HO RTR SD40T-2 Locomotive SP #8494 (ATH72069)

An HO-scale ready-to-run SD40T-2 locomotive in Southern Pacific livery (SP #8494), this model reproduces the six-axle diesel-electric tunnel-motor with careful attention to prototype details. The six-axle configuration is powered by a 16‑cylinder EMD 645E3 engine delivering 3,000 horsepower, and it incorporates the cooling-system upgrades and rear radiator intakes that define the tunnel-motor design. With road-number-specific detailing and authentic SP color, it serves as a faithful centerpiece for any HO-scale freight roster on a home layout.

On the rails, the model emphasizes realism and reliable performance: LED lighting, see-through cab windows, fine-scale handrails, and a range of separately applied details. It is DCC-ready with a 21-pin NEM Quick Plug, and features an all-wheel-drive drivetrain with a 5-pole motor and flywheels for smooth, quiet operation. Authentic touches include a full gyralight package on the front and rear, plows on both ends, and a slanted Nathan P-3 horn, plus McHenry scale knuckle couplers and RP25-contoured wheels for dependable tracking on standard HO track. The recommended minimum radius is 22 inches, with replacement parts available to support ongoing maintenance. A speed recorder is mounted to the appropriate axle per prototype.
