DHS/TSA/PIA-050 Amtrak Rail Passenger Threat Assessment

The Transportation Security Administration (TSA) is responsible for security in all modes of transportation, including surface modes such as rail. Amtrak is a national passenger rail operator managing more than 300 trains a day to more than 500 destinations in the United States and Canada. To assess the operating environment from a risk perspective, Amtrak has requested that TSA assess the use of Amtrak trains by known or suspected terrorists. To conduct the assessment, Amtrak will provide TSA with rail passenger personally identifiable information (PII) collected over the course of several months for TSA to match against the Threat Screening Center’s (TSC) Terrorist Screening Database (TSDB), commonly known as the “watchlist.” TSA is conducting this Privacy Impact Assessment (PIA) pursuant to the E-Government Act of 2002 because this assessment entails a new receipt of personally identifiable information on members of the public for watchlist matching.
