HO U50 Locomotive SP #9950 (ATHG41078)

HO Scale Southern Pacific U50 Locomotive #9950 is a highly detailed, ready-to-run model that reproduces SP's potent 5,000-horsepower U50, powered by two 2,500-hp prime movers. Designed for HO layouts, it provides an authentic centerpiece for Sunset Route-era freight scenes and other SP-era operations.

The model features illuminated truck lights, classification lights, number boards, and see-through air intakes, along with a full cab interior and a heavy die-cast frame for traction. It runs on RP25-contoured wheels for reliable operation on common HO track and is DCC-ready with Quick Plug technology and a 21-pin NEM connector. Sound-equipped versions add an onboard DCC decoder with SoundTraxx Tsunami2 and four-cube speakers for realistic locomotive audio. For layout compatibility, minimum radius is 18 inches with 22 inches recommended for smooth, confident operation.
