The latest slowdown of Metro's 9-month maintenance blitz will be more disruptive than initially planned.
Red Line trains will continuously single-track between the Shady Grove and Twinbrook Metro stations starting Tuesday.
On weekdays, trains will serve the Shady Grove and Rockville stations every 18 minutes.
All other Red Line stations will have near-normal service, WMATA said.
Additional trains will operate between Twinbrook and Glenmont and between Grosvenor and Silver Spring during the morning and afternoon rush.
Midday and evening trains between Shady Grove and Silver Spring will operate every 18 minutes. Between Grosvenor and Glenmont, trains will operate every 12 minutes, WMATA said.
After 10 p.m., trains between Shady Grove and Glenmont stations will run every 20 minutes, according to WMATA.
WMATA is encouraging ridingers to avoid the Shady Grove and Rockville stations, if possible.
Weekend train schedules may change to coordinate with other planned track work on the Metrorail system, WMATA said.
The work zone will be extended the weekend of Aug. 13 and Aug. 14, to include a line segment shutdown between Shady Grove and Grosvenor-Strathmore stations. Free shuttle buses will replace the trains.
On Aug. 20 and Aug. 21, free shuttle buses will replace Red Line trains between Grosvenor and Shady Grove stations. White Flint, Twinbrook, Rockville and Shady Grove stations will be closed during this time.
Additional weekend service information will be posted here.
Red Line track disruption will last through Thursday, Aug. 18.
