EMD GP40 Diesel Locomotive B&O #3688 with Dynamic Brakes N Scale (BAC63571)

This N-scale model recreates the EMD GP40 diesel locomotive in Baltimore & Ohio livery, number 3688, equipped with dynamic brakes. It captures the late-1960s GP40 profile—a four-axle workhorse that was easy to maintain and widely used for freight and yard duties—making it a credible addition to any rail layout.

Authentic detailing recreates the GP40’s distinctive long hood and the familiar radiator fan layout, delivering a convincing silhouette. The dynamic braking capability adds realism to slow-speed maneuvers and descents, while the compact N-scale form keeps this locomotive at home on tight layouts and busy yard scenes.
