HO SD40T-2 Locomotive with DCC & Sound, UP #2923 (ATH73141)

HO scale SD40T-2 Locomotive with DCC & Sound in Union Pacific livery is a detailed, ready-to-run model of EMD’s tunnel-motor class. This UP 2923 unit represents a former SP locomotive renumbered after UP’s 1996 takeover, and it captures a distinctive profile with an 88-inch nose, front ditch lights, a UP-style plow, and a cab-mounted air conditioner. The model includes onboard DCC decoding with SoundTraxx Tsunami2 sound and runs on both DC and DCC layouts, with full DCC function control when used in DCC mode. It arrives fully assembled and decorated, with nickel-plated, blackened wheels and RP25 contours for smooth operation on standard HO track.

Inside, the SD40T-2 is built for reliable, quiet operation. It features a 5-pole motor with flywheels and a multi-link drivetrain, all-wheel electrical pickup, fine-scale handrails, photo-etched windshield wipers, see-through dynamic brake fans, and separately applied air tanks and grab irons. The injection-molded body is highly detailed and painted to resemble the prototype, including see-through radiator grilles and a rear truck gearbox specific to the tunnel motor, plus McHenry operating scale knuckles. A 22-inch minimum radius is recommended to ensure smooth handling on typical layouts, and the model is MU-ready for lashups and CV-tunable to tailor performance and sound.
