The Swedish Rc4 locomotives were tested on the Northeast Corridor with success and NSB also chose to try the units on Bergensbanen. The locomotives were also equipped with dynamic slip control. In 1976 NSB ordered six unites, but chose to modify the Rc4 design, including the pointed nose which is able to force through the occasional snowdrifts. In 1980 another four units were delivered and the final seven in 1984. The sets were numbered 16?2201 to 16?2217.

But the systems have since been upgraded.
