Rm is a electric locomotive operated by Statens Järnvägar 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. Originally also extra weight added, SA3 coupelings and another set of brakes according to iron ore train needs. 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. They were rebuilt with standard couplers. In the 1990s they were repainted from brown to blue. When SJ was split up, they were transferred to Green Cargo. All still remain in service, stationed in Malmö.
