Boston Green Line Bounces Back After Morning Delays

Switch malfunction and disabled train caused 25-minute delays on Green Line D Branch

Green Line D Branch Resumes Normal Service

Boston's Green Line D Branch has returned to normal operations after morning delays stretched up to 25 minutes, transit officials said Thursday. The disruptions affected commuters traveling along the branch during the morning rush, though service has since been restored. Officials confirmed the issues were resolved and trains are running on regular schedules.

Dual Technical Issues Caused Disruption

The delays stemmed from two simultaneous problems that compounded service difficulties, according to the transit agency. A switch malfunction at Reservoir station created operational challenges for train movements, while a disabled train at Elliot further impacted the line's ability to maintain schedules. Transit agencies typically prioritize resolving switch problems and disabled trains quickly, as both can create cascading delays across a line. Officials didn't specify how long crews worked to clear the issues or what caused the train to become disabled.

25-Minute Delays Hit Morning Commuters

Passengers experienced delays of approximately 25 minutes during the disruption, officials said. The combined impact of the switch problem and disabled train affected multiple trains along the D Branch, which runs from Government Center through Kenmore and Brookline to Riverside. Officials didn't say how many trains were affected or how many riders experienced delays. The D Branch is one of four Green Line branches and serves several major destinations including Fenway Park and Longwood Medical Area.

Service Restoration Completed Thursday

Transit crews resolved both issues and restored normal service Thursday morning, though officials didn't provide a specific timeline for when the problems were cleared. The agency typically works to address switch malfunctions and disabled trains as quickly as possible to minimize rider impact. Officials said trains are now operating on regular schedules along the D Branch.

Riders Can Check Real-Time Updates

Commuters affected by the delays can now expect normal travel times along the D Branch. Transit officials said service has returned to regular operations with no residual impacts expected. Riders can check Moovit for real-time Green Line updates and service alerts to stay informed about any future disruptions on the D Branch or other MBTA lines.
