Railroad Bridges and Tunnels: Federal Role in Providing Safety Oversight and Freight Infrastructure Investment Could Be Better Targeted

摘要

Freight railroads account for over 40 percent (by weight) of the nation's freight on a privately owned network that was largely built almost 100 years ago and includes over 76,000 railroad bridges and over 800 tunnels. As requested, GAO provides information on this infrastructure, addressing (1) the information that is available on the condition of railroad bridges and tunnels and on their contribution to railroad congestion, (2) the federal role in overseeing railroad bridge and tunnel safety, (3) the current uses of public funds for railroad infrastructure investments, and (4) criteria and a framework for guiding any future federal role in freight infrastructure investments. GAO reviewed federal bridge safety guidelines and reports, conducted site visits, and interviewed federal, state, railroad, and other officials. Little information is publicly available on the condition of railroad bridges and tunnels and on their contribution to congestion because the railroads consider this information proprietary and share it with the federal government selectively. GAO has identified critical questions that can serve as criteria for reexamining the federal role in freight investments--including railroad bridge and tunnel investments--and a framework for implementing that role that includes identifying national goals, clarifying stakeholder roles, and ensuring that revenue sources and funding mechanisms achieve maximum national public benefits. The Department of Transportation's draft Framework for a National Freight Policy takes a step forward, but more is needed to guide the implementation of a federal role in freight transportation investments.
