HO GEN AC4400CW Locomotive FSRR #4427 (ATHG-2049)

ATHEARN Genesis GE AC4400CW Diesel Locomotive in FSRR livery for HO scale is a detailed, prototype-accurate model designed to bring late-20th-century power to an HO layout. Replicating GE’s AC4400CW from 1993 to 2004, this locomotive captures the era’s distinctive styling and paint schemes, including FSRR’s road-numbered unit 4427, with tooling that reflects the real-world variations produced—2,834 examples were built in total.

The model is DCC-ready with Quick Plug plug-and-play technology using a 21-pin NEM connector and a Genesis driveline featuring a five-pole skew-wound motor for smooth, quiet operation. A heavy die-cast frame provides traction, while RP25 wheels and all-wheel electrical pickup ensure reliable running on common HO track. Lighting is LED-enabled with illuminated number boards, ground lights, and walkway lights, complemented by see-through cab windows, a full cab interior, etched walkway steps, Celcon handrails, windshield wipers, lift rings, and wire grab irons. Couplers are McHenry scale knuckle (Kadee-compatible), and many models offer onboard Tsunami2 sound with full DCC functionality and adjustable CVs (CV chart included). Road-name–specific variations cover CP, UP, NS, CEFX, BNSF, and FSRR schemes, so the locomotive can represent a broad modern-era roster, while an 18" minimum radius and 22" recommended radius ensure smooth operation on typical HO layouts.
