HO GEN AC4400CW Locomotive w/DCC & SOUND FSRR #4427 (ATHG-2067)

HO-scale GE AC4400CW Diesel Locomotive with DCC and Sound in FSRR #4427. This HO model from the Athearn Genesis line faithfully reproduces GE’s modern freight locomotive for HO layouts, delivering an authentic look and operation with built‑in sound and DCC control for a realistic, ready‑to‑run experience.

The model emphasizes prototype‑accurate detailing and reliable performance. It features LED lighting with illuminated number boards and front/rear walkway lights, see‑through cab windows, and a full cab interior. It’s DCC‑ready with a Quick Plug 21‑pin interface and a Genesis driveline—5‑pole skew‑wound motor, precision flywheels, and a multi‑link drivetrain—for smooth, quiet operation on a robust, heavy die‑cast frame with all‑wheel drive and NMRA‑compatible CVs. The sound‑ready version adds a DCC decoder with Tsunami2 sound and dual speakers for lifelike engine, horn, and bell audio; McHenry scale‑knuckle couplers (Kadee‑compatible) and RP25 wheel contours further enhance realism. Minimum radius is 18 inches, with 22 inches recommended for optimal performance on most HO layouts.
