New rail connections to Dulles International Airport, Reston, Herndon, and Eastern Loudoun County

Metro celebrated the opening of the Silver Line Extension on November 15, 2022, connecting customers to six new stations, adding 11.4 miles of track to the Metrorail system, and beginning operations at a modern rail maintenance facility. The Silver Line Extension provides customers with a new connection to Washington Dulles International Airport, as well as service between Reston, Va. and eastern Loudoun County. The grand opening also marks the completion of the Silver Line project, a generational infrastructure investment in Northern Virginia.

Welcome aboard and get ready to ride by checking out the station pages listed below to view the virtual station tours, maps, and connecting bus routes.

Six new Metrorail stations are part of the Extension:

As one of the largest capital construction projects in the United States, the Silver Line provides high-quality, high-capacity transit service between the Dulles corridor and Downtown D.C.; expands the reach of the existing regional rail system; offers a viable alternative to automobile travel; and supports future development.

The Silver Line Extension also includes a brand-new rail maintenance and service yard, located on 90 acres of the Washington Dulles International Airport property. The Dulles Rail Yard is the largest rail yard in the Metro system and employs approximately 450 people.

The Silver Line Extension opening follows nearly five months of testing, training and safety certification efforts by Metro. Metro took control of the Silver Line Extension from the Metropolitan Area Airports Authority (MWAA) after the project achieved its Operational Readiness Date (ORD) on June 23, 2022. Since then, Metro has been testing the new tracks and equipment, and training staff at the stations, railyard, and maintenance facilities in preparation for opening to the public.
