HO F7A Locomotive with DCC and Sound Freight SNCT #101 (ATHG-1723)

HO-scale F7A diesel locomotive with DCC and sound, road-number 101, bringing General Motors’ iconic first-generation F-unit to life on an HO layout. This model pairs a DCC decoder with SoundTraxx Tsunami2 sound and two cube speakers for authentic engine, horn, and bell effects, while running on both DC and DCC with NMRA-compatible functions in DCC mode. See-through cab windows reveal a full cab interior, and the exterior detail—etched metal grilles, LED lighting, and a heavy die-cast frame—captures the distinctive bulldog-nose silhouette and delivers a convincing, ready-to-run presence.

Under the hood lies a Genesis driveline with a 5-pole skew-wound motor, precision-machined flywheels, and a multi-link drivetrain for smooth, quiet operation with all-wheel drive and reliable electrical pickup. It uses body-mounted scale knuckle couplers (Kadee-compatible), RP25 wheels for compatibility with popular track brands, and a 21-pin NEM plug for quick DCC setup. Painted to prototype schemes and primed for grime, it’s a strong weathering starting point, designed for HO layouts with a minimum 18-inch radius (22 inches recommended) for optimal performance.
