The Amtrak Police Department (APD) is a quasi-federal railroad police department and the law enforcement agency of Amtrak (also known as the National Railroad Passenger Corporation), the government-owned passenger train system in the United States. It is headquartered at Union Station in Washington, D.C., and as of 2019 has a force of 452 sworn police officers, most of whom are stationed within the Northeast Corridor, Amtrak's busiest route. The APD has primary jurisdiction over Amtrak stations nationwide, trains, rights-of-way, maintenance facilities, and crimes committed against Amtrak, its employees, or its passengers. The APD is one of six American Class I railroad law enforcement agencies, alongside those of BNSF, CSX, Kansas City Southern, Norfolk Southern, and Union Pacific. Since 1979, most Amtrak police officers are trained at the Federal Law Enforcement Training Centers (FLETC) although some recruits may be certified through a local police academy. Authority Created by Congress, Amtrak's enabling legislation under the Rail Passenger Service Act of 1970, now codified starting at 49 U.S.C. 24101, established the authority for Amtrak to have its own police force. The statutory authority was unique at the time and included interstate police powers. The Amtrak rail police law, now found at 49 U.S.C. 24305 (e), states as follows: In sum, Amtrak police officers have the same police authority as a local or state law enforcement officer, within their jurisdiction. They investigate various types of crime that occur within and around stations, trains and/or right of ways. Counter-terrorism Since the September 11, 2001 attacks, APD has become more terrorism-focused. Such mission shift became even more prevalent after the Madrid train bombings in 2004. It maintains a robust K-9 division composed of patrol and bomb dogs. Police cover APD officers constantly work in partnership with federal, state and local law enforcement to perform their duties in accordance with the agency's mission to protect America's railroads. In theory, officers have jurisdiction in all the 46 states where Amtrak operates, but are stationed more in busier locations in practice. Operational Divisions Each of the Divisional Commands provide different police services for the geographical area they cover. The different divisions within the department can be categorized as the following: Patrol Division – Patrol Officers fulfill traditional policing functions. They act as a deterrent to crime in the stations, on trains, in and around Amtrak facilities, and out on the rights-of-way by enforcing laws, providing support at stations, and
