Page "Washington Metro" Paragraph 19

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 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.
