HO F7B Locomotive with DCC and Sound, Freight ATSF #266A (ATHG-1729)

HO-scale F7B locomotive with DCC and sound in Santa Fe Freight livery, road number 266A. This highly detailed model is built for realistic operation on model railroads, pairing a DCC decoder with Tsunami2 sound for authentic engine, horn, and bell effects and smooth, controlled motion. A Genesis driveline with a 5-pole motor and all-wheel drive delivers steady pulling power, while dual speakers and directional LED lighting add depth and realism. DCC-ready Quick Plug plug-and-play technology with a 21-pin NEM connector makes setup quick and straightforward for layouts of any size.

Inside, see-through cab windows reveal a full interior, with etched metal fan grilles and realistic fuel tanks. It rides on RP25-wheel contours and uses body-mounted McHenry scale knuckle couplers (Kadee-compatible), all supported by a heavy die-cast frame for enhanced traction. The model is designed for an 18-inch minimum radius (22-inch recommended) and finished in prototype-accurate paint. Sound-equipped versions feature onboard Tsunami2 sound with two speakers and operate in both DC and DCC, with NMRA-compatible functions in DCC and CV-based tuning; a CV chart is included for reference. A primed-for-grime variant is also available, providing a ready base for weathering to recreate in-service locomotives with faded colors and realistic grime.
