SoundTraxx Training

Over the past few weeks, we have completed our 2016 SoundTraxx Dealer Training and SoundTraxx Academy. These were two great events that gave us a chance to personally connect with our customers and our dealers. Here we had the opportunity to show off Tsunami2 and its fantastic new features!

Our dealers attended in-depth clinics and presentations about SoundTraxx products including installation and programming of Tsunami2 decoders. Visit our Dealers page for further details and photos!

Our customers also got first-hand experience with Tsunami2 decoder installation and programming. Visit our SoundTraxx Academy page for further details and photos! Below is a video showing the process of installing a Tsunami2 PNP decoder into a diesel locomotive. The video was taken by one of our SoundTraxx Academy participants.
