Yellow Line (Washington Metro). The Yellow Line is a rapid transit service of the Washington Metro, connecting suburban Virginia with downtown Washington, D.C.. It operates between Huntington in Fairfax County and Mount Vernon Square in the District of Columbia, with extended Rush hour service to Greenbelt in Prince George's County. The line primarily serves the Potomac River corridor, providing critical connections through Arlington and across the National Mall.
History
The Yellow Line's history is intertwined with the development of the Washington Metro system, with its first segment opening in 1983 as part of the system's second major phase. Initial service ran between the National Airport and Gallery Place stations, utilizing the newly opened Potomac River crossing. A major extension south to Huntington opened in 1983, completing the line's Virginia segment. For decades, its northern terminus was at Mount Vernon Square, but service patterns were significantly altered with the 2006 opening of the Red Line's New York Avenue station and subsequent track connections. This allowed the introduction of Rush+ service in 2012, extending some Yellow Line trains to Greenbelt via the Green Line's route.
Route
The route begins at the Huntington station in Fairfax County, traveling north through the George Washington Memorial Parkway corridor. It serves Alexandria at stations like King Street–Old Town before crossing the Potomac River via the Yellow Line Bridge, a dedicated transit structure. Upon entering the District of Columbia, the line runs beneath Crystal City and Pentagon City in Arlington, serving the Pentagon and L'Enfant Plaza. Through downtown Washington, D.C., it shares tracks with the Green Line from the Archives to Mount Vernon Square. During peak periods, Rush+ trains continue north on Green Line tracks to Prince George's County, terminating at Greenbelt.
Stations
The line serves 13 stations during base service, with an additional 14 during Rush+ operations. Key Virginia stations include the terminus at Huntington, Braddock Road, and King Street–Old Town. Major transit hubs on the line are Pentagon, offering connections to the Blue Line, and L'Enfant Plaza, a major interchange with the Orange, Silver, Blue, and Green Lines. In Washington, D.C., important stations include Archives, Gallery Place (with connections to the Red Line), and the terminus at Mount Vernon Square. Rush+ service adds stations like Columbia Heights and Fort Totten.
Service and operations
Base service operates between Huntington and Mount Vernon Square. During weekday peak periods, Rush+ service operates, with some trains continuing to Greenbelt. This service pattern provides a direct connection between Virginia and Prince George's County. Headways vary by time of day, with the line interfacing with the Washington Metropolitan Area Transit Authority's overall scheduling. The line experiences high ridership at stations serving major employment centers like the Pentagon, L'Enfant Plaza, and the Federal Triangle.
Rolling stock
The Yellow Line operates using the Washington Metropolitan Area Transit Authority's standard fleet, which includes 2000-series, 3000-series, 6000-series, and 7000-series railcars. Trains are typically configured in six-car or eight-car consists. The newer 7000-series cars, which began entering service in 2015, have gradually replaced older equipment. All rolling stock is maintained at the Washington Metropolitan Area Transit Authority's Greenbelt Maintenance Yard and other facilities.
Future
Future plans for the Yellow Line are part of the broader Washington Metro strategic initiatives. The Potomac Yard station, located between the Braddock Road and National Airport stations, opened in 2023, adding a new infill station. Long-term proposals in various Washington Metropolitan Area Transit Authority planning documents have occasionally studied potential extensions further into Virginia, though no such projects are currently funded or under construction. Service patterns may continue to evolve with the expansion of the Silver Line and other system changes managed by the Washington Metropolitan Area Transit Authority.
