HO F7A/F7B Locomotives with DCC and Sound (ATHG-1636)

HO Scale F7A and F7B locomotives with DCC and sound bring the classic EMD F-unit lineage to HO layouts, combining detailed exterior with modern operating features in a two-unit A/B configuration. These models reproduce the look and character of early diesel power, including see-through cab windows, full cab interior, LED lighting, and a heavy die-cast frame that adds presence and traction on the rails.

Inside, an onboard DCC decoder with SoundTraxx Tsunami2 provides authentic engine, horn, and bell sounds, while dual cube speakers deliver clear, balanced audio. The locomotives run on both DC and DCC (some functions are limited in DC), and use Quick Plug plug-and-play technology with a 21-pin NEM connector for easy decoder upgrades. Prototypical details carry through with body-mounted McHenry knuckle couplers, RP25-contoured wheels for broad track compatibility, all-wheel drive for smooth operation, and a heavy frame that translates to steady pulling power on standard HO curves.
