Your train is no longer limited to locomotive sounds! This 16-bit, universal-style Digital Sound Decoder is the only DCC decoder to replicate railcar sounds and lighting effects. It includes selections for livestock sounds, airhorns, whistles, bells, and interior and exterior lighting effects for passenger cars, cab cars, and cabooses.


Dimensions: 48 x 13.5 x 9mm
Max Function Current: 100mA (each output)
Audio Amplifier: 1 Watts, 8-Ohm Load


CurrentKeeper Plug: Yes
Function Outputs: 4
DCC Track Voltage: 7.5V - 22V

These decoders are easy to install in N to G scales. 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 optional use with the SoundTraxx CurrentKeeper™ to maintain sounds and lights during momentary power losses due to finicky wheel pickups and not-so-perfect track.
