HO EMD F3B Locomotive CBQ 9961B with Paragon4 Sound (BLI8171)

HO-scale EMD F3B diesel locomotive in CB&Q livery, offered in two finishes—the aluminum-black stripe scheme and the standard CB&Q paint—and equipped with Paragon4 sound for authentic diesel operation on a model railroad. Road numbers are prototypically accurate to match CB&Q equipment.

Built for realistic HO-scale layouts, the F3B carries road-specific detailing and lighting to reflect prototype variations, including multiple pilot configurations and nose-door options. It's available as A-B sets with powered A-units (featuring Paragon4 sound) and unpowered B-units, and also as single A or B units with the full Paragon4 DC/DCC/Sound system to accommodate both DC layouts and DCC-equipped layouts.
