Bachmann Industries

SoundTraxx has been providing Tsunami Digital Sound Decoders to Bachmann Trains since 2006.  If you have purchased a quality Bachmann® Spectrum® locomotive equipped with SoundTraxx Tsunami Digital Sound Technology, congratulations! This state-of-the-art sound decoder will provide all the pleasures of high quality, digital onboard sound and the benefits of today’s DCC technology. If you aren’t sure, look for the DCC Sound On Board logo on your locomotive’s box.


Each Bachmann sound-equipped locomotive comes with multiple whistles to allow you to customize the locomotive to your personal tastes or more closely match your prototype railroad. Bachmann sound-equipped locomotives include most of the amazing features found in all aftermarket Tsunami decoders, including 16-bit digital sound and advanced motor controls. Listed below are the locomotive models that currently are or will be shipped with Tsunami Digital Sound Decoders installed.  Select your model from the list to link to a quick reference document specific to that engine. For a complete breakdown of all of the CVs and Tsunami’s capabilities please reference the Bachmann Quick Start Guide, User’s Guide and Technical reference on our website or visit www.bachmanntrains.com.
