A continuously variable load responsive brake pressure control valve controls the amount of brake pipe pressure for a railway vehicle. The system also includes means for isolating the load sensing means from transient inputs caused by normal vehicle motion. A spring loaded isolator coupled with a matched hydraulic cylinder isolate wheel truck deflections with respect to the car body, preventing erroneous inputs to the load sensor of the variable load braking system so as to provide more accurate brake cylinder pressure according to vehicle load weight. The variable load limiting valve is continuously operable between an empty vehicle condition and a fully loaded vehicle condition and assures a minimum braking pressure, while also helping prevent sticking of the brakes.
