EMD F3 A/B Diesel Locomotive A-Unit with Paragon4 Sound and Unpowered B-Unit (BLI9205)

EMD F3 A/B Diesel Locomotive Set with Paragon4 Sound is a two‑unit representation of General Motors' classic F3 cab units, pairing a powered A‑unit with Paragon4 sound with a separate unpowered B‑unit for authentic A‑B operation. Available in prototypically accurate paint schemes and road numbers, including Blue & Aluminum demo versions, these models capture the look and feel of the era while delivering the versatility of display or operation on a layout.

Paragon4 Sound and Control System with Rolling Thunder delivers authentic diesel rumble and horn cues, while an integral dual‑mode decoder with Back EMF supports smooth slow‑speed operation on both DC and DCC layouts. The model features an ABS body riding on a die‑cast chassis for maximum tractive effort, a precision drive mechanism for steady pulling power, and a range of separately applied details such as grab irons, horns, and bells. It also includes two MicroTrains‑compatible couplers and prototypically accurate painting and road numbers to match the chosen scheme.
