The BLH S8 was an 875hp diesel–electric switcher locomotive. The Baldwin-Lima-Hamilton Corporation 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 order, but when delivery was refused, it was fitted with a cab, and converted to a regular S8.[1]
