HO F7A Locomotive MEC #681 (RND3331)

An HO-scale F7A diesel locomotive in MEC livery with road number 681, this model faithfully captures the classic EMD F7A profile for HO layouts. Ready to run out of the box, it brings authentic mid‑century power to both freight and passenger scenes on a model railroad.

Inside, updated tooling mirrors the Phase I Early F7A and accommodates 21-pin DCC decoders, while a heavy die-cast frame provides solid weight for smooth operation. The chassis-to-body mounting is refined for easier maintenance and kit-bashing into de-skirted versions, and a rear coupler box offers two positions for close‑coupling or tight-curvature running. Realistic details include flush cab glass, separately applied horns, and McHenry scale knuckle couplers, plus RP25 wheels and an all‑wheel‑drive drivetrain powered by a 5‑pole motor for quiet, reliable performance. It arrives fully assembled, painted, and decorated, ready to trek across layouts with minimum 18-inch radius curves.
