Since opening in 1976, the Metro network has grown to include five lines, 86 stations, and 106.3 miles (171.1 km) of track. The rail network is designed according to a spoke-hub distribution paradigm, with rail lines running between downtown Washington and its nearby suburbs. The system makes extensive use of interlining – running more than one service on the same track. There are five operating lines and one line under construction. The system's iconic official map was designed by noted graphic designer Lance Wyman and Bill Cannan while they were partners in the design firm of Wyman & Cannan in New York City.

There are 40 stations in the District of Columbia, 15 in Prince George's County, 11 in Montgomery County, 11 in Arlington County, six in Fairfax County, and three in the City of Alexandria. The Silver Line will add 11 new stations, eight in Fairfax County and three in Loudoun County, Virginia.

About 50 miles (80 km) of Metro's track is underground, as are 47 of the 86 stations. Track runs underground mostly within the District and high-density suburbs. Surface track accounts for about 46 miles (74 km) of the total, and aerial track makes up 9 miles (14 km). At 196 feet (60 m) below the surface, the Forest Glen station on the Red Line is the deepest in the system. There are no escalators; high-speed elevators take 20 seconds to travel from the street to the station platform. The Wheaton station, next to Forest Glen station on the Red Line, has the second-longest continuous escalator in the world, the longest in the Western Hemisphere, at 230 feet (70 m). The Rosslyn station is the deepest station on the Orange/Blue Line, at 97 feet (30 m) below street level. The station features the third-longest continuous escalator in the Metro system at 205 feet (62 m); an escalator ride between the street level and the mezzanine level takes nearly two minutes.

The system is not centered on any single station, but Metro Center is at the intersection of the Red, Orange and Blue Lines, the three busiest lines. The station is also the location of WMATA's main sales office. Metro has designated five other "core stations" that have high passenger volume, including: Gallery Place, transfer station for the Red, Green and Yellow Lines; L'Enfant Plaza, transfer station for the Orange, Blue, Green and Yellow Lines; Union Station, the busiest station by passenger boardings; Farragut North; and Farragut West. In order to deal with the high number of passengers in transfer stations, Metro is studying the possibility of building pedestrian connections between nearby core transfer stations. For example, a 750-foot (230 m) passage between Metro Center and Gallery Place stations would allow passengers to transfer between the Orange/Blue and Yellow/Green Lines without going one stop on the Red Line. Another tunnel between Farragut West and Farragut North stations would allow transfers between the Red and Orange/Blue lines, decreasing transfer demand at Metro Center by an estimated 11%. The Farragut tunnel has yet to be physically implemented, but was added in virtual form effective October 28, 2011. The SmarTrip system now interprets an exit from one Farragut station and entrance to the other as part of a single trip, allowing card holders to transfer on foot without having to pay a second full fare.

Metro runs special service patterns on holidays and when events in Washington may require additional service. Independence Day activities require Metro to adjust service to provide extra capacity to and from the National Mall. WMATA makes similar adjustments during other events, such as presidential inaugurations. Metro has altered service and used some stations as entrances or exits only to help manage congestion.

In an effort to gain revenues, WMATA has started to allow retail ventures in Metro stations. WMATA has authorized DVD-rental vending machines and ticket booths for the Old Town Trolley Tours and is seeking additional retail tenants.
