Unitrack's control equipment series, Sound Box, adds realistic sound to your model railroad. It is a good item that you can enjoy the realistic "sound" in the driver's seat and easily become a "driver", and rediscover the "healing" and "joy of driving" by running a model railroad.
By adding a sound card to the sound box (sold separately), you can drive with a fusion of sound and model railroad, and enjoy driving the vehicle.

The first lineup of resistance-controlled trains in the sound card series. Not only the sound of the JNR standard MT54 motor, but also the resistor blower sound and ATS-S warning sound unique to JNR vehicles are reproduced. The 115 series and 117 series C2000 type compressor sounds and the operating sound of the door engine are also reproduced.
