EMD F7A Cotton Belt 931 Black Widow N Scale Locomotive (BLI9251)

The EMD F7A Cotton Belt 931 Black Widow N-scale locomotive is a highly detailed diesel model built for serious hobbyists and layout operators. This Paragon4-equipped unit runs on DC or DCC and features authentic road-numbering and the Cotton Belt 931 Black Widow paint scheme to capture the era's look, sound, and operation.

Designed with an ABS body and die-cast chassis for durability and solid tractive power, it offers reliable performance with all-wheel electrical pickup. The model includes two MicroTrains-compatible couplers and a range of prototypical detailing and lighting; it is available as a powered A-unit with Paragon4 Sound paired with an unpowered B-unit, or as standalone A or B units with full Paragon4 DC/DCC/Sound. It supports operation on Code 55, 70, and 80 rails and navigates curves with a minimum 9-inch radius, making it versatile for modern N-scale layouts.
