The Baldwin S-8 was an 800-horsepower (600 kW) diesel-electric locomotive intended for use in yard switching. The Baldwin Locomotive Works produced a total of 63 units (61 for United States railroads and 2 for use in Cuba) between 1951 and 1953. Of these, nine were"calf" units built for Oliver Iron Mining Company in Minnesota. A tenth calf had been built for them on a verbal order, but when delivery was refused, it was fitted with a cab, and converted to a regular S-8.
