@Theme Park I am not 100 percent share what all the controls do but the key switch to the far right switches the ride from operation to maintenance.
The green button just bellow the ear muff sticker Dispatches the train.
The other key switch turns the controls on and off.
The orange button turns the lights off and starts the sound effects.
The big red button at the top is the e-stop.
And the red plaque says If dispatching car between 7:45 and 9:00 am please confirm with tiger island via two way radio prior to dispatch.
i hope this helped
