PC M8 Emus On Northeast Corridor Metro-north: New York - Stamford Route Add-on

I am running the M8 train in Free Roam mode. I started at Grand Central and ended at the car wash at Stamford. I changed ends and tried to run the train but I couldn't do it. Before leaving the cab at one end, I set reverser to key out, set controller to emergency, and took the master key out. After switching ends and got into the cab. I put the master key in, set brakes to max, wait for air brakes to charge, set reverser to forward, and tried to move the train but nothing happened. Is this because I set the brakes to emergency in the other cab? The M8 train can run from overhead wires or from third rail. The control panel where I switch power between overhead wires and third rail confused me. The switch can be set to third rail, panto up, panto down, and emergency panto down, Below the switch is a button that I'm supposed to press after setting panto up. How can I get the train to run?

 

There is a bug where the brakes in the unit where you were controlling the first time get stuck on when you change ends. If you apply more power, you can move.

 

I tried the cab-changing tutorial that use different EMUs and it worked. Are there any other EMUs that work on the route?
