Model railroad manufacturer and distributor Wm. K. Walthers Inc. has announced a new partnership with SoundTraxx for the use of Tsunami decoders in Proto 2000 models with sound and DCC.  Walthers’ recently announced HO scale Pennsylvania E8A and E7B units for the Broadway Limited, and an updated run of SD45s, will be the first units with the sound system.  

Decoders for these (and future releases) will be custom-made to fit Walthers circuit boards, and include the full range of Tsunami operating, lighting and sound features. Using the extensive SoundTraxx library of recordings made live and on location, sounds will match prime movers, bells, air horns and other road-specific equipment.

Walthers will continue to provide warranty repairs and support for earlier Proto models equipped with QSI sound and DCC systems.
