HO F7B Locomotive AMTK #399 (ATHG19593)

This HO-scale F7B locomotive in Amtrak livery (AMTK #399) is a meticulously detailed, ready-to-run diesel designed for HO layouts. It faithfully captures the F-unit silhouette with a full cab interior and see-through cab windows, plus finely rendered details such as etched metal grills and prototype-specific markings. A heavy die-cast frame provides authentic weight and traction, while LED lighting and accurate Amtrak paint bring the locomotive to life on the layout.

On the rails, the model offers flexible operation and authentic AMTK details. It’s available in DCC-ready form with Quick Plug 21-pin NEM connectors for quick digital setup, and some versions add onboard SoundTraxx Tsunami2 sound with dual speakers for engine, horn, and bell effects. Features include body-mounted scale knuckle couplers compatible with Kadee, RP25 wheel contours for smooth tracking, and a robust drive that delivers steady performance. Prototypical AMTK details such as skirts, icicle breakers on A-units, lifting lugs, and detailed cab and fuel-tank areas round out the presentation, while radii as small as 18 inches (22 inches recommended) keep operation smooth on typical HO layouts.
