DCC decoders convert a standard DC locomotive into a digitally controlled, addressable locomotive — and on most modern models you can also add prototypical sound, prime-mover audio, dynamic braking, and lighting effects. Our Decoders collection covers motor-only decoders, sound decoders, and the plug-and-play form factors that make installation easier.
We stock heavily from SoundTraxx (the Tsunami2 line — TSU-1100 1-amp, TSU-2200 2-amp, TSU-4400 4-amp, TSU-21PNEM8 8-function 21-pin, and TSU-PNP8 drop-in 8-pin for EMD, Alco and Baldwin prototypes), Digitrax (Series 7 SoundFX decoders for HO and N, including the SDXN147PS N-scale plug-and-play and SDYH168DST HO stereo decoder), and ESU LokSound (industry-leading sound quality, common in factory-equipped Rapido and ScaleTrains releases).
For HO, the typical decoder is a 21-pin plug-in if the locomotive is decoder-ready, or a hardwire micro decoder for older models. For N, micro form factors and 8-pin plug-ins dominate. Need a controller to run these decoders? See our Controllers and Digitrax / NCE collections. Ships from Oakville, Ontario. Free shipping on orders over $250.
