1. A train brake diagnostic system, comprising:
- a plurality of transducers for outputting status data of a single rail car, wherein said plurality of transducers include a brake pipe transducer connected to a brake pipe of the single rail car and at least a first brake cylinder transducer connected to an input of an empty load device of the single rail car and a second brake cylinder transducer connected to an output of the empty load device of the single rail car;
an accelerometer providing movement data of the single rail car;
a global positioning system providing time and location data of the single rail car;
a processor interconnected to the plurality of transducers, wherein said processor is programmed to receive and store the status data received from the plurality of transducers, the accelerometer, and the global position system over a predetermined period of time, to compare the data received from the plurality of transducers against a predetermined performance standard, to determine whether a fault has occurred in the single rail car based on the comparison, and to prepare an electronic report if a fault has occurred that includes the status data received from the plurality of transducers as well as the movement data received from the accelerometer and the time and location data received from the global positioning system for a predetermined time period prior to the fault.

Abstract
A brake valve diagnostic and reporting system for a pneumatic only brake valve on a rail car which includes a brake pipe transducer for measuring brake pipe pressure; and a brake cylinder transducer for measuring brake cylinder pressure. A processor receives measurements from the transducers, compares the measurements against stored brake performance profiles, determines brake status from the comparison and prepares an event report for preselected brake statuses. A wireless transmitter connected to the processor transmits the report. An energy storage device powers the processor and transmitter.
