SJ Ra
The SJ Class Ra (or Rapid) is an electric locomotive operated by Swedish State Railways ( sv, Statens Järnvägar, SJ). Ten units were built by ASEA, two in 1955 and eight in 1961. Ra was used on express trains until the 1990s. History During the 1940s SJ had a need for quicker locomotives for their express trains. In 1953 two bogie-locomotives were ordered from ASEA. Inspiration for the appearance came from North America, with round shapes and a bulldog nose. The two first units were successful and SJ ordered additional eight units from ASEA, delivered in 1961. Though never being used for more than 130 km/h, it was capable for 150 km/h, and served mainly on Stockholm - Göteborg and Stockholm - Oslo. They were mainly taken out of service in the late 1980s, though two remained in service until 1996. Most have been preserved, including at the Swedish Railway Museum The Swedish Railway Museum, ( sv, Sveriges Järnvägsmuseum), in Gävle, Gästrikland, Sweden is the nati ...

Swedish Railway Museum
The Swedish Railway Museum, ( sv, Sveriges Järnvägsmuseum), in Gävle, Gästrikland, Sweden is the national museum for Sweden's railway history. The Swedish Railway Museum is tasked with acquiring, preserving and supplying knowledge about Swedish railway history on the basis of the national collection. The museum is owned by Trafikverket (Swedish Transport Administration), which receives an annual sum for the museum's activities from the Government. History In 1915, the National Railway Board opened a railway museum in Stockholm. In 1942, a hall for locomotives and rolling stock was added at Tomteboda railway station in Stockholm. The Swedish Railway Museum has been located in Gävle since 1970. The Museum has the use of two yards with tracks and several large buildings, including two round loco sheds and a sizeable workshop. The complex covers a total area of some 16,000 square metres. Collections Some items for the collection had already been acquired by the end of the 19th ...

Bulldog Nose
"Bulldog nose" is the nickname given, due to their appearance, to several diesel locomotives manufactured by GM-EMD and its licensees from 1939 to 1970. The term originated with EMD F-units, as well as later E-unit models such as the E7, E8, and E9. The bulldog nose design has been described as " iconic". It was a blunter and more vertical variation of the similar "slant nose" style, which featured a more sloped front and often less protruding headlight. Examples of this included the EMC E1. Clyde Engineering derivatives In 1951, the EMD F7 series was modified by General Motors' Australian licence holder Clyde Engineering to fit Australian loading gauge and axle load constraints. The A1A-A1A Clyde/EMD ML1 locomotive was introduced on the Commonwealth Railways as the GM class, as well as exported to Pakistan. It was further developed into the ML2 as a dual cab Co-Co locomotive, with a bulldog nose at each end, for Victorian Railways (VR), becoming that system's B class.Obe ...

Bo′Bo′ Locomotives
B-B and Bo-Bo are the Association of American Railroads (AAR) and British classifications of wheel arrangement for railway locomotives with four axles in two individual bogies. They are equivalent to the B′B′ and Bo′Bo′ classifications in the UIC system. The arrangement of two, two-axled, bogies is a common wheel arrangement for modern electric and diesel locomotives. Bo-Bo Bo-Bo is the UIC indication of a wheel arrangement for railway vehicles with four axles in two individual bogies, all driven by their own traction motors. It is a common wheel arrangement for modern electric and diesel-electric locomotives, as well as power cars in electric multiple units. Most early electric locomotives shared commonalities with the steam engines of their time. These features included side rods and frame mounted driving axles with leading and trailing axles. The long rigid wheelbase and the leading and trailing axles reduced cornering stability and increased weight. The Bo-Bo co ...

ASEA Locomotives
''Allmänna Svenska Elektriska Aktiebolaget'' (English translation: General Swedish Electrical Limited Company; Swedish abbreviation: ASEA) was a Swedish industrial company. History ASEA was founded in 1883 by Ludvig Fredholm in Västerås as a manufacturer of electrical light and generators. After merging with Wenström's & Granström's Electrical Power Company (''Wenströms & Granströms Elektriska Kraftbolag'') the name was changed to ''Allmänna Svenska Elektriska Aktiebolaget'', literally the "General Swedish Electrical Limited Company", or a ''ASEA'' for short. In 1987, it announced a merger with the Swiss company Brown, Boveri & Cie (BBC) to form ABB Group. ABB Group began operations in 1988. After this merger, ABB Group acquired several companies, including the power transmission and distribution operations of the Westinghouse Electric Corporation and the Combustion Engineering Group. *1889 - the partner Jonas Wenström creates 3-phased generators, motors and transfor ...

Railway Locomotives Introduced In 1955
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 facilit ...

Nässjö Railway Museum
Nässjö () is a locality and the seat of Nässjö Municipality, Jönköping County, Sweden with 16,678 inhabitants in 2010. History For many years, Nässjö was a rural village with agriculture as the dominant occupation. The turning point was the construction of the Swedish railway system. The southern main line railway, finished in 1864, passed through Nässjö. Later, other railways were inaugurated, whereby Nässjö, due to its geographical location in the country, became an important junction. A line to Katrineholm was opened in 1874, and that year also the opening of the Oskarshamn line; the one to Halmstad in 1882; to Kalmar in 1914. Today, Nässjö is the only Swedish junction where railways in six different directions meet. As a result, industries moved to Nässjö, and the population increased. The most important industries were wood industries due to the forest covered Småland province area, at a time when it had become possible to factory manufacture the woo ...

Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. ...

Swedish State Railways
The Swedish State Railways ( sv, Statens Järnvägar) or SJ, originally the Royal Railway Board ( sv, Kungl. Järnvägsstyrelsen), was the former government agency responsible for operating the state-owned railways in Sweden. It was created in 1887 as an agency belonging to the Ministry for Civil Service Affairs, with the task of managing all state-owned railway lines in Sweden, and was transferred to the Ministry of Communications in 1920. In 1988, the rail tracks themselves were transferred to the Swedish Rail Administration ( sv, Banverket), and in the upcoming years parts of SJ were gradually transformed into limited companies as a result of the open access obligation introduced by EU Directive 91/440. SJ was disbanded in 2001, with the assets transferred to seven separate companies, the first three owned by the Swedish government and the latter four being privatized: *SJ AB, usually called SJ, the passenger train operator *Green Cargo, which operates freight trains *Jer ...

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 ...
