N EMD SD40-2 BNSF 1686 Diesel Locomotive with Paragon4 Sound (BLI9463)

An EMD SD40-2 diesel locomotive in BNSF 1686 livery with patch, equipped with Paragon4 Sound and Control System featuring Rolling Thunder, delivering authentic locomotive sound and responsive performance for DC and DCC layouts.

With an ABS body and die-cast chassis for durability and strong tractive effort, the model uses a precision drive and all-wheel electrical pickup for smooth, realistic movement. A dual-mode decoder with back-EMF provides reliable slow-speed operation on both DC and DCC layouts, while separately applied details—handrails, grab irons, horns, bells, and antennas—plus prototypical lighting and authentic EMD SD40-2 sounds boost realism. Two MicroTrains-compatible couplers are included, and the model runs on Code 55, 70, and 80 rails with a 9-inch minimum operating radius.
