HO RTR SD40T-2 with DCC and Sound SP 1990s #8370 (ATH72166)

An HO-scale Ready-To-Run SD40T-2 diesel locomotive reproducing SP's 1990s tunnel-motor in road number 8370. This model includes onboard Econami Sound by SoundTraxx and full DCC compatibility, delivering lifelike engine, horn, and bell sounds with smooth digital control. The exterior captures era-accurate details with LED lighting, see-through cab windows, photoetched windshield wipers, and separately applied grab irons and air tanks for a convincing, close-to-prototype appearance.

Under the hood, the loco delivers dependable performance: six axles driven by an all-wheel-drive chassis, a five-pole motor with flywheels and a multi-link drivetrain for quiet operation, and nickel-plated, blackened machined wheels with RP25 contours. It uses McHenry scale knuckle couplers and is DCC-ready with a 21-pin NEM Quick Plug for easy setup. The sound-equipped version operates in both DC and DCC modes, offering full DCC functionality and adjustable CVs; some configurations include Primed for Grime weathering to mimic wear and fading from service, with a recommended minimum radius of 22 inches for smooth operation.
