HO F7B Locomotive with DCC and Sound MILW #73B (ATHG19704)

HO-scale Milwaukee Road F7B locomotive with DCC and sound, MILW #73B. This cabless B-unit is built for authentic operation on HO layouts, pairing detailed exterior styling with modern model-railroading electronics. An on-board DCC decoder powers SoundTraxx Tsunami2 sound with dual cube speakers for engine, horn, and bell effects that work on both DC and DCC layouts, and the model features see-through cab windows and a full cab interior. A heavy die-cast frame provides solid traction, while etched metal grills, a detailed fuel tank with gauges, and prototype-accurate paint complete the look. Quick Plug plug‑and‑play technology using a 21-pin NEM connector makes decoder upgrades straightforward for DCC enthusiasts.

Milwaukee Road detailing includes roof-mounted oil coolers, modified skirts, winterization hatches, and back-up lights, with A-unit oscillating signal lights in DCC lashups. The locomotive rides on RP25-profile wheels for compatibility with most HO track and uses LED lighting for a realistic appearance. The Genesis driveline, featuring a 5-pole motor, precision flywheels, and a multi-link drivetrain, delivers smooth, quiet operation and strong pulling power. It supports full NMRA-compatible functionality in DCC mode, and CV adjustments allow tailoring of speed, sound, and lighting; a CV chart is included to help with setup for multi-unit lashups.
