Abstract
A system for monitoring usage of rail car brake equipment and determining whether the actual lifespan of the brake equipment is shorter than an expected lifespan had the brake equipment been used under normal or constant parameters. The system includes a sensor for collecting and outputting data indicating how the brake equipment has been actually used. A controller is programmed to receive the data regarding how the brake system component has been used and to calculate whether the brake system component has an estimated lifespan that is shorter than the expected lifespan. The sensor may comprise an ambient temperature sensor, a flow sensor that determines the air used by the braking system that includes the brake system component, and/or a pressure sensor that can determines how frequently and in what manner the brake system has been used.
