Simulated service begins on Metro’s Silver Line

WASHINGTON — Metro is simulating service on its new Silver Line, with just five days left before it opens to rail commuters.

Metro began running Silver Line test trains on 11 miles of new track Sunday. The agency says riders on some other routes should expect delays this week, especially on the Blue Line, where wait times could increase from eight minutes to 12.

The trains are being run to test signals and train drivers along the route from Largo, Maryland, to Reston, Virginia.

Proponents say the new line and its five stations will help transform Tyson’s Corner, Virginia, from a driving destination into a walkable residential and commercial center.

The Silver Line is expected to carry about 25,000 passengers a day when it opens to the public on July 26.
