Model Railroad Sound Systems

SoundTraxx brings new dimensions in digital sound technology to your model railroad. Regardless of your scale or prototype, we have a sound system for you! We manufacture all of our Digital Sound Decoders in the USA, right here in Durango, Colorado. Our professional sound engineers record and edit our sound files and test our decoders multiple times before we ship to ensure top quality.

Just what the heck is a ‘blower’? George will take a closer look at a steam loco, how it works and how Tsunami2 helps simulate the blower and many of the over 50 sound effects built in to the Tsunami2. Join us as we walk you through the steps to set up your Tsunami2 Steam decoder and use these features.

WHY CHOOSE SOUNDTRAXX?

We've been designing and manufacturing the latest innovations in model railroad electronics since 1990. Our product lines offer a variety of solutions to help you add new dimensions to your railroad with sound, lighting, and other DCC technologies.

"Thank You George for your time spent giving my Wife and I a tour of the SoundTraxx facility today. It’s not often this day and age when one finds a company such as SoundTraxx that makes the time to spend with a customer as you did. The ideas and insight you gave me is invaluable and very much appreciated. Thank You again George."

“I sure do appreciate all of the help. I have 4 more old DC locos and they will all host Soundtraxx decoders. Your knowledge and sales support sets you apart from the rest.”

"Dear sirs just thought I’d run a couple of my thoughts your way. I purchased a Atheran Genesis GP38-2 a while back it came with the new tsunami2 decoder. I have serval Genesis locomotives but all of them have older tsunami decoders. I must say While I always thought you had the best sound they lacked in motor performance.

NO MORE tsunami2 has as good if not better motor control than their competitor. I love the slow speed right out of the box and the {for lack of better words} full throttle features while never losing control of your loco. It is top notch, not to mention the new brake options /independent/train and dyno... Kudos for making the Tsunami2 it’s great oh buy the way {don’t hear it much anymore} proudly made in the USA."
