HO GEN SD90MAC Locomotive UP #3772 (ATHG-1917)

HO-scale Genesis EMD SD90MAC Locomotive in Union Pacific livery (UP 3772). This fully assembled, ready-to-run HO model from the Athearn Genesis line captures the prototype’s power and detail, with a heavy die-cast frame for substantial pulling power and authentic branding that enhances any layout.

Power and performance come from a Genesis driveline with a 5-pole motor, all-wheel drive and electrical pickup, LED lighting, and a faithful detailing package that includes flexible trainline hoses, etched see-through steps, lit number boards and truck lights, a full cab interior, windshield wipers, scale handrails, walkways and more. It’s DCC-ready with Quick Plug plug-and-play technology and a 21-pin NEM connector, and offers road-number- and UP-specific variations such as front ditch lights, nose-door options (with or without windows), and multiple horn types to match prototype configurations. The model rides on RP25-contoured wheels, uses body-mounted knuckle couplers, and is designed for HO curves as small as 18 inches (22 inches recommended), delivering realistic operation on busy layouts.
