HO GP9 Locomotive with DCC & Sound, UP #165 (ATHG82824)

An HO-scale GP9 diesel locomotive with DCC and sound in Union Pacific livery (UP #165), this model brings a classic mid‑century switcher to life on an HO layout. It features a SoundTraxx Tsunami2 onboard sound system with two cube speakers for realistic engine, horn, and bell effects, and it runs on both DC and DCC layouts with NMRA‑compatible functions. A 21‑pin NEM plug‑and‑play connector supports quick DCC upgrades for easy, authentic operation.

The GP9 is built around a heavy die‑cast frame for solid traction, with RP25 wheel contours and body‑mounted knuckle couplers for a prototypical look and smooth, reliable operation. It offers prototype‑accurate detailing such as see‑through cab windows, etched grilles, and a detailed fuel tank, and ships fully assembled and ready to run. Designed for HO layouts, it handles modest curves with a minimum radius of 18 inches (22 inches recommended) to ensure smooth performance on a wide range of tracks.
