The SJ Class Rm is an electric locomotive operated by Swedish State Railways (Swedish: Statens Järnvägar, SJ) and later Green Cargo.

The difference is smaller wheels giving higher pulling force, but lower maximum speed.

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.

When SJ was split up, they were transferred to Green Cargo, stationed in Malmö.

After the Northland bankruptcy they were parked but returned to service in 2016 (with standard couplings).The locomotives are now used by Green cargo and hauling various freight trains all around Sweden
