HO GEN GP39-2 PH I Locomotive ATSF #3640 (ATHG-1964)

This HO-scale GP39-2 Phase I diesel locomotive in Santa Fe livery (ATSF #3640) is a faithful representation of the mid-1970s EMD road switcher for HO layouts. It features a see-through cab interior, LED lighting, and a detailed fuel tank mounted on a heavy die-cast frame for realistic weight and traction. DCC-ready with Quick Plug plug-and-play technology and a 21-pin NEM connector makes digital setup straightforward, while a Genesis driveline with a 5-pole motor, all-wheel drive, and RP25 wheels deliver smooth, quiet operation on standard HO track.

ATSF styling captures an early-phase 1 body with a rear-mounted fuel tank, large anticlimber, Stratolite cab beacon (effect in DCC), switcher-style walkway steps, and a Leslie 3-chime horn. Additional detail includes etched metal grilles, body-mounted McHenry scale knuckle couplers (Kadee-compatible), and precise paint and printing. Sound-equipped versions add Tsunami2 sound with dual speakers and full DCC functionality, with CVs for MU lashups, while the 18-inch minimum turning radius keeps operation compatible with most HO layouts.
