HO GP7 Locomotive with DCC and Sound - Rock Island #1204 (ATHG-2289)

HO scale EMD GP7 diesel locomotive with DCC and sound in Rock Island livery, number 1204. This detailed model brings the GP7’s classic diesel profile to HO layouts, pairing a SoundTraxx Tsunami2 decoder with dual speakers for realistic engine, horn, and bell sounds. It runs on DC or DCC layouts and uses a 21-pin NEM connector for quick plug-and-play installation, with a Genesis driveline, a 5‑pole motor and precision flywheels, plus a heavy die-cast frame for smooth, powerful operation.

Road-number-specific details for 1204 include a dark maroon paint scheme with pinstripes and yellow ends, MARS headlights, slotted skirts, RI-style fuel-tank spark arrestors, and sloped pilot plates. The model features see-through cab windows with a full interior, fine-scale handrails, etched grilles, and body-mounted McHenry scale knuckle couplers (Kadee-compatible). It rides on accurately detailed trucks, uses RP25 wheel contours for reliable operation on HO track, and is designed for an 18-inch minimum radius, making it ready to run on standard layouts and suitable for MU lashups and realistic DC or DCC operation.
