Service 222D-02, 1938 stock On acceleration out of station, regular complete cut of loco sound Ryzen 7/RTX 3060/RailDriver
This could be several reasons. One reason is that you're not on fourth rail so you won't get power to the train, so no sound no matter what notch you are in. Or is the train just silent when you are sitting down/no runs sounds. This is just a poor implementation of sound rivet have done.
