HO F7A / F7B Locomotive Set Freight MKT #72C #75F (ATHG-1706)

An HO-scale F7A/F7B Locomotive Set in the MKT Freight livery, numbers 72C and 75F, brings the classic GM EMD F-unit era to life on a modern HO layout. This pair of A and B units recreates the distinctive bulldog-nose and carbody design that defined early diesel freight power, making it ideal for realistic mainline operations. Built on a heavy die-cast frame with a Genesis drivetrain, the models deliver smooth, quiet performance thanks to a 5-pole skew-wound motor, precision flywheels, and a multi-link drive. Realistic detailing includes see-through cab windows with a full interior, separately applied metal parts, etched grills, a detailed fuel system, and directional LED lighting. They’re designed for easy digital control with Quick Plug plug-and-play technology and a 21-pin NEM connector, and they roll on RP25-profile wheels for reliable performance on common HO track.

Prototype fidelity extends to road-number specific features, including large roof-mounted cooling coils, standard headlights, and period-appropriate grille styles to match the MKT scheme. Sound-ready versions can add onboard DCC sound (SoundTraxx Tsunami2) with dual speakers that operate in both DC and DCC, with CVs to tailor engine, horn, and bell sounds. The models are also primed for weathering, providing a ready starting point for grime and rust to reproduce an active-service look. With authentic detailing, robust construction, and flexible control options, this HO F7A/F7B set makes a compelling centerpiece for any freight-era layout.
