Red Line Adds 15-Minute Delays at JFK/UMass

Red Line riders faced 15-minute delays Friday due to a signal problem at JFK/UMass station, transit officials said. The Massachusetts Bay Transportation Authority reported the disruption affected Ashmont Branch service, though specific timing of when the problem began and was resolved wasn't immediately available. The Red Line serves approximately 200,000 passengers on an average weekday, making even brief delays significant for commuters.

Signal Problems Persist During Modernization

The signal malfunction comes as the MBTA works through a comprehensive signal system modernization program launched in 2023 for the Red Line. Transit officials said signal problems remain a recurring issue during the transition period as aging infrastructure is replaced. The agency's been under Federal Transit Administration enhanced oversight since 2022 due to safety concerns including signal system issues. Technical details about the specific malfunction weren't provided by the transit agency.

Ashmont Branch Service Affected

The signal problem specifically impacted Ashmont Branch trains passing through JFK/UMass station, according to the MBTA. Officials didn't say how many trains were delayed or whether shuttle buses were deployed to assist affected passengers. The extent of passenger impact wasn't immediately disclosed. Information about alternative service arrangements wasn't available, though the agency typically communicates such options through its alert system when delays exceed 20 minutes.

Brief Disruption Resolved Same Day

The 15-minute delays were reported Friday morning, though the MBTA didn't provide a specific timeline for when service returned to normal. Transit officials said the issue was resolved the same day. The agency hasn't said whether additional signal work is planned at JFK/UMass station to prevent similar problems.
