HO SD40T-2 Locomotive with DCC and Sound (Speed Lettering #8256) (ATH73153)

An HO-scale SD40T-2 tunnel-motor diesel locomotive with onboard DCC and Tsunami2 sound, built to reproduce the Southern Pacific Speed Lettering era on your layout. This ready-to-run model captures the 1991 Speed Lettering updates, including front ditch lights and a horn relocated to the rear hood, along with a simplified lighting package designed to reduce maintenance. It runs in both DC and DCC modes, delivering authentic sound and smooth operation as soon as it’s on the rails.

Detail-rich features include fine-scale handrails, see-through radiator grilles and dynamic brake fans, LED lighting, and separately applied air tanks. The powertrain uses a robust five-pole motor with flywheels and an all-wheel-drive drivetrain for quiet, reliable operation, plus McHenry scale-knuckle couplers and RP25 wheels for compatibility with common HO track. Designed for 22" radius curves, the model supports full DCC function control with CV-tuning and also delivers engine, horn, and bell sounds in DC mode, making it a compelling centerpiece for SP Speed Lettering-era layouts.
