Boston Green Line Signal Fixed, Service Recovering

Signal problem at Kenmore station resolved but 15-minute delays persist on Green Line

Green Line Faces 15-Minute Delays After Signal Fix

Boston's Green Line is experiencing 15-minute delays Sunday following a signal problem at Kenmore station, transit officials said. The technical issue has been resolved, but residual delays continue to affect riders across the line. The MBTA announced the disruption via its official social media channels, advising passengers to plan for additional travel time.

Signal Problems Common on Aging System

Signal issues are a recurring challenge for the MBTA's aging infrastructure, according to the transit agency. The Green Line, which dates to 1897, is one of the oldest subway lines in the United States. The MBTA has ongoing signal modernization projects across multiple lines, including the Green Line, as part of broader infrastructure improvements. Officials didn't specify what type of signal malfunction occurred at Kenmore or which specific equipment failed.

Delays Affect All Green Line Branches

The 15-minute delays are affecting service across the Green Line system, transit officials said. The MBTA didn't specify which of the line's four branches—B, C, D, or E—experienced the most significant impacts. Officials said service is proceeding following the resolution of the technical problem, though they haven't provided an estimate for when normal service levels will fully resume. The agency typically posts updates to its social media channels as conditions change.

Issue Resolved But Delays Continue

The signal problem at Kenmore was resolved earlier Sunday, according to the MBTA, though officials didn't provide specific times for when the issue began or when repairs were completed. Transit officials said the residual delays stem from the earlier disruption's impact on train positioning and scheduling. The agency hasn't said how long riders should expect the lingering delays to continue.

Riders Advised to Plan Extra Time

Passengers using the Green Line Sunday should allow an additional 15 minutes for their trips, transit officials said. The MBTA posts real-time service alerts through its official social media channels and other communication platforms. Moovit provides real-time updates for MBTA Green Line service, helping riders plan around delays and track train arrivals.
