HO SD40R Locomotive Southern Pacific Kodachrome #7384 (ATH73635)

HO-scale SD40R Locomotive in Southern Pacific Kodachrome livery, road number 7384, is a highly detailed model designed to bring the look and performance of the prototype to an HO layout. It’s built for realistic operation, featuring LED lighting, see-through cab windows, photo-etched windshield wipers, and fine-scale handrails with separately applied grab irons and air tanks. The model is DCC-ready with a Quick Plug 21-pin NEM connector, and sound-equipped versions include an onboard DCC decoder with SoundTraxx Econami sound for authentic engine, horn, and bell sounds, while conventional DC operation is supported as well.

On the rails, it delivers smooth, reliable performance with all-wheel drive and precision gears for quiet running, RP25-contoured wheels for compatibility with popular HO track, and McHenry scale knuckle couplers (Kadee-compatible). Prototypical details include a 4,000-gallon fuel tank, frame-mounted bell, and a highly detailed injection-molded body with see-through cab windows. For layout planning, a minimum radius of 18 inches is recommended (22 inches for best operation), making this SP Kodachrome SD40R a strong choice for recreating era-specific locomotive power on your HO layout.
