Abstract
A brake control system for a railway vehicle having separately operated independent and automatic brake controls for controlling brake pressure via a double check valve and a multi-piston relay valve, wherein an adjustable regulating valve is set to exhaust the independent brake control pressure acting on one piston of the multi-piston relay valve when the relay valve delivery pressure (brake cylinder pressure) exceeds a predetermined value, to thereby limit the maximum brake cylinder pressure attainable from the combined independent and automatic brake controls unless the automatic brake pressure exceeds that predetermined value.
