ABSTRACT: The development of both incremental and dedicated high-speed rail lines in the United States poses a number of questions. Despite nearly 50 years of international experience in planning, designing, building and operating high-speed passenger infrastructure and rolling stock, there is a range of problems partially or completely unique to North America. Successful development of expanded higher speed, and new, very high-speed rail, will require careful analysis and, in many cases, research to develop satisfactory solutions. The questions involve a range of engineering, operational, economic, and institutional aspects. This report introduces various technical challenges related to shared high-speed passenger and freight rail corridors, describes an effort to prioritize the challenges, and presents an in-depth literature review of the high-priority challenges to identify existing research and future research needs.
