HO F9A / F9B Locomotive Set, Louisville & Nashville Era (ATHG-1713)

The HO-scale F9A/F9B Locomotive Set is a faithful two‑unit representation of the EMD F-unit diesel locomotives, offered in Louisville & Nashville era and Freight LN road numbers. This A‑B pair features a detailed die‑cast chassis, see‑through cab windows with a full interior, and a wealth of separately applied parts such as coupler cut levers, windshield wipers, wire grab irons, trainline and MU hoses, plus lit signal lights or beacons where equipped. The locomotives ride on RP25 wheels, use body‑mounted scale McHenry knuckle couplers (Kadee‑compatible), and deliver smooth, quiet operation with an all‑wheel drive and a robust 5‑pole skew‑wound motor. DCC‑ready Quick Plug technology with a 21‑pin NEM connector makes digital setup straightforward, while LED lighting adds to the realism of prototypical operation.

Beyond looks, the set reflects prototype accuracy—from final assembly in GM‑EMD facilities to period paint schemes and road‑name details. It’s built for HO layouts with features that suit mainline operation, including a heavy die‑cast frame and precise gearing for traction. Some versions offer onboard DCC with SoundTraxx Tsunami2 sound and dual speakers for authentic engine, horn, and bell effects, working in both DC and DCC modes. The models invite multiple‑unit lashups, adjustable lighting, and a ready platform for weathering to recreate the “In Service” grime of real locomotives, while packaging helps keep the model secure when stored or transported.
