HO F7A Locomotive, Freight LN #824 (ATHG-1711)

An HO-scale F7A locomotive in freight livery, road number 824, this model recreates GM-EMD’s iconic F-unit for mid-century freight railroading. As part of the F-unit family that helped replace steam on North American mainlines, the design captures the bulldog-nose silhouette and carbody construction that defined the era, making it a versatile centerpiece for period-appropriate freight layouts.

Powered by a Genesis driveline with a five-pole skew-wound motor, precision machined flywheels, and a multi-link drivetrain for smooth, quiet operation, the model rides on RP25 wheels and includes see-through cab windows with a full interior, plus separately applied metal and injection-molded detailing, etched fan grilles, and a detailed fuel system. Body-mounted scale knuckle couplers are Kadee-compatible for reliable coupling, and LED lighting adds realistic cab and marker illumination. The locomotive is DCC-ready with Quick Plug plug-and-play technology and a 21-pin NEM connector, supporting both DC and DCC layouts; some variants offer onboard SoundTraxx Tsunami2 sound with dual speakers for authentic engine, horn, and bell sounds. Roadname- and era-specific options may add features such as different pilots, grilles, and beacons to mirror prototypes. For layout use, it’s designed for minimum 18-inch curves, with 22-inch curves recommended for best performance.
