This report addresses the public benefits and investment needs of intercity passenger rail transportation. AASHTO has published an investment needs report for highways and transit, and intends to publish a report on freight rail investment needs. Cost estimates for intercity passenger rail investment presented in this report were developed independently from those contained in the freight rail report. In combination, these reports provide a complete picture of the benefits of the various surface transportation modes to the U.S. and the value to be realized by both the traveling public and shippers through strategic investments.
