HO F7A Locomotive MEC #686 (RND3332)

HO Scale F7A Locomotive MEC #686 — a ready-to-run HO model of the EMD F7A diesel in Maine Central livery, road number 686. This Phase I Early variant recreates the classic mid‑century power with faithful detailing and dependable operation for HO layouts.

Designed for DCC enthusiasts, it features 21-pin DCC compatibility, a heavy die-cast frame and all‑wheel drive for smooth, quiet pulling. Refinements include revised body‑to‑chassis mounting, a rear‑coupler box with two mounting locations, and flush cab and rear window glass. Extras such as separately applied horns, McHenry scale‑knuckle couplers, RP25 wheel contours, and a 5‑pole motor with flywheels deliver reliable power and prototypical performance, while the model arrives fully assembled, pre‑painted, and ready to run on layouts with an 18" minimum radius.
