RESTON, Va. (AP) — Metro says the new Silver Line makes the Washington region’s transit system 10 percent larger with the addition of five new stations.

The first train departed Reston on Saturday after about 50 years of planning and more than five years of construction. Within the first few hours, 10,000 people had entered or exited one of the new Silver Line stations.

About 25,000 daily riders are expected to use the five new stations after the Silver Line line’s first year of service.

Beginning this week during rush hour, Silver Line trains will run every six minutes. They will run every 12 minutes during midday, evenings and weekends. Trains will run every 20 minutes during late-night hours.

Metro says the Silver Line increases service for more than a third of its existing riders.
