EMD F3 A/B ACL 339/339B Diesel Locomotive Set (BLI9200)

An ACL purple-and-silver EMD F3 A/B diesel locomotive set, a faithful model of General Motors’ postwar F3 cab units designed for authentic railroad realism. This two‑unit package includes a powered A‑unit with Paragon4 Sound and a dual‑mode DC/DCC decoder, paired with an unpowered B‑unit in the same livery, carrying ACL road numbers 339 and 339B to match the prototype roster.

Designed for detailed realism and versatile operation, the model features road-specific detailing such as Mars Light where prototypical, correctly placed numberboards and horns, water and sand fill locations, dynamic braking, cooling fans, and a winterization hatch, plus multiple MU doors and grab irons. The A‑unit’s Paragon4 Sound with Rolling Thunder delivers authentic engine sounds and control, supported by all‑wheel electrical pickup, a die‑cast chassis, and a durable ABS body for strong traction. Ready for DC or DCC layouts, it includes prototypical lighting and separately applied details, MicroTrains‑compatible couplers, and compatibility with Code 55, 70, and 80 rails and a 9‑inch minimum operating radius.
