HO GP18 Locomotive DCC and Sound Conrail #7499 (ATHG-1372)

HO GP18 Locomotive with DCC & Sound in Conrail livery, number 7499. This HO-scale GP18 model reproduces the late-1950s switcher with an onboard DCC decoder and SoundTraxx Tsunami2, delivering authentic engine, horn, and bell sounds on both DC and DCC layouts. Dual cube speakers provide clear, robust audio as you operate the locomotive.

Built for prototypical accuracy and dependable performance, the model features see-through cab windows with a full interior, Blomberg-B trucks, and a heavy die-cast frame for traction. It rides on RP25-contoured wheels with all-wheel electrical pickup and body-mounted McHenry scale-knuckle couplers (Kadee compatible) to simplify operations on standard HO track. The unit is DCC-ready with Quick Plug plug-and-play and a 21-pin NM connector, and CV-based tuning supports full DCC functions. For road-number accuracy, this Conrail 7499 variant reproduces features such as a hood-mounted air filter box and modified left-side skirting, reflecting its lineage from ex-Lehigh Valley #305. The GP18 uses a five-pole skew-wound motor for steady, quiet performance and is designed for HO layouts with a minimum 18-inch radius (22 inches recommended).
