HO F3A/F3B Locomotives Great Northern Railroad Set (ATHG-1629)

HO-scale F3A/F3B Locomotives — Great Northern Passenger Set bring authentic F-unit power to HO layouts. This matched A‑B pair reproduces the Great Northern’s passenger locomotives, complete with see‑through cab windows, a full interior, prototypical detailing, and GN livery, making it ideal for running GN passenger trains or adding a realistic Great Northern presence to a layout.

Powered by a Genesis driveline with a 5‑pole skew‑wound motor and a heavy die‑cast frame, these units offer smooth, quiet operation and solid pulling power with all‑wheel electrical pickup. They ride on RP25‑contoured wheels and are DCC‑ready with a Quick Plug 21‑pin NEM connector and body‑mounted scale knuckle couplers, while detailed features include photo‑etched metal parts, etched fan grilles, see‑through cabs and interior fittings, and LED lighting for realistic signaling. Sound‑equipped variants add onboard DCC decoders with SoundTraxx Tsunami2, dual speakers in both A and B units, and MU/CV customization, with some functions limited in DC operation. Minimum radius 18 inches; recommended 22 inches.
