ABSTRACT:
A remote train-line braking control system includes first and second air supplies and a first control valve connected in fluid communication between the first air supply and an air pressure controlled diaphragm that controls a fluid pressure supplied to a train-line braking system. A second control valve is connected in fluid communication between the second air supply and the first control valve. The first and second control valves are operable for individually connecting the diaphragm to the first air supply, the second air supply and atmospheric pressure. The diaphragm is responsive to the pressure of air supplied thereto for controlling a fluid pressure supplied to the train-line braking system. When the diaphragm is exposed to atmospheric pressure, the brakes of the train-line braking system are fully applied.
