This vibrant, full sound enhancement to the Kato SD40-2 loco is accomplished with a 100% drop-in decoder. Simply by removing the stock circuit board from the locomotive and dropping in MRC’s 1806 digital decoder.

Equipped with MRC’s world renowned Brilliance™ sound, and dynamic, super-fidelity speaker (permanently mounted on the decoder board), the locomotive truly comes to life, from startup to shutdown.

From the slowest “creep” to “top-end,” experience railroading like never before. MRC’s true, live capture, full fidelity sound includes SD40 prime mover diesel rumbles, actually recorded (railside) from the real diesel locomotive, by MRC’s Sound Engineers. It’s all there… all 28 NMRA available functions, and naturally, MRC provides (16) horns, eightbells, brakes, air releases, pop valves, cooling fans, coupling sounds and more.

Power Pack Users aren’t left out in the cold! DC power pack users can also enjoy the full capability of the 0001806 decoder when coupled to MRC’s unique & exclusive BlackBox (#0001050) control unit.
