Rail Track Asset Management and Risk Management

The United States has the most extensive rail network in the world. Freight rail carries over 43% of ton-miles of goods and passenger rail transports millions of passengers annually. Track infrastructure is the most valuable asset to the rail industry. Also, track infrastructure quality is critical for rail safety and risk management. Despite billions of investment in track construction, inspection and maintenance, there is a lack of comprehensive, coherent framework for rail-oriented track asset management. This project develops a customized Concept of Operations (ConOps) of rail track asset management and risk management, built upon an understanding of existing practice, needs and gaps based on survey with one transit railroad. This report presents a comprehensive literature review of broken rails in rail transit based on the resources covering national guidelines and standards, prior publications, and news from social media. It summarizes the potential factors affecting the occurrence of broken rails with engineering heuristics and references in freight rails to help understanding of non-freight rails. The proposed ConOps is then demonstrated in the rail track asset management and risk management and potential applications. Data needs and the roadmap to implement the ConOps in future practice are also identified. Finally, this report concludes with major findings in broken rail reduction benefits and a future work map.
