HO F7A / F7B Locomotive Set with DCC & Sound (MKT #72C, #75F) (ATHG-1720)

HO-scale F7A/F7B Locomotive Set with DCC & Sound recreates General Motors' classic F-unit diesels for HO layouts, delivering authentic period detail and modern control in a ready-to-run two-unit package. This A/B pair is equipped with onboard DCC decoders and SoundTraxx Tsunami2 sound, with dual cube speakers to deliver realistic engine, horn, and bell audio, and it operates on both DC and DCC layouts.

Designed for HO layouts, the model features a heavy die-cast frame for traction, LED lighting, a see-through cab with interior, and finely detailed exterior details such as etched grills and separately applied parts. It uses body-mounted scale knuckle couplers that are Kadee-compatible, and a DCC-ready Quick Plug 21-pin NEM connector makes upgrading easy; RP25 wheels help it track smoothly on common HO track, with minimum radius 18 inches (22 inches recommended). In DC mode some functions are limited, while in DCC mode all functions are NMRA-compatible, and the set supports MU lashups for realistic, prototypical operation.
