SoundTraxx has been providing Digital Sound Decoders to Walthers since 2011. If you have purchased a quality Walthers Proto or Mainline series locomotive equipped with SoundTraxx Digital Sound Technology, congratulations! Each sound-equipped locomotive comes with multiple horns to allow you to customize the locomotive to your personal tastes or more closely match your prototype railroad. Proto sound-equipped locomotives include all of the amazing features found in aftermarket Tsunami decoders, including the ability to set up manual notching, a built in 7 band equalizer, built in reverb, all 15 hyperlight lighting effects, and advanced motor control.

For a complete breakdown of all of the CVs and Tsunami capabilities please reference the Tsunami Diesel User’s guide and Tsunami Technical Reference on our Documentation page or visit
