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.

This synthesis report assembles and shares the current state of practice for the implementation of the 1990 ADA regulation in transit systems. It documents examples from six transit systems as they make modifications to support individuals with disabilities and meet the expectations of the legislation. It also mentions future research needs in this area.

This report presents an essential component of an airport's risk management data process: collecting and sharing operations and safety data. Such data helps airports monitor their performance and benchmark against the industry. To aid airports in this endeavor, this report identifies best practices and data sources for collecting such data. It also explains some of the challenges associated with the process and outlines a plan for a future national database.
