Damaged train finally removed from Cambridge tracks after derailment

CAMBRIDGE - A derailed Green Line train in Cambridge has finally been moved, about a day-and-a-half after it derailed , and regular service has resumed.

Green Line derailment

Seven people were hurt Tuesday evening when the train derailed after leaving Lechmere station around 5 p.m.

The Massachusetts Bay Transportation Authority (MBTA) said the lead trolley's wheels came off the tracks. That caused another car to derail, but it remained upright.

Investigators from the National Transportation Safety Board (NTSB) have been looking into the cause. Their preliminary report should be done in about a month.

Full service restored

The damaged train was finally removed early Thursday morning from the area of the Red Bridge where the Medford/Tufts branch and Union branch intersect.

Shuttle buses were used through the morning rush hour. Full service on the Green Line resumed around 10:30 a.m. Thursday

"We're working alongside our federal and state partners to understand what happened to make sure this doesn't happen again," MBTA General Manager and CEO Phillip Eng said in a statement .

The derailment happened in the same spot where the line closed in October 2023 because of a power failure. The rails on the entire Green Line Extension had to be repaired. Massachusetts Governor Maura Healy said Tuesday's derailment had nothing to do with the rail or the track.

"The look is at the operator," Healey told reporters Wednesday, adding that she's leaving that to the NTSB.
