HO F3A/F3B Locomotives with DCC and Sound - Passenger GN F3A #260A, F3B #260B (ATHG-1634)

HO-scale F3A and F3B locomotives in the Great Northern passenger livery, GN 260A and GN 260B, with DCC and Tsunami2 sound. These F-unit diesels bring authentic early‑generation diesel styling to HO layouts, pairing prototypical detailing with modern control and onboard sound for a convincing passenger‑service model.

Under the hood, a Genesis driveline with a five‑pole skew‑wound motor drives a heavy die‑cast frame for solid traction and smooth operation. Features include LED lighting, see‑through cab windows with a full cab interior, and body‑mounted McHenry knuckle couplers (Kadee‑compatible) for realistic coupling. The DCC‑ready design uses Quick Plug plug‑and‑play on a 21‑pin NEM connector, and sound-equipped versions use dual cube speakers to deliver Tsunami2 engine, horn, and bell sounds; some functions may be limited in DC. Minimum radius is 18 inches (22 inches recommended), with RP25 wheels for compatibility across popular HO brands. Roadnames offered include GN Great Northern, CS, and DRGW, each with prototype‑specific details such as pilots and dynamic brakes to match the chosen roadname.
