Washington, D.C., commuters will continue to suffer from reduced rail service through the end of the year, the Washington Metropolitan Area Transit Authority confirmed Monday.

Residents can be expected to deal with the “current (reduced) rail service levels” through Dec. 31, according to the statement from WMATA. The metro service explained that as a result of “global supply challenges,” it is still awaiting parts and has no set time frame on when it will return the 7000-series fleet to the tracks.
