Metro SafeTrack to Disrupt Red Line from Shady Grove to Twinbrook

Beginning June 17, the Metro's Red Line will experience the final planned phase of SafeTrack. As a reminder, SafeTrack is an accelerated work plan to address safety recommendations and rehabilitate the Metrorail system (

From Saturday, June 17 continuing through Sunday, June 25, a five-mile segment of the Red Line between Shady Grove and Twinbrook will be shut down for nine days. Two stations -- Shady Grove and Rockville -- will be closed with rail service replaced by free shuttle buses running throughout the day. Customers who normally use Shady Grove or Rockville are encouraged to consider starting their trip at Twinbrook, White Flint, Glenmont or Wheaton during this period.

Elsewhere on the Red Line, trains will run at near-normal intervals:

  • Red Line trains will operate at near normal service between Twinbrook and Glenmont every 8 minutes (normally 6 minutes).
  • Additional Red Line trains will operate between Grosvenor and Silver Spring every 4 minutes (normally 3 minutes).
  • Service on Metro's Orange, Silver, Blue, Yellow and Green lines will not be affected.

The Office of Human Resources (OHR) encourages both supervisors and employees to proactively explore whether workplace flexibilities such as compressed work schedules, flexible work schedules, and telework may alleviate transportation issues for both regular metro riders and drivers who may experience increased traffic.

In an effort to provide additional service, the Office of Research Services, Division of Amenities and Transportation Services (DATS) is reaching out to registered Transhare Program employees who may be impacted based on their self-reported commutes through their Transhare application. Through these targeted e-mails, DATS will provide affected employees with additional commuter options.

Medical Center Metro Escalator Replacement

The Washington Metropolitan Area Transit Authority (WMATA) is beginning a major capital improvement project to replace the three escalators at the Medical Center Metrorail station. The current escalators have exceeded their useful life and will be replaced with new, reliable and durable escalators.  Metro's contractor, KONE, will install the new escalators as part of Metro's ongoing project to replace 128 escalators across the Metrorail system. The project is expected to take about 2.5 years, as most of the work will be conducted while the station is closed. During construction, one escalator at a time will be replaced, leaving access to the remaining two escalators. For more information and the full article, click here.
