HO AC4400CW Locomotive with DCC and Sound UP #6812 (ATHG31792)

HO-scale Union Pacific AC4400CW Locomotive with DCC and Sound, road number 6812, is a detailed HO model designed to capture UP’s early-production power in a faithful, ready-to-run form. The 6812 variant reproduces the red frame stripe and includes era-specific details such as a Leslie 3-chime horn, a large roof-mounted GPS dome, and a walkways capacitor box, giving it authentic presence on a UP-themed layout.

Designed for realistic operation, this model blends prototype-level detailing with advanced electronics. It is DCC-ready with Quick Plug and a 21-pin NEM connector for straightforward decoder upgrades, and the sound-equipped version features an onboard DCC decoder with SoundTraxx Tsunami2 and dual cube speakers for rich, immersive audio in both DC and DCC modes. The drivetrain uses a Genesis five-pole skew-wound motor, a heavy die-cast frame for traction, and all-wheel drive with precise gearing for smooth, quiet running. Fine details such as etched walkways, see-through cab windows, a full cab interior, and McHenry scale knuckle couplers complement the model’s realism and give it standout presence on any layout.
