There is continued terrorist interest in attacking the rail system either as the primary target or as an attack mechanism. The US railroad system includes 800 railroads, 144,000 miles of track, and 212,000 railroad crossings. First responders should work closely with railroad police departments and other security partners to better protect rail assets—including freight rail (railcars loaded with commodities or hazardous materials), passenger rail (Amtrak, regional, or commuter rail), heavy rail (metro, and subway), and light rail (street cars, tramways, or trolleys)—from terrorist attacks and criminal activities. This product was developed to provide general rail safety tips and resources to help increase first responder awareness of the rail environment.
