The U.S. passenger rail system is a vital component of the nation's transportation infrastructure, carrying more than 11 million passengers each weekday. The Department of Homeland Security (DHS) and the Department of Transportation (DOT) share responsibility for ensuring the safety and security of rail systems. In this report, GAO addressed (1) DHS actions to assess the risks to the U.S. passenger rail system in the context of prevailing risk management principles, (2) federal actions taken to enhance the security of the U.S. passenger rail system, and (3) security practices that domestic and selected foreign passenger rail operators have implemented. |
