Abstract
An electro-pneumatic brake control system for a railroad car including application and release solenoid valves having a fail-safe configuration in which full emergency brake pressure is delivered in the event of a power loss due to a train break-in-two for example. The present invention discloses a pressure limiting valve for the purpose of limiting the maximum pressure capable of being delivered in accordance with the existing car load weight sensed by an electric load sensor at the time a power loss is experienced.
