HO GEN GP39-2 Phase I Locomotive ATSF #3655 (ATHG-1965)

This HO-scale GP39-2 Phase I locomotive in Santa Fe livery, road number 3655, is an authentic Athearn model designed for HO layouts, capturing the look of a mid-1970s GP39-2 road switcher. The Phase I body, rear-mounted fuel tank, large anticlimber, and Stratolite cab beacon are faithfully reproduced, while see-through cab windows reveal a full interior and fine-scale detailing like etched handrails, wire grab irons, lit number boards, and LED lighting for added realism.

On the rails, the model is built for smooth, reliable performance with a heavy die-cast frame, all-wheel drive, and precise gearing. It rides on RP25-contoured wheels for compatibility with popular HO tracks and includes DCC-ready Quick Plug plug-and-play technology with a 21-pin NEM connector for easy decoder installs. Body-mounted McHenry scale knuckle couplers (Kadee-compatible) and LED lighting deliver prototypical operation, while a Tsunami2 sound-equipped version adds onboard sound with dual speakers and full NMRA-compatible functions; CVs can be adjusted to tailor performance, and a minimum 18-inch radius is recommended for best results.
