My understanding of how air brakes work on trains includes that unlike road vehicles on wich the brakes will be off and go on when the driver applies pressure by way of hydraulic or mechanical mechansisms, the brakes will be held off by air pressure and go on when the engineer releases the air. And the system includes that if a hose or connections suffers damage or separation, the loss of air will stop the train. Also, it is common practice to dump the air on a train that is to be parked for a while to prevent unintended movement.
With all of that said, my question is: How do eingineers in switching maneuvers move cars without connecting air hoses?
