Friction brake interface health check system for multiple-axle railway vehicles
 A friction brake interface health check system for dynamically diagnosing and monitoring the operational status of a plurality of input signals by using a pattern fault recognition and an intelligent diagnostic matrix which is generated by brake level demand, power/brake trainline, electric brake feedback and electric brake rate request modules to control an interface health determination fault monitor module which determines which errors are to be reported to the event interface file, the RAM fault log and which are displayed on a seven (7) segment display.
