WMATA preps for Green Line interlocking replacement

The Washington Metropolitan Area Transit Authority (WMATA) on Aug. 5 will kick off a capital improvement project to rebuild a Green Line interlocking.

The project involves replacement of four switches, as well as signal upgrades, power cable renewal, grout pad replacement, station rehabilitation, preventive maintenance and replacement of 1,500 crossties on a 4.5-mile section of track.

The work will require the temporary closure of the Branch Avenue and Suitland stations Aug. 5-20. The work zone will be extended to the Naylor Road Station Aug. 12-13 and Aug. 19-20.

The project requires simultaneous work on both tracks. The same work would take nearly three months to complete using weekend single tracking, WMATA officials said in a press release.

The work is scheduled during a time of year when ridership is lightest.

"These planned capital improvement projects are necessary to ensure the tracks are properly maintained, resulting in fewer delays for customers due to track issues," said Metro General Manager and Chief Executive Officer Paul Wiedefeld. "The long-term benefit is a safer, more reliable system and customers should experience a smoother, better ride."

The Green Line project is the first of three major trackwork projects planned as part of WMATA's new preventive maintenance and capital work program.

In fall, the agency will rebuild an interlocking outside the Takoma Station.
