Boston Green Line Signal Fix Brings Service Back
Green Line D Branch experiences 15-minute delays after signal problem between stations
Green Line D Branch Faces 15-Minute Delays
Boston's Green Line D Branch is experiencing 15-minute delays following a signal problem between Brookline Hills and Beaconsfield stations, transit officials said Friday. The technical issue has been resolved, but residual delays continue to affect the approximately 45,000 riders who typically use the D Branch on weekdays. Service is operating along the 25-station route, though passengers should plan for additional travel time.
Signal Problems Persist Across MBTA System
The disruption highlights ongoing signal system challenges that've affected the Green Line in recent years. The MBTA has been working on signal system upgrades across the Green Line as part of broader modernization efforts, according to the transit agency. Federal Transit Administration officials placed the MBTA under enhanced safety oversight in 2023, increasing scrutiny of maintenance issues including signal system reliability. Officials didn't provide specific details about what caused Friday's signal malfunction or how long repairs took.
Service Continues With Reduced Reliability
The signal problem occurred earlier Friday between two stations on the D Branch's western section, though officials haven't said exactly when the issue began or was resolved. Transit officials confirmed via social media that the technical problem has been addressed, but didn't specify what repair work was needed. The agency hasn't released information about how many trains were delayed or how many passengers were affected by the disruption. Signal-related delays are common across aging transit systems, with New York's MTA experiencing frequent similar disruptions.
Normal Service Expected to Resume Soon
The MBTA continues monitoring the situation to ensure service returns to normal operations, officials said. The agency didn't provide a specific timeline for when delays will fully clear. Transit officials typically share service alerts through social media for routine operational issues rather than issuing formal statements. Federal safety standards require transit agencies to maintain signal systems and report significant failures.
Riders Advised to Plan Extra Travel Time
Passengers using the D Branch should continue planning for 15-minute delays until the MBTA confirms normal service has resumed. The agency shares real-time updates through official channels as conditions change. Riders can access current service information and trip planning through Moovit, which provides real-time updates for MBTA routes throughout the Boston area.
