Abstract
An electro pneumatic system is provided for simultaneously braking a plurality of railway cars in a train. A relay valve in each car is connected between the source of air braking pressure and the brake cylinders and is responsive to the amount of air pressure within an independent air reservoir in each of the cars to apply or release the brakes. Electrical means are selectively operated to control the amount of air pressure in each independent air reservoir.
