NTSB Investigates MBTA Green Line Derailment

A derailment of an MBTA Green Line train near Lechmere Station in Cambridge on Tuesday evening has led to significant service disruptions, with shuttle buses replacing train service indefinitely. Seven passengers sustained minor injuries, and approximately 50 people self-evacuated. Preliminary investigations have ruled out track issues, focusing instead on human error as a potential cause. The National Transportation Safety Board (NTSB) is leading the investigation, which could take several days. Federal, state, and local agencies are collaborating to determine the incident's cause and prevent future occurrences. Normal service will resume once the investigation concludes and necessary repairs are made.
