The EMD SD10 were a six-axle 1,800 hp (1,300 kW; 1.3 MW) diesel locomotive, which was a rebuild from EMD SD7 and SD9 diesel locomotives. These units were rebuilt by the Chicago, Milwaukee, St. Paul and Pacific Railroad/Milwaukee Road between March 1974 and January 1976.
History[edit]
Between March 1974 and January 1976, the Chicago, Milwaukee, St. Paul and Pacific Railroad/Milwaukee Road had undertook a rebuilding program that involved rebuilding a total of 17 SD7 units and 4 SD9 units into 21 EMD SD10 units at the Milwaukee Road's West Milwaukee shops.[3]
The Milwaukee Road rebuilt units specifically to be a six-axle variant of the four-axled GP10, which the GP10s were rebuilds of EMD GP7 and GP9 units.
The rebuild program involved replacing the original 16-cylinder 567B and 567C prime movers with more powerful 16-cylinder 645E prime movers, this changed the horsepower from 1,500 horsepower (1,100 kilowatts; 1.1 megawatts) and 1,750 horsepower (1,300 kilowatts; 1.30 megawatts) to 1,800 horsepower (1,300 kilowatts; 1.3 megawatts).[3]
When the Milwaukee Road filed for bankruptcy in 1977, three units were passed onto the Soo Line Railroad, the Milwaukee Road's successor.[1]
Preservation[edit]
One unit is preserved:
