See privacy policy.The Silver Line is slowly creeping to Dulles Airport (IAD) in what would be the first rail connection between downtown Washington, DC and Washington-Dulles Airport. Travelers have had to rely on buses or cars for all or part of their journey to the United Airlines hub, which serves more than 20 million passengers per year.Slated to begin service to the new Dulles Airport station in 2020, the Silver Line already connects nearby Reston, Virginia, to the DC area.
