HO GP18 Locomotive with DCC and Sound CR #7496 (ATHG-1371)

HO GP18 Locomotive with DCC and Sound, road number 7496, is a detailed HO-scale diesel model designed to faithfully reproduce the late-1950s GP18 switcher. It houses an onboard DCC decoder with SoundTraxx Tsunami2 and dual cube speakers, delivering authentic engine, horn, and bell sounds that operate in both DC and DCC layouts. Quick Plug plug-and-play technology with a 21-pin NEM connector keeps wiring simple, and the Genesis driveline—with a 5-pole skew-wound motor, precision machined flywheels, and a multi-link drivetrain—delivers smooth, powerful performance.

On the rails it blends solid realism with practical running power: heavy die-cast construction for traction, all-wheel drive with reliable current pickup, and RP25-profile wheels for smooth operation on popular HO track. It rides on Blomberg-B trucks, uses body-mounted McHenry-scale knuckle couplers (Kadee-compatible), and features see-through cab windows with a full interior, etched radiator and fan grills, fine-scale Celcon handrails, and prototype-inspired detailing across road-number variations. Bidirectional LED lighting maintains constant headlight brightness, and it’s designed for HO layouts with a minimum radius of 18 inches (22 inches recommended), making it ready to pull realistic consists on a wide range of layouts.
