EMD F3A DLW 663 with Paragon4 Sound Diesel Locomotive (BLI9207)

HO-scale EMD F3A Diesel Locomotive with Paragon4 Sound in DLW 663, a faithful reproduction of General Motors’ EMD F3 cab unit from the late 1940s. This model brings the century-old locomotive’s freight- and passenger-service heritage to your layout, featuring prototypical paint schemes and road numbers across multiple railroads. Available as powered A-units with Paragon4 Sound paired to unpowered B-units, or as standalone A or B units, all with full Paragon4 sound and DC/DCC compatibility for flexible operation.

Paragon4 Sound with Rolling Thunder drives authentic sound and performance, while a dual-mode decoder with Back EMF ensures smooth slow-speed operation in both DC and DCC. The drive is engineered for strong pulling power and steady, natural motion, with all-wheel electrical pickup, a die-cast chassis, and an ABS body for durability and traction. Along with numerous separately applied details, prototypical lighting, and two MicroTrains-compatible couplers, the model runs on Code 55, 70, and 80 rails and requires only a 9-inch minimum radius—making it a versatile centerpiece for serious HO layouts.
