The introduction of the Silver Line represents a significant service increase for Metro. Once the line opens, Metro will run more trains and rail cars than at any point in its history.
About 37 percent of existing Metrorail riders, accounting for 260,000 Metrorail trips, will benefit from shorter wait times. These include rush-hour riders traveling to or from stations north of L'Enfant Plaza on the Green/Yellow lines, those traveling to or from stations east of Stadium-Armory on the Blue Line, and those along the Orange Line in Arlington County.
Silver Line will result in more frequent midday and evening service at 23 stations, from East Falls Church to Largo Town Center, and will result in more frequent weekend service for 40 percent of riders.
In addition to the 37 percent of Metrorail riders who will have a shorter wait time for a train, 53 percent will see no change in wait time, and only 10 percent will see longer wait times.
Of those riders who see a longer wait time, half are Blue Line riders — representing five percent of trips — who may encounter an average wait time increase of about two minutes longer. Today, Blue Line trains run an average of every 8.5 minutes during rush hour, resulting in an average wait time of about four minutes. Starting July 21, Blue Line trains will run every 12 minutes, resulting in a six-minute average wait time.
The only station along the traditional Blue Line that will see a net decrease in rush-hour trains is Arlington Cemetery. At all other stations, the number of trains will either increase or remain the same. At stations in Virginia from Pentagon to Franconia-Springfield, the share of Yellow Line trains will increase slightly (2 trains/direction/hour) to replace existing Blue Line trains.
Riders at outlying stations on the Orange Line account for the remaining five percent. The average trip time for these riders will increase less than a minute — from 1.8 minutes today to 2.7 minutes starting July 21.
