This TCRP Synthesis report presents an analysis of the current practices in rail asset management from the industry at large. The findings are based on the results of a survey of 28 heavy- and light-rail transit agencies across the US and three selected case studies. Specifically, this study looks at the rate of occurrence of rail defects, broken rails, and broken rail derailments and how that corresponds to the use of ultrasonic testing by agencies of different sizes and levels of transit system use.
