More than a year after a Green Line train lurched off the tracks near Lechmere on Oct. 1, 2024, newly released surveillance footage finally shows the exact moment things went sideways, sending riders scrambling across the rails. Roughly 50 people were aboard, and seven riders were taken to nearby medical facilities with minor injuries after the derailment. The video adds stark, graphic context to what federal investigators had already laid out on paper.
The clip, released this week, shows the lead car lifting and tipping at the Red Bridge interlocking as passengers pour out and climb across the tracks toward a service road. According to NBC Boston, seven people were taken to medical facilities with minor injuries.
What the NTSB found
In its final report, the National Transportation Safety Board determined the probable cause was “the operator failing for unknown reasons to obey a stop signal,” according to NTSB. The board said the leading railcar entered a 10-mph zone at about 36 mph and that the first wheelsets ran straight while the next sets took the diverging track, causing the car to derail. Investigators also cited gaps in MBTA speed-compliance audits and recommended safety technologies to reduce the consequences of human error.
