The Metro Transit Police Department is unique in American law enforcement. It is the only police agency that has local police authority in three different jurisdictions (Maryland, Virginia and the District of Columbia). The department has an authorized strength of 420 sworn officers, 106 security special police, and 24 civilian personnel. New officers complete twenty-three weeks of initial training at the Northern Virginia Criminal Justice Training Academy and then complete fifteen additional weeks of training at the Metro Transit Police Academy.
Uniformed and plainclothes Transit Police officers patrol the Metrorail system and Metrobuses on foot and on bicycles, and using motorcycles and marked and unmarked police cars. Transit Police Detectives provide investigative support. Transit Police officers have jurisdiction and arrest powers throughout the Metro service area for crimes that occur on Transit Authority facilities,
