Last summer, SoundTraxx had the privilege of recording audio from the famous Big Boy #4014 - the only company to do this before the locomotive’s excursions were halted due to COVID-19.

Athearn Genesis - HO Scale - 4-8-8-4 Big Boy Steam Locomotive - w/DCC & Sound - Heritage Steam Fleet - Union Pacific (UP) #4014 - Race to Promontory - Black/Grey With White Lettering (Era: 2019+) 

Now, in an exclusive decoder, we are introducing the actual sound recordings of the Big Boy, featured in our new Tsunami2 for Big Steam!  This decoder will be available in TSU-1100, TSU-2200 and the TSU-21PNEM8 decoder formats.  Never before have the authentic sounds of the Big Boy been available to be heard on model rails!  Now, they can!!

 The Tsunami2 for Big Steam (TSU-BIGSTEAM) decoders will be available in these three formats for purchase

This decoder will be loaded with many of the popular sounds you can find on the Tsunami2 for Steam-2.  The difference is that because of memory chip space limitations, we have replaced a few of the standard sounds that would be more likely associated with small engines with ones that are unique to the Big Boy. 

This includes recordings of the whistle in both a yard and road mix, the Big Boy brass bell, the exhaust chuff, brakes, feedwater system and more!  These are taken from the same sounds that have been loaded into the new Big Boy model from Athearn making a perfect opportunity for you to upgrade your Big Boy Locomotives!
