HO SD40T-2 Locomotive with DCC & Sound, SP #8281 (ATH71849)

HO-scale SD40T-2 tunnel-motor locomotive in Southern Pacific livery is designed for HO layouts that prize realism and modern control. This DCC-equipped model includes a built-in SoundTraxx Econami sound decoder, delivering authentic engine, horn, and bell sounds, and it can operate on both DC and DCC layouts with full DCC functionality when in DCC mode. The model is DCC-ready with 21-pin NEM Quick Plug technology for easy installation, and it features SP-style front and rear lighting with a Gyralight effect, a cab with see-through windows, and a finely detailed body that captures the prototype look.

Beyond appearance, it offers practical, model-railroading benefits: fine-scale handrails, photo-etched windshield wipers, see-through dynamic brake fans, LED lighting, and nickel-plated, blackened wheels with RP25 contours for reliable tracking. The drivetrain uses a 5-pole motor with flywheels and a multi-link design for smooth, quiet operation, and the chassis accepts a Genesis motor retrofit kit for higher performance. It’s designed for an 18-inch minimum radius (22 inches recommended) and features all-wheel drive, McHenry operating scale knuckle couplers, and other prototypical details. For weathering enthusiasts, the finish provides an excellent starting point for adding grime or rust to reproduce a well-used tunnel-motor in service.
