HO SD40T-2 Locomotive D&RGW #5407 (ATH71753)

HO-scale Denver & Rio Grande Western SD40T-2 tunnel-motor locomotive, number 5407, is a meticulously detailed replica designed for HO railroaders seeking an authentic representation of this prototype. Known as a tunnel motor for its enhanced cooling in tunnels, this six-axle diesel-electric captures the distinctive silhouette and era-specific styling, including an 88-inch nose with non-operational class lights and a gyralight effect that can be activated in DCC operation. See-through cab windows and finely tuned detailing complete the model, making it a striking centerpiece for both display and on-layout operation.

Inside, the model is built for smooth, reliable running with a robust drivetrain and a highly detailed injection-molded body. It rides on nickel-plated, RP25-contoured wheels and uses McHenry scale knuckle couplers, while LED lighting and a DCC-ready 21-pin NEM plug simplify digital operation. The design accommodates 18-inch minimum-radius curves (22 inches recommended) for versatility on typical layouts. Sound-equipped variants feature onboard DCC decoders with SoundTraxx Econami for authentic engine, horn, and bell sounds when run in DC or DCC.
