HO F7A/F7B Locomotives with DCC and Sound - DRGW F7A #5761 F7B #5742 (ATHG-1639)

HO-scale F7A/F7B locomotives with DCC and sound in DRGW livery, presented as a two-unit set for authentic mainline operation on HO layouts. The A-unit is numbered 5761 and the B-unit 5742, designed to run as a matched pair with MU capability. The model includes a built-in DCC decoder and SoundTrax Tsunami2 sound, delivering engine rumble, horn, and bell in both DCC and DC modes, plus LED lighting, directional control, see-through cab windows, and a full cab interior. It also features a detailed fuel tank with fillers and gauges, body-mounted scale knuckle couplers (Kadee compatible), and heavy die-cast construction for traction and pulling power. RP25-contoured wheels and an all-wheel drive system ensure smooth, quiet operation on a wide range of HO track, while Quick Plug plug-and-play technology with a 21-pin NEM connector makes DCC installation straightforward.

DRGW-specific detailing adds to the realism: Phase II F7 styling with freight pilots on the A-units, 48" fan-equipped dynamic brakes, and a nail-type antenna on the A-units. A-units carry 3-chime air horns and the B-unit includes a single-chime hostler/back-up horn. The sound system uses dual cube speakers with separate sound boards for each unit, providing strong low-speed operation and lighting effects such as beacons and prototypically accurate Gyralight. A CV chart is included for tuning and programming a multi-unit lash-up, and the model ships with detailed paint and printing, trainline and MU hoses, lift rings, sanding lines, and other fine details to enhance on-layout realism.
