Many of the newer NYC trains, I am told, are more complicated - an emergency lever pull (someone caught in the doors) should hard-brake the train. If it's travelled more than 1000 feet, it is assumed the train is already in the tunnel, and the lever just signals the conductor, who presumably will radio for help and tell the operator to hold at the next station. I guess this implies that there's a computer inline.

The tripcocks, I hope, are still connected directly to the brakes.
