ABSTRACT:
A railroad air brake system for use on an articulated railroad car having a plurality of platforms and trucks supporting the platforms, has separate air brake subsystems for the trucks supporting the end platforms and an intermediate platform. The subsystem for the intermediate platform includes a control valve connected to the train air supply; an air actuating means for each truck supporting the intermediate platform; a sensor valve having a load sensing arm for each truck supporting the intermediate platform, which sensor valves are commonly connected in parallel to both air actuating means; a proportional valve having an input connected to the control valve and an output commonly connected to both air actuating means and both sensor valves; and a volume reservoir connected the sensor valves and the proportional valve. The application of brake pressure from the control valve to the proportional valve, with an empty load condition at either intermediate platform truck causes the sensor valve associated therewith to cause the proportional valve to reduce the air pressure supplied therefrom to the air actuating means for both trucks supporting the intermediate platform.
