Athearn Genesis HO Scale EMD GP39-2 Santa Fe ATSF #3621 - DCC/Sound

The Athearn Genesis HO Scale EMD GP39-2 Santa Fe ATSF #3621 - DCC/Sound is an HO scale diesel locomotive from Athearn Genesis. It is decorated for Santa Fe.

Factory-equipped with DCC and sound.

The Atchison, Topeka and Santa Fe Railway was one of the largest purchasers of EMD GP39-2 diesel locomotives. Built during the 1974–1984 production period, the GP39-2 combined a turbocharged 12-cylinder EMD 645E3 engine with a four-axle road-switcher design, producing approximately 2,300 horsepower.

Originally intended for fast freight assignments, Santa Fe's GP39-2 locomotives became versatile performers on local freight trains, road-switching assignments, and other general freight duties. Their combination of power, fuel efficiency, and four-axle flexibility made them useful throughout the railroad's system.

Athearn Genesis reproduces ATSF #3621 in its early Phase I configuration, featuring railroad-specific equipment and the classic Santa Fe appearance associated with the railroad's original GP39-2 locomotives.
