HO F7A Amtrak #100 Locomotive (RND3254)

An HO-scale F7A Amtrak #100 locomotive, a ready-to-run diesel model built for HO layouts. It features a 5-pole motor with precision-machined flywheels and a multi-link drive for smooth, reliable operation, plus all-wheel drive with precision gears for quiet, steady power. The heavy die-cast frame adds traction and pulling ability, while a clear cab window, separately applied horns, McHenry operating scale knuckles, and a DCC-ready 21-pin plug boost realism and upgrade options. Machined RP25 wheels ensure dependable tracking on HO track, and the highly detailed injection-molded body is painted and decorated for authentic appearance out of the box. It’s ready to run on HO layouts with an 18-inch minimum radius and performs best on 22-inch-radius curves.

Prototype context and design: The F7 was a 1,500-horsepower diesel-electric locomotive introduced by EMD in the late 1940s and widely used for decades, valued for durability and versatility. This model captures that heritage with a robust die-cast chassis and faithfully detailed body that suits both passenger and freight work on an HO layout. With a DCC-ready interface and ready-to-run convenience, it’s easy to upgrade for digital control or sound, making this F7A a versatile centerpiece for any HO railroad roster.
