    Half of the Union Square GLX branch and 80% of the Medford branch needs to
    be fixed, MBTA General Manager Phil Eng said Thursday.

    The MBTA knew as early as April 2021 that parts of the Green Line
    Extension were too narrow, an issue so widespread that the T now needs to
    widen roughly two-thirds of the almost brand-new rails, General Manager
    Phil Eng said Thursday.

    The $2.3 billion Green Line Extension opened just last year, making it the newest part of the T system.

    Earlier this fall, the transit agency confirmed that narrow track gauge
    was to blame for speed restrictions that slowed GLX trolleys to a 3 mph
    crawl. While the T lifted those slow zones last week, Eng said in a press conference that half of the Union Square branch and 80% of the Medford
    branch now needs to be regauged.

    “That does not mean that the trains are running today unsafely,” he added.
    “It means that we’re going to have the GLX constructors regauge the track
    to bring it back to what the project called for.”

    Eng, who took charge of the MBTA earlier this year, said he only recently
    found out about the gauge issues. He explained that a review of project
    records found that GLX construction crews and inspectors first identified
    an instance of “tight gauge” back in April 2021.

    “While those conditions were addressed, I believe that at that time, it
    was the appropriate time and should have been when the project team and
    design builders took a look at how we had those conditions exist,” he
    said.

    In November 2022 — when the Union Square branch was already running and
    the Medford branch was about to open — crews found 29 spots where the
    gauge was too narrow and made repairs, according to Eng. The same
    inspection also identified “significant portions” of both branches “that
    had tight gauge, but not restrictable gauge, meaning you could run trains safely,” he said.

    That, too, was an opportunity for the MBTA to address track conditions
    prior to the GLX opening, according to Eng. Instead, he said, project
    leaders ultimately decided to address the issues later “as part of a
    project close-out.”

    The team “could have been more proactive and should have been more
    proactive,” Eng asserted.

    Why are the tracks defective?
    The T is still reviewing what caused the narrow gauge, but Eng said he
    believes the problem stems from the fabrication of the rail ties and pre- installed plates — the wooden supports underneath the tracks and the metal plates anchoring them.

    According to The Boston Globe, regauging the tracks will involve
    unscrewing bolts from the tie plates, filling in the holes and drilling
    new ones, and securing the plates at the correct gauge.

    Internal emails obtained by the Globe showed members of the MBTA’s track department asked Green Line Extension manager John Dalton to fix not only
    the areas with the most narrow gauge — which would have required speed restrictions — but also thousands of other spots where the gauge remained outside construction specifications.

    The tracks were deemed safe when local, state, and federal officials
    gathered to cut the ribbon on the Medford branch last December because
    workers scrambled in those final days to fix the most serious problems,
    Eng told the Globe.

    What’s next for the GLX?
    Thursday saw a shakeup in leadership for the GLX project, with Eng tapping Chief of Capital Program Support Maureen McDonough to serve as acting
    Green Line Extension program manager. T spokesperson Joe Pesaturo also confirmed that two individuals with senior roles on the project are no
    longer employed by the T, though he did not identify them.

    During the press conference, Eng said the team that built the GLX has
    offered a proposal for bringing the gauge back within the project
    requirements.

    “The goal is to make sure, now that we’re aware of this situation, that
    they’re addressed timely, addressed properly so these situations aren’t continuing to repeat,” he said, later adding, “It’s not going to be years;
    it’s not going to be months. The proposal that we have is weeks.”

    Eng also suggested that the public should not be asked to foot the bill
    for repairs, asserting: “This is not something that the public should be
    paying for.”

    In a statement, Gov. Maura Healey praised Eng for “uncovering this and
    taking swift action to hold people accountable and demand a work plan from
    the contractor to fix the narrow gauges on their own dime.”

    Like Eng, Healey took office after the GLX had already opened; former Gov. Charlie Baker and then-MBTA General Manager Steve Poftak saw the project through to fruition.

    “I share the public’s frustration and disappointment at the revelation
    that senior MBTA officials under the previous administration knew about
    issues with the Green Line Extension tracks years ago and did not disclose
    them to our administration or address them on their watch,” she said. “The people of Massachusetts deserve better.”
