HO GEN AC4400CW Locomotive w/DCC & SOUND, NS #3990 (ATHG-2068)

HO-scale GE AC4400CW Locomotive with DCC & Sound in NS #3990, a detailed Athearn Genesis model designed to bring a modern freight locomotive to life on HO layouts. It combines prototypical detailing with functional realism, featuring DCC-ready Quick Plug technology via a 21-pin NM connector, authentic paint schemes, and lifelike LED lighting, including illuminated number boards, ground and walkway lights, plus a full cab interior visible through see‑through cab windows.

On the tracks, this model delivers solid, quiet performance with a Genesis driveline—5-pole motor, machined flywheels, and all‑wheel drive—housed in a heavy die-cast frame for strong pulling power. It runs on DC or DCC, with CVs to tailor speed and function, and uses McHenry scale knuckle couplers (Kadee-compatible) and RP25 wheels for reliable operation on common HO track. Designed for HO layouts, it typically requires an 18" minimum radius (22" recommended) and offers road-number‑specific details that make it a convincing centerpiece for a modern-era roster.
