| 1260: The Rm class is a rather rare species of the Rc-family, six units were built only. The locomotives were 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. |
