave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail Transport
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Eastern Railway (UK)
The North Eastern Railway (NER) was an English railway company. It was incorporated in 1854 by the combination of several existing railway companies. Later, it was amalgamated with other railways to form the London and North Eastern Railway at the Grouping in 1923. Its main line survives to the present day as part of the East Coast Main Line between London and Edinburgh. Unlike many other pre-Grouping companies the NER had a relatively compact territory, in which it had a near monopoly. That district extended through Yorkshire, County Durham and Northumberland, with outposts in Westmorland and Cumberland. The only company penetrating its territory was the Hull & Barnsley, which it absorbed shortly before the main grouping. The NER's main line formed the middle link on the Anglo-Scottish "East Coast Main Line" between London and Edinburgh, joining the Great Northern Railway near Doncaster and the North British Railway at Berwick-upon-Tweed. Although primarily a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Shields
South Shields () is a coastal town in South Tyneside, Tyne and Wear, England. It is on the south bank of the mouth of the River Tyne. Historically, it was known in Roman times as Arbeia, and as Caer Urfa by Early Middle Ages. According to the 2011 census, the town had a population of 75,337. It is the fourth largest settlement in Tyne and Wear; after Newcastle upon Tyne, Sunderland and Gateshead. The town became part of Tyne and Wear in 1974. It is within the historic county boundaries of County Durham. History The first evidence of a settlement within what is now the town of South Shields dates from pre-historic times. Stone Age arrow heads and an Iron Age round house have been discovered on the site of Arbeia Roman Fort. The Roman garrison built a fort here around AD 160 and expanded it around AD 208 to help supply their soldiers along Hadrian's Wall as they campaigned north beyond the Antonine Wall. Divisions living at the fort included Tigris bargemen (from Persia and m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shildon
Shildon is a town and civil parish in County Durham, in England. The population taken at the 2011 Census was 9,976. The town has the Locomotion Museum, due to it having the first , built in 1825, and locomotive works on the Stockton and Darlington Railway. History The name Shildon comes from the Old English word ''sceld'', This translates as 'shelf shaped hill' or 'shield/refuge'. Another possibility is the Old English word ''syclfe'' meaning 'shelf' and the suffix ''duri'' meaning 'hill'. This refers to the town's location on a limestone escarpment.Shildon County Durham Conservation Area Prepared for Sedgefield Borough Council Conservation Area Character Appraisal December 2008 ''Report No: 0055/1-08'' Report by Archaeo-Environment Ltd The earliest inhabitants of the area were most likely present from the Mesolithic period some 6,000 years ago.

Shildon Locomotion Museum
Locomotion, previously known as Locomotion the National Railway Museum at Shildon, is a railway museum in Shildon, County Durham, England. The museum was renamed in 2017 when it became part of the Science Museum Group. Overview The museum was opened on 22 October 2004 by Prime Minister of the United Kingdom, Prime Minister and local MP Tony Blair. Built at a cost of £11.3 million, it is based on the former "Timothy Hackworth Victorian Railway Museum". The museum is operated in partnership with Durham County Council and was expected to bring 60,000 visitors a year to the small town. However, during its first six months, the museum attracted 94,000 visits. Locomotion was shortlisted as one of the final five contenders in the Gulbenkian Prize, which is the largest arts prize in the United Kingdom. As part of the 2025 plans for the National Railway Museum, a second building will be built to house more of the wider collection. In addition, parts of the original museum including th ...
