## Highlights

This testimony discusses the potential viability of high speed rail in the United States. Federal and other decision makers have had a renewed interest in how high speed rail might fit into the national transportation system and address increasing mobility constraints on highways and at airports due to congestion. This testimony is based on our report issued March 19, 2009, entitled High Speed Passenger Rail: Future Development Will Depend on Addressing Financial and Other Challenges and Establishing a Clear Federal Role. In preparing the report, we reviewed federal legislation; interviewed federal, state, local, and private sector officials, as well as U.S. project sponsors; and reviewed high speed rail development in France, Japan, and Spain. More detailed information on our scope and methodology appears in the March 19, 2009, report. We conducted our work in accordance with generally accepted government auditing standards. This statement focuses on (1) the factors affecting the economic viability of high speed rail projects, including difficulties in determining the economic viability of proposed projects; (2) the challenges in developing and financing high speed rail systems; and (3) the federal role in the potential development of U.S. high speed rail systems.
