Abstract
An intelligent, on-board, train brake safety monitoring and fault action system is disclosed. The system compares measured dynamic train brake performance using on-board train control system, such as a LEADER® system. Using the measured dynamic train brake performance, the brake monitoring system can determine whether the train is capable of stopping within a particular required distance, such as a stop distance set by a positive train control system in which the train is participating. The ongoing ability to meet external braking criteria, such as compliance with positive train control stop distances, may be used to extend the interval between any mandated train brake inspections and tests.
