Summary

Tunnels and the mass transit passengers who travel through them are subject to various threats. Many attacks that are planned against tunnels intend to kill or injure large numbers of people. Because of their open architecture, passenger transit tunnels and tunnel stations present an attack opportunity and a potential for significant consequence. This recommended practice provides recommended security strategies for agencies with transit tunnel assets to reduce risk to these structures.
