In 1966, EMD updated its locomotive catalog with entirely new models, all powered by the new 645 diesel engine. The SD39 had 2,300 hp from a turbocharged V12. The SD39 had the smallest prime mover of the SD locomotives in the EMD catalog. 54 were built for American railroads.

The 26 SD39s owned by Southern Pacific spent a significant amount of time working the steep grades of Tehachapi. In later years, the venerable locomotives were regulated to hauler service in the LA basin area.
