HO F7B Locomotive Freight ATSF #266A (ATHG-1715)

HO Scale F7B Freight Locomotive in Santa Fe (ATSF) livery, numbered 266A, is a detailed replica of General Motors’ EMD F-unit diesel locomotive. It captures the bulldog-nose body style and classic carbody design that defined early diesel-powered freight service, making it a striking centerpiece for Santa Fe-era layouts or any freight-focused roster.

Under the shell, the model features a heavy die-cast frame, Genesis driveline with a 5-pole skew-wound motor, and all-wheel drive for smooth, quiet operation and reliable pulling power. It’s designed for modern layouts with LED lighting, RP25-contoured wheels, and body-mounted scale knuckle couplers that are Kadee-compatible, plus see-through cab windows and a full cab interior for realism. The model is DCC-ready with Quick Plug 21-pin NEM connector, and it includes road-name specific ATSF detailing such as Phase 1 features, dynamic brakes, 36-inch fans, Leslie A-200 horns, a radio antenna, and skirts that can be removed for prototype accuracy. Sound-equipped versions add an onboard DCC decoder with Tsunami2 sound and dual cube speakers, delivering authentic engine, horn, and bell sounds (some functions may be limited in DC). Minimum radius is 18 inches, with a 22-inch radius recommended for best performance.
