HO GEN AC4400CW Locomotive UP #5630 (ATHG-2043)

An HO-scale GE AC4400CW diesel locomotive in Union Pacific livery, number 5630, from Athearn’s Genesis line. This detailed, ready-to-run model captures the look of a modern freight locomotive with prototype-accurate paint and detailing, making it a standout centerpiece for HO layouts.

Designed for flexible operation, this AC4400CW is DCC-ready with Quick Plug plug-and-play technology and a 21-pin NEM connector for easy decoder installation. LED lighting includes illuminated number boards, ground lights, and walkway lights, plus see-through cab windows and a full interior. The Genesis driveline combines a five-pole motor, precision flywheels, and a heavy die-cast frame for smooth, powerful, quiet operation, with all-wheel drive and reliable current pickup. Sound-equipped variants add an onboard DCC decoder with Tsunami2 sound and dual speakers for authentic engine, horn, and bell sounds in DCC (and usable in DC), while road-name UP features cover as-delivered schemes with hi-mounted number boards, large GPS dome, and a walkway capacitor box. A minimum 18-inch radius (22 inches recommended) keeps performance steady on typical HO layouts, and the model is well-suited for grime-weathering to add realism.
