The Red Line is a rapid transit line of the Washington Metro system, consisting of 27 stations in Montgomery County, Maryland, and Washington, D.C., in the United States. It is a primary line through downtown Washington and the oldest and busiest line in the system. It forms a long, narrow "U," capped by its terminal stations at Shady Grove and Glenmont.

Trains run most frequently during morning and evening rush hours (nominally four to eight minutes apart) and least frequently after 9:30 p.m. (nominally 15 to 18 minutes apart).^[1]

The Red Line is the only line in the system that does not share its tracks with another Metrorail line. However, it operates parallel to CSX Transportation freight trains along the railroad's Metropolitan Subdivision from the D.C. neighborhood of Brentwood north past Silver Spring, Maryland, and continuing through Twinbrook.
