 The system is not centered on any single station, but Metro Center is at the intersection of the Red, Orange, Blue, and Silver 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, Silver, Green and Yellow Lines; Union Station, the busiest station by passenger boardings; Farragut North; and Farragut West.
