HO SD45T-2 Locomotive with DCC and Sound SP Speed Letter #9343 (ATH86973)

HO Scale SD45T-2 Locomotive with DCC and Sound in SP Speed Lettering, road number 9343, is a detailed HO-scale model of SP’s six-axle tunnel motor. This DCC-ready locomotive is designed for operation on modern layouts and can be enjoyed with onboard sound, reproducing the prototype’s rugged look and authentic performance. Exterior details include a nose headlight, the modified L-window cab, roof-mounted A/C and bell, a long-hood Nathan P-3 horn, walkways with ditch lights, a large front plow, and a prominent anticlimber, all finished in the era’s Speed Lettering scheme.

Under the shell, craftsmanship meets performance: fine-scale handrails, etched windshield wipers, separate air tanks, LED lighting, and see-through cab windows. The drive uses an all-wheel pickup and a 5-pole motor with flywheels and a multi-link drivetrain for smooth, quiet operation, while the DCC-ready chassis accepts a 21-pin NEM plug and rides on nickel-plated, blackened machined wheels with RP-25 contours for reliable tracking. Sound-equipped versions add an onboard DCC decoder with SoundTraxx Economi sound that works in both DC and DCC, with full DCC functionality when in DCC mode and engine, horn, and bell sounds in DC. The SP SD45T-2 prototype—six-axle diesel-electric, roughly 3600 horsepower from a 20-cylinder 645-series engine—earned the Tunnel Motors nickname and is represented here for HO layouts, which benefit from a minimum radius of 18 inches (22 inches recommended) to reproduce its size and presence on curves.
