In 1966, EMD updated its locomotive catalog with entirely new models, all powered by the new 645 diesel engine. The SD40 had 3,000 hp from a tur- bocharged V16. 856 examples of this locomotive model were built for Amer- ican railroads, 330 were built for Canadian railroads, and 72 were built for Mexican railroads.
