HO SD40T-2 Locomotive Union Pacific #2923 (ATH73041)

Union Pacific HO-scale SD40T-2 Locomotive No. 2923 is a detailed, ready-to-run representation of the famous tunnel-motor. This UP-renumbered SP heritage unit from the late 1990s is designed for realistic operation on standard layouts, with a minimum 22-inch radius. It features the characteristic UP livery and period-accurate details such as the 88-inch nose with brake wheel, cab-mounted A/C, front ditch lights, and a UP-style front plow.

Inside, the model emphasizes authentic detailing and dependable performance: finely rendered handrails, photo-etched windshield wipers, see-through dynamic brake fans, and separate air tanks, all on a sturdy, all-wheel-drive chassis with a 5-pole motor and flywheels. It comes fully assembled and ready to run, with nickel-plated, RP25-contoured wheels and McHenry operating knuckle couplers, plus DCC-ready compatibility via a 21-pin NEM plug. For sound enthusiasts, sound-equipped versions include a Tsunami2 decoder with engine, horn, and bell sounds and full DC/DCC operation, while maintaining smooth, quiet performance on a wide range of layouts.
