I decided to take a look at the simulator today. Here's a basic description of the control stand. There is a single master controller, similar to that of the M7 and M8. Power is applied by moving the controller away from the operator, and brakes are applied by moving the controller towards the operator. There is no emergency position on the controller. Instead, there is a red emergency stop button below the controller. There are also two green door enable buttons, one for each side, and a yellow horn button at the far top left corner. Sounds are heard through a pair of headphones.
