Green Line Extension track defects could take weeks to repair, GM says

MBTA General Manager Phil Eng says contractors could fix the defects on the Green Line Extension as soon as mid-November.

Why it matters: The highly anticipated line, which runs through Somerville and Medford, already needs an overhaul less than a year after opening.

Catch up fast: Eng said last week that more than half of the extension tracks need repairs because parts of the rails are too narrow.

Driving the news: Eng told the board of directors yesterday that contractors responsible for the project proposed working 10-14 nights to repair the tracks, starting Nov. 1, per WCVB.

• Contractors would need to stop service on the line from 9pm to 5am every day, the Globe reported.

Between the lines: Riders complained for months about the glacial pace of the Green Line Extension, only to learn about the narrow tracks.

• Eng said officials under former Gov. Charlie Baker knew that the rails were too narrow as early as April 2021, but that he didn't know until last week.

After last week's announcement about the defects, the T shut down the entire extension for several hours Friday evening, forcing riders to walk along the tracks.
