Abstract

AbstractThe California High‐Speed Train Project (CHSTP) is a large‐scale, multi‐discipline infrastructure project to build 800 miles of high‐speed railroad from Los Angeles to San Francisco and beyond. It is the first true high‐speed rail line in the U.S., and as a result faces unique engineering and regulatory challenges. Existing U.S. federal and state safety regulations do not address the full range of safety requirements included in high‐speed rail safety regulations in Europe and Asia. For the CHSTP it was therefore necessary to develop a set of requirements that reflected existing U.S. regulations and incorporated best worldwide high‐speed rail practices. This paper describes how a requirements management database was developed to document, link, manage and understand the requirements, and support the U.S. Federal Rail Administration (FRA) regulatory change process. Expansion of the database highlighted the need for a more robust set of Systems Engineering (SE) processes and tools.
