The Yellow Line is a rapid transit line of the Washington Metro system that runs between Huntington in Virginia and Mount Vernon Square in Washington, D.C. It consists of 13 stations in Fairfax County, the city of Alexandria, and Arlington County in Virginia, and Washington, D.C. It is the shortest line in the system, and since its truncation to Mount Vernon Square, it is the only line that does not enter Maryland.
The Yellow Line shares track with the Blue Line between King Street–Old Town and Pentagon and the Green Line between L'Enfant Plaza and Mount Vernon Square. It has only two stations that are not shared by any other lines (Huntington and Eisenhower Avenue) and only two sections of track that are not shared by any other lines – the section south of King Street–Old Town and the section between Pentagon and L'Enfant Plaza, crossing the Potomac River.
On weekdays, trains run every 6 minutes until 9:30PM and every 7.5 minutes afterward. On weekends, trains run every 8 minutes.
