HO SD40T-2 Locomotive UP #2929 (ATH73042)

HO Scale Union Pacific SD40T-2 Tunnel Motor Locomotive, Number 2929. This highly detailed, ready-to-run model reproduces UP’s renumbered SP tunnel motor for HO layouts, delivering an authentic representation of a classic prototype in Union Pacific livery.

UP-specific detailing includes an 88-inch nose with brake wheel, cab-mounted air conditioning, front ditch lights, a UP-style front plow, a modified front L-window, and an M3 horn. The SD40T-2 features fine-scale handrails, photo-etched windshield wipers, see-through dynamic brake fans, and separately applied air tanks, all mounted on a highly detailed injection-molded body. It rides on nickel-plated, blackened machined wheels with RP25 contours for reliable operation on popular HO track, and uses McHenry operating-scale knuckle couplers for realistic handling. The locomotive is DCC-ready with 21-pin NEM Quick Plug technology and is available in sound-equipped versions powered by Tsunami2 decoders, delivering engine, horn, and bell sounds in both DC and DCC. A 5-pole motor with flywheels and a multi-link drivetrain provides smooth, quiet operation with all-wheel drive, and the recommended minimum radius is 22 inches, making it well suited for mid-sized HO layouts and yard work.
