The Washington Metro, known colloquially as Metro and branded Metrorail, is the heavy rail rapid transit system serving the Washington metropolitan area in the United States. It is administered by the Washington Metropolitan Area Transit Authority (WMATA), which also operates Metrobus service under the Metro name. Besides the District of Columbia, Metro serves several jurisdictions in the states of Maryland and Virginia. In Maryland, Metro provides service to Montgomery and Prince Georges counties; in Virginia, to Arlingtonand Fairfax counties and the independent city of Alexandria. Combined with its ridership in the independent Virginia cities of Falls Church and Fairfax, the Metro service area is largely coextensive with the inner ring of the Washington metropolitan area. The system is currently being expanded to reach Dulles International Airport and Loudoun County, Virginia. It operates mostly as a subway in the District itself, while most of the suburban tracks are at surface level or elevated.
Opened in 1976, the network now includes six lines, 91 stations, and 117 miles (188 km) of route. Due to subway track depths, Metros Wheaton station has the longest, single-tier escalator in the Western Hemisphere, spanning 230 feet (70 m).
Metro is the third-busiest rapid transit system in the United States in number of passenger trips, after the New York City Subway and Chicago "L". There were 215.3 million trips on Metro in fiscal year 2015, or 712,843 trips per weekday. In June 2008, Metro set a monthly ridership record with 19,729,641 trips, or 798,456 per weekday. Fares vary based on the distance traveled, the time of day, and the type of card used by the passenger. Riders enter and exit the system using a proximity card called SmarTrip.
