Shunter
A switcher locomotive (American English), shunter locomotive (British English), station pilot (British English), or shifter locomotive ( Pennsylvania Railroad terminology) is a locomotive used for maneuvering railway vehicles over short distances. Switchers do not usually move trains over long distances. Instead, they typically assemble trains in order for another locomotive to take over. Switchers often operate in a railyard or make short transfer runs. They may serve as the primary motive power on short branch lines or switching and terminal railroads. A hybrid type known as a road switcher can both shunt and haul trains. Switchers are optimized for their role, being relatively low-powered but with a high starting tractive effort for getting heavy cars rolling quickly. Switchers are geared to produce high torque but are restricted to low top speeds and have small diameter driving wheels. Switchers tend to be durable and to remain in service for a long time, such as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SJ U
U is a class of 152 electric shunter locomotives operated by the Swedish State Railways () 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). The locomotives worked well, ...

Diesel–electric Locomotive
A diesel locomotive is a type of railway locomotive in which the power source 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. The most common are diesel–electric locomotives and diesel–hydraulic. 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 leve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 (electricity), battery or a supercapacitor. Locomotives with on-board fuelled prime mover (locomotive), prime movers, such as diesel engines or gas turbines, are classed as Diesel–electric powertrain, diesel–electric or turbine–electric powertrain, gas turbine–electric and not as electric locomotives, because the electric generator/motor combination serves only as a Transmission (mechanics), 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 loco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Switcher
A road switcher locomotive is a type of railroad locomotive designed to both haul railroad car, railcars in mainline service and Shunting (rail), shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere. A road switcher must be able to operate and have good visibility in both directions. As a road engine, a road switcher must be able to operate at road speeds, with suitable power and cooling capacity. It has high-speed road trucks rather than low-speed switcher only trucks. Modern road trucks are always equipped with "frictionless" roller bearings, whereas switcher trucks were almost always equipped with "friction" plain bearings, until plain bearings were outlawed in interchange service on both railcars and locomotives. Overview For the reasons given above, road switchers are generally hood units. The set-back cab of a hood unit provides more safety in the event of a collision at speed than most switche ...

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 then 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. It exceeded expectations, and 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 has been built to house more of the national collection. In addition, parts of th ...

North Eastern Railway (UK)
The North Eastern Railway (NER) was an England, English rail transport, 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 Railways Act 1921, 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, England, 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 (Great Britain), Great Northern Railwa ...

Railyard
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 switcher locomotives (US) or shunter locomotives (UK), 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 a ...

Driving Wheel
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. On diesel and electric locomotives, the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft drive and coupling rods were used in the past (e.g. in the Swiss Crocodile locomotive) but their use is now confined to shunter locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets with wheels within each set linked together. Diameter Drivin ...

Slug (railroad)
In railroading, a slug is a version of a diesel–electric locomotive which lacks a Prime mover (locomotive), prime mover and often a cab. It derives the electrical power needed to operate its traction motors and motor controls from a fully-powered mother locomotive. At low speeds the drawing (or regenerative braking, braking) force a diesel–electric locomotive can produce is often limited by its traction motors or the grip of its drive wheels on the track, not the capability of its diesel engine(s). A slug adds more traction motors and drive wheels to both use more of the power the mother's engine can produce that cannot otherwise be used at low speeds and provide better braking, without the expense of a full locomotive. A slug is distinct from a B unit, which has both a prime mover and traction motors but no cab. A slug may have an operator's cab to allow engineers to operate a train with the slug in the lead, or the cab and much of the body can be omitted to reduce cost an ...

Cow–calf
In rail transport, a cow–calf (also cow and calf, or in the master and slave) is a set of diesel switcher locomotives. The set is usually a pair, though a few three-unit sets (with two calves, also known as ''herds'') were built. A cow is equipped with a cab, and a calf is not. The two are coupled together (either with regular couplers or a semi-permanent drawbar) and equipped with multiple unit train control so that both locomotives can be operated from the single cab. A cow is analogous to an ''A unit'', i.e. a locomotive with a cab, and a calf to a '' B unit'', i.e. a powered, cabless road locomotive. That is, the cow and calf are each equipped with at least one prime mover for propulsion. A cow–calf set is distinct from a ''slug-and-mother'' set in that a cow and a calf are each independently powered while a ''slug'' has no prime mover and instead is dependent on power from its ''mother'' unit. Like the early EMD FT locomotives, cow–calf sets were typically b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
