HO SD40T-2 Locomotive with DCC & Sound, NECR #3317 (ATH71856)

HO-scale SD40T-2 Locomotive with DCC & Sound in NECR #3317 is a detailed HO model of GM’s iconic six-axle tunnel-motor. It reproduces the 3,000-horsepower powerplant and includes an onboard DCC decoder with SoundTraxx Econami sound, delivering authentic engine, horn, and bell sounds and full DCC functionality for realistic operation on both DC and DCC layouts.

Prototype-accurate detailing includes fine-scale handrails, see-through cab windows, LED lighting, and a highly detailed injection-molded body mounted on nickel-plated wheels with an all-wheel-drive chassis for smooth, quiet performance. The model captures distinctive tunnel-motor features such as rear radiator intakes and see-through radiator grilles, and it arrives in Legendary Liveries to evoke classic historical schemes. Designed for HO layouts, it supports multi-unit lashups and weathering-ready styling, with a minimum recommended radius of 18 inches (22 inches for best results).
