Over the last several years the North American railroad industry has seen a determined growth in the area of advanced vehicle health monitoring systems, such as wheel impact load detectors, truck performance detectors, hunting detectors; and more recently, in low hanging air hose detectors, acoustic bearing detectors, and wheel profile measurement systems. The interest in performance-based monitoring is high and growing. Latest developments by Transportation Technology Center, Inc. (TTCI), a wholly owned subsidiary of the Association of American Railroads (AAR), are in the initial stages of deployment and include acoustic roller bearing detectors and truck performance detectors. Together, these detectors and others still in development look to provide railroads and car owners with information on car component performance that can lead to preventive or predictive maintenance. This paper will describe the development and deployment of the Trackside Acoustic Detection System (TADS) and Truck Performance Detector (TPD) by TTCI in North America and internationally.
