Tsunami Digital Sound Car

Now your train is no longer limited to locomotive sounds! The 16-bit Tsunami SoundCar Digital Sound Decoder™ is the only DCC decoder to replicate railcar sounds, such as the clickety-clack, flange squeal, flat spots, generator, brake cylinders, and glad hand release. It also includes a selection of user-adjustable horns, bells and whistles for cab cars and cabooses. For even more realism, the decoder has four Hyperlight lighting outputs for interior and exterior lights.

These universal-style decoders measure 47mm x 14mm x 8.5mm and are easy to install in N to G scales. They work with any 8-ohm speaker.  For the optimal experience, use a SoundCar decoder in every third or fourth car in a consist.

The SoundCar also includes a 2-pin plug for optionally using the SoundTraxx CurrentKeeper™ to maintain sounds and lights during momentary power losses due to finicky wheel pickups and not-so-perfect track. 


3 pack Current Keeper

This 40mm x 6mm x 11mm DCC Accessory maintains power to the decoder for up to 10 seconds during electrical interruptions.
