HO SD45T-2 Locomotive with DCC and Sound Union Pacific #4825 (ATH86968)

HO scale SD45T-2 Locomotive with DCC and Sound in Union Pacific livery, road number 4825, is a six-axle diesel-electric model designed for authentic operation on modern layouts. It reproduces UP’s tunnel-motor heritage with features like a nose headlight, a modified late Dash-2 cab with an optional L-window, roof-mounted air conditioning, and a Nathan P-3 horn, plus pilot-mounted ditch lights, a large front plow, and a small anticlimber. The model reflects prototype detailing, including fixed see-through cab windows, fine-scale handrails, and welded equipment, delivering a striking, highly realistic UP silhouette.

The locomotive combines robust detailing with advanced performance. It includes LED lighting and, in sound-equipped versions, an onboard DCC decoder with SoundTraxx Economi sound that runs on both DC and DCC, with full DCC functionality when operating in DCC mode. Users will enjoy excellent slow-speed control, NMRA-compatible functions, and the ability to program MU lashups. The drive system features all-wheel drive with precision gears, a 5-pole motor with flywheels, and nickel-plated, blackened machined wheels on RP25-contoured axles for smooth, quiet operation. Additional details such as McHenry scale knuckle couplers, separately applied air tanks, wire grab irons, see-through radiator grilles, and DCC-ready 21-pin NEM plug enhance realism and ease of use. The prototype’s tunnel-motor heritage is complemented by a minimum 18" radius with a recommended 22" radius for reliable operation on common tracks.
