Little History:

The GM10B was a solitary electric testbed locomotive with a power output of 10,000 hp (7.46 MW) which was intended for use on high-speed freight services on the Northeast Corridor. Built by American locomotive builder Electro-Motive Division (EMD) at its La Grange, Illinois, plant in collaboration with ASEA of Sweden. It entered service with Penn Central in August 1976 and featured a B-B-B wheel arrangement, a first for the North American market, while having a high proportion of Swedish built components and design features created by ASEA.
