HO SD75M Locomotive BNSF #231 (ATHG71131)

HO-scale SD75M Locomotive in BNSF livery, road number 231, is a highly detailed model designed for HO layouts. It captures late-era Santa Fe heritage with BNSF patches and road-number-specific detailing—231 features large cab numbers and yellow frame stripes—along with weathering cues like faded base colors, round deck-mounted ditch lights, a Sinclair antenna, and early EMD trucks with hidden bearings. Presented as the unit did in its late career, before changing hands, this model provides an authentic centerpiece for a Santa Fe/BNSF freight roster on a modern layout.

Built for realism and reliable operation, the SD75M includes see-through cab windows with a full interior, fine-scale Celcon handrails, and body-mounted scale knuckle couplers (Kadee-compatible). It is DCC-ready with Quick Plug plug-and-play technology and a 21-pin NEM connector, and features LED lighting, a heavy die-cast frame, and a Genesis driveline with all-wheel drive and electrical pickup for smooth, quiet power. A sound-equipped version adds onboard Tsunami2 sound with full NMRA-compatible functions, while grime-ready variants offer an in-service look for weathering enthusiasts. The model suits HO layouts with a minimum 18-inch radius (22 inches recommended) for dependable operation across typical track layouts.
