For the first time ever, Kato is producing a Sound Card for Passenger Car On Board Sounds! With this card you can ride along in a North American passenger car as the smooth hum of the rails and the occasional passing train paint the scene of your journey. This card features the most functions of any of our sound cards with each button having multiple responses whether the train is moving or stationary.The sound card is equipped with firmware update programs that add the following functions to the Soundbox- Emergency Stopo Adds an emergency stop function to the “Eject Button” that causes a train in motion to stop when pressed- Direct Control Mode selectiono Enables a quicker response from the locomotive with throttle adjustments.- Saved Control Mode Selectiono Automatically saves whichever operation mode is selected to be the default setting when the unit is powered on.
