The TSU-Big Steam is our first web-exclusive decoder available in 3 board formats. This decoder features a true UP Big Boy recording! Previously this sound file was only offered in Athearn factory installed decoders, but now you can get it on our web store. This decoder is available in 3 board formats: TSU-1100, TSU-2200, and TSU-21PNEM8. We will have more web special decoders in the future so stay tuned. You will also get all of the features that you know and love from our Tsunami2 decoder line including: Reactive Dynamic Digital Exhaust, Functioning locomotive and train brakes, injectors, power reverse, and firebox flicker. We also offer a large selection of selectable sound effects including: bells (12), Whistles (90+), couplers, dynamos and more!

These decoders include an optional capacitor or can be wired to a CurrentKeeper (P.N. 810140 or 810160) to maintain performance over dirty track and switches
