N EMD F3B Locomotive Black & Yellow Paragon4 SLSF #5101 (BLI7731)

EMD F3B Locomotive in black and yellow with Paragon4 sound faithfully recreates the classic cab unit used in both freight and passenger service. This SLSF road-numbered model (5101) features authentic paint and lighting with prototypical detailing to capture the era on an HO-scale layout. Equipped with Paragon4 sound and control, it delivers realistic operation on DC and DCC layouts, including the Rolling Thunder audio for added realism.

Inside, a built-in dual-mode decoder with back-EMF supports smooth slow-speed performance, while a robust drive with a die-cast chassis and ABS body provides strong traction. All-wheel pickup, two MicroTrains-compatible couplers, and compatibility with Code 55, 70 and 80 rail ensure reliable pulling on typical layouts, with a minimum 9-inch operating radius. Prototypical details such as Mars Light, number boards, MU doors, and accurately reproduced hatches and handrails enhance authenticity. The model is available as powered A-units with Paragon4 sound and unpowered B-units, or as standalone A or B units with full Paragon4 DC/DCC/Sound for flexible rosters across eight roadnames.
