An investigation is underway following the latest derailment of an MBTA Green Line trolley in Cambridge on Monday evening.
MBTA officials tell Newscenter5 that the NTSB is stepping in and taking over the investigation into the derailment that sent several passengers to the hospital with minor injuries. The MBTA said that they must halt all repairs and investigation until the federal investigators arrive.
"NTSB is sending a team to investigate Tuesday’s derailment involving a MBTA light rail passenger train near Somerville, Massachusetts. Team expected to arrive tonight and tomorrow morning," the NTSB said in a statement.
Shuttle bus service is replacing train service between North Station to Union Square and the Medford/Tufts station and is expected to continue until the end of service on Tuesday.
During a press conference outside of the Lechmere MBTA station, MBTA Chief Operating Officer Ryan Coholan said that the preliminary investigation has ruled out any issues with the track structure, and that the investigation is focusing on the human factors involved with the derailment.
