HO SD40T-2 Locomotive D&RGW #5402 (ATH71752)
HO-scale SD40T-2 tunnel-motor locomotive in D&RGW livery, number 5402, is a detailed HO model that recreates the six-axle diesel-electric prototype used in tunnel service during the 1970s. Designed for HO model railroading, this locomotive offers an authentic silhouette and prototype-grade detailing, letting you bring a classic tunnel motor to your layout with confidence.
Key features include LED lighting, see-through cab windows, fine-scale handrails, and an all-wheel-drive chassis powered by a 5-pole motor for smooth, quiet operation. The model is DCC-ready with a 21-pin NEM plug and can accommodate sound decoders for authentic engine, horn, and bell sounds, while remaining compatible with DC operation. Prototypical touches such as the 88-inch nose with class lights and gyralight, cab-mounted horn, and RP25-wheel profiles enhance realism and running reliability on standard HO track, with weathering-ready options to suit a lived-in roster.
