ABSTRACT: A prototype crack detection system for railroad wheels has been developed by the National Institute of Standards and Technology (NIST) for the Federal Railroad Administration (FRA). The system is designed to detect the presence of thermal cracks in railroad wheels as they pass by an inspection point. The Association of American Railroads (AAR) has completed testing of the prototype wheel crack detector at the Transportation Test Center in Pueblo, CO. The response of the detector was measured for 20 wheel sets that were operated over the detector at speeds of 5, 10, and 20 mph.
