HO AC4400CW Locomotive UP 6812 (ATHG31692)

HO-scale GE AC4400CW Locomotive in Union Pacific livery, road number 6812, is a detailed model designed for HO layouts with ready access to digital control. The 6812 variant captures its original appearance, including the red frame stripe, a Leslie 3-chime horn, a large roof-mounted GPS dome, and a walkway capacitor box.

Designed for realism and reliability, the model features DCC-ready Quick Plug technology with a 21-pin NEM connector for easy digital operation, a Genesis drivetrain with a 5-pole skew-wound motor, precision flywheels, and all-wheel drive for smooth, quiet performance. LED lighting includes illuminated number boards, ground lights above the front truck, and front and rear walkway lights, while see-through cab windows reveal a full interior. Additional details include etched walkway steps, scale handrails, windshield wipers, lift rings, wire grab irons, and a detailed fuel tank. RP25 wheel contours ensure compatibility with most HO track, and Kadee-compatible scale knuckle couplers provide reliable operation. Some models are sound-equipped with onboard Tsunami2 sound and dual speakers, offering full DCC functionality with adjustable CVs and a CV chart included. The tooling reflects prototype references and UP’s AC4400CW variations, including early-production styling.
