Electric motor class Rm 1260 of the Green Cargo. Total 6 locos class Rm were built for the ore service Kiruna-Narvik. Therefor the Rc-loco design was modified: additional weight, lower top speed, higher tractive force and special equipment (brake, coupler) for ore service. Our Rm model features a slower running motor and higher gear reduction to copy the prototypes special features. Rm locos operated for a long time period in Southern Sweden in regular GC freight service. Today Rm locos are painted green and returned to the ore service for Green Cargo.
