SJ Rm
The SJ Class Rm is an electric locomotive operated by Swedish State Railways ( sv, Statens Järnvägar, SJ) and later Green Cargo. The six locomotives are variants of the Rc locomotive and built by ASEA in 1977. The difference is smaller wheels giving higher pulling force, but lower maximum speed. They were used in triple-unit configuration on Malmbanan as supplements to Dm3-units, but later moved to other parts of the Swedish rail network after the transport needs on Malmbanan were reduced. When originally used to haul iron ore they were ballasted, fitted with SA3 couplings and additional set of brakes, but all these modifications were removed when the locomotives were put in ordinary freight operation. In the 1990s they were repainted from orange to blue. When SJ was split up, they were transferred to Green Cargo, stationed in Malmö. In 2013–2014 they were used again for iron ore traffic on Malmbanan. They went between Svappavaara and Narvik for Northland Resources Northl ...

ASEA
''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 tran ...

Rail Transport In Sweden
Rail transport in Sweden uses a network of 15006.25 km of track, the 22nd largest in the world. Construction of the first railway line in Sweden began in 1855. The major operator of passenger trains has traditionally been the state-owned SJ AB, though today around 70% of all rail traffic consists of subsidised local and regional trains for which the regional public transport authorities bear responsibility.Transportstyrelsen Resandeflöden på Sveriges järnvägsnät Analys av utbud och efterfrågan på tågresor (in Swedish TSJ 2019-2258.

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 ...

Green Cargo Locomotives
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, whi ...

Electric Locomotives Of Sweden
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of posit ...

Northland Resources
Northland Resources S.A. also known as Northland is a publicly traded exploration and development mining company. It currently focuses on iron ore bearing properties located in the northern regions of Sweden and Finland.

SA3 Coupler
SA3 couplers (also known as СА3 or СА-3 couplers per the typical foundry stamp on top of these couplers, meaning "Советская Автосцепка, 3" in Russian or "Soviet Auto-latch 3" in English) or Willison coupler and Russian coupler are railway couplings used primarily in Russia and states influenced or not influenced by the former Soviet Union, such as Finland, Iran, Poland and Mongolia. Russian railways originally used buffers and chain couplers during Imperial era, however these had several disadvantages: their draft load was limited, they were susceptible to buffer lock, and they were not semiautomatic like the North American Janney couplers. Conversion to Janney couplers (as Japan and Australia had) was considered, as was development of a new design. The Willison coupler was patented in 1916 by John Willison from Derby, England. The Knorr-Bremse company bought it and it started to be used in Germany for some heavy trains and some suburban trains in ...

SJ Dm3
Dm and Dm3 is a series of locomotives used by Swedish State Railways ( sv, Statens Järnvägar, SJ) and later Malmtafik i Kiruna (MTAS) for pulling iron ore trains on the Iron Ore Line in Sweden and Ofoten Line in Norway. A total of 39 double-locomotives (Dm) were delivered between 1954 and 1971, built by ASEA. A further 19 center locomotives (Dm3) were later delivered. Norwegian State Railways also operated 12 similar locomotives, designated NSB El 12. The Dm is a articulated, freight-optimized version of the Da-locomotive. History The iron ore trains on the Iron Ore Line between Luleå in Sweden and Narvik ( se, Áhkanjárga) is the third-largest municipality in Nordland county, Norway, by population. The administrative centre of the municipality is the town of Narvik. Some of the notable villages in the municipality include Ankenesstranda, Ba ... in Norway were originally operated by the Of class locomotives, based on the earlier O-series locomotives first used ...

Malmbanan
The Iron Ore Line ( sv, Malmbanan) is a long railway line between Riksgränsen and Boden in Norrbotten County, Sweden, owned by Trafikverket (the Swedish Transport Administration). The line also contains two branches, from Kiruna to Svappavaara and from Gällivare to Koskullskulle. The term is often colloquially used to also include the Ofoten Line, from Riksgränsen to Narvik in Norway, and the northernmost part of the Main Line Through Upper Norrland from Boden to Luleå. The railway from Narvik to Luleå is long. The line is dominated by the ore freight trains operated by LKAB's subsidiary Malmtrafik from their mines to the Port of Narvik and the Port of Luleå. In addition, SJ operates passenger trains and CargoNet operates container freight trains. The Iron Ore Line is single track, electrified at and has a permitted axle load of . The Swedish part of the line is the northernmost railway in Sweden and the Norwegian part outside Narvik is the northernmost r ...
