NSB El 12 was an electric locomotive used by the Norwegian State Railways (NSB) to haul iron ore trains on Ofoten Line between 1957 and 1990. The locomotives were based on the Swedish Dm that was used with success on the connecting Iron Ore Line. The eight units were always operated in pairs or in triples and were numbered 12 2113 - 12 2120. Four double sets remain as heritage locomotives.

After World War II the production resumed at the mines operated by LKAB at Kiruna and Malmberget with estimates of a 50% production increase within few years. To solve the problems with increased traffic, the railway companies had the choice of either building double track or hauling longer trains. The latter solution was chosen, and on the Norwegian side the ten El 3 locomotives were converted from five double sets to three triple sets with one reserve and the two El 4 converted to a double set. But this solution would require more locomotives.

The Swedish State Railways (SJ), who operated the trains from the mines to Riksgränsen, chose to buy 12 Dm units in 1952, based on the Da units from 1950. NSB chose to buy six more or less identical units from Motala Verkstad in 1954 and an additional two in 1957 from NOHAB. But the ore production continued to increase, and in 1960 SJ ordered a middle section for their Dm units, creating the Dm+Dm3+Dm unit configuration. NSB chose to rebuild three of their locomotive pairs to triple units, but in 1967 NSB ordered six new technically far more advanced El 15 locomotives. The El 12 units were taken out of service between 1989 and 1992.

NSB El 18 is a class of 22 electric locomotives built by Adtranz and Swiss Locomotive and Machine Works (SLM) for the Norwegian State Railways (NSB). The class is a modification of the Swiss Federal Railways Re 460 locomotive and built at Adtranz Strømmen in 1996 and 1997. The class remains the only mainline electric locomotive used by NSB, and is predominantly used on some intercity services and all night trains on the Bergen Line, Dovre Line and Sørland Line, as well as some regional trains.

NSB El 17 locomotive class

The NSB El 17 is a class of twelve electric locomotives built by Thyssen-Henschel and Norsk Elektrisk & Brown Boveri (NEBB) for the Norwegian State Railways (NSB). The class was built in two batches, the first delivered in 1982 and numbered 2221–2226, and the second delivered in 1987 and numbered 2227–2232. The traction system of the El 17 was based on the DB Class 120 of Germany and were among the first in the world to feature three-phase asynchronous motors. The units were ordered to be used on the intercity Bergen, Dovre and Sørland Lines, but were plagued with technical faults. The unreliability and lack of sufficient power forced NSB to instead use them in the regional Vestfold and Gjøvik Lines. With the delivery of the El 18, the first series was retired or used as shunters. The second series has been used on the Flåm Line since 1998.

Iore, often stylized IORE, is a class of 34 electric locomotives built by Adtranz and its successor Bombardier Transportation for the Swedish mining company LKAB's railway division Malmtrafik. The class is a variation of Adtranz's Octeon modular product platform, thus related to Bombardier's later TRAXX platform. The locomotives haul iron ore freight trains on the Iron Ore Line and Ofoten Line in Sweden and Norway, respectively. The 8,600-tonne 68-car trains are hauled by two single-ended Co′Co′ locomotives, each with a power output of 5,400 kW (7,200 hp). Each operates with 600 kilonewtons tractive effort and has a maximum speed of 80 km/h (50 mph). Delivery of the first series of 18 locomotives was made from 2000 to 2004, and they replaced some of the aging Dm3 and El 15 units. In 2007, eight more vehicles were ordered, with production to be completed by 2011, by which time, another four double units were ordered. These units are scheduled to be delivered from 2013 to 2014.

Dm and Dm3 is a series of locomotives used by Swedish State Railways 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.

SJ Rm locomotive class

The SJ Class Rm is an electric locomotive operated by Swedish State Railways 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, using SA3 couplings. After the Northland bankruptcy they were parked but returned to service in 2016.
