The Santa Fe Railway's EMD GP39-2 Locomotives

Electro-Motive Division manufactured the GP39-2 between 1974 and 1984 as a fuel-efficient, four-axle diesel-electric road switcher. Powered by a turbocharged 12-cylinder EMD 645E3 prime mover producing 2,300 horsepower, the locomotive provided an alternative to larger 16-cylinder road diesels.

Santa Fe purchased substantial numbers of GP39-2 locomotives for freight service. Although initially used on faster freight assignments, these versatile units became familiar sights on local trains, industrial branches, and road-switching duties.

Athearn Genesis models ATSF #3621 in its early Phase I configuration, reproducing the railroad's distinctive fuel tank placement, walkway steps, front anticlimber, and other identifying details.
