HO SD40-2 Locomotive OWTX #9954 (ATH-1806)

HO-scale SD40-2 Locomotive in OWTX livery (#9954) is a ready-to-run, highly detailed model designed for HO layouts. It is offered in both non-sound DCC-ready form and a sound-equipped variant, delivering authentic branding, realistic lighting, and dependable performance for diorama displays or productive operating sessions.

On the rails, the model features a heavy die-cast frame for traction, all-wheel drive with precision gears, RP25-contoured wheels, and a 5-pole motor with flywheels for smooth, quiet operation. It ships as a DCC-ready unit with a 21-pin NEM plug and McHenry knuckle couplers for reliable coupling. The OWTX version adds a mid-production body with corrugated grilles, cab-mounted gyralight, nose-mounted headlight, extended-range dynamic brakes, whip antenna, a 4000-gallon fuel tank, Leslie 5-Chime horn, and MU hose trays for authentic detailing; some road-number variations may feature different antennas or horns. The sound-equipped model includes an onboard DCC decoder with SoundTraxx Econami and a single speaker, delivering engine, horn, and bell sounds in DCC (with limited functions on DC). Minimum running radius is 18 inches (22 inches recommended).
