HO SD40T-2 Locomotive with DCC and Sound, UP #2930 (ATH73143)

An HO scale SD40T-2 tunnel-motor locomotive in Union Pacific livery with road number 2930, this ready-to-run model captures the look and character of UP’s tunnel-motor fleet. It features onboard SoundTraxx Tsunami2 sound, LED lighting, and a DCC-ready 21-pin interface, blending authentic UP detailing such as an 88-inch nose with a brake wheel, front ditch lights, a UP-style front plow, and a cab-mounted air conditioner. Fine-scale handrails, see-through radiator grilles, photo-etched windshield wipers, and independently applied air tanks add realism, while RP25 wheels and McHenry operating-scale knuckle couplers ensure smooth operation on standard HO track.

Built for smooth, quiet performance, the model uses all-wheel drive with precision gears, a 5-pole motor with flywheels, and a multi-link drivetrain. It’s designed for HO layouts with a 22-inch minimum radius, and it runs on both DC and DCC; in DCC mode it offers full function control and authentic engine, horn, and bell sounds. Prototype notes reflect the SD40T-2’s six-axle design and distinctive cooling arrangement, making this UP unit a compelling centerpiece for UP-era scenes or SP-to-UP transitions, especially when paired with other locomotives in lashups.
