Green Line Operator Put Train In 'Full-Power' Prior To July Crash

BROOKLINE, MA — The operator of the Green Line train that crashed into another train near Agganis Arena on July 30 placed the master controller in 'full-power position' prior to the accident, said the National Transportation Safety Board (NTSB) in a preliminary report Tuesday.

According to federal investigators, the striking train was going 31 miles per hour, three times the speed limit, when it crashed into another going 10 miles per hour.

The crash caused three train cars to derail and 27 people, including four MBTA operators, were taken to the hospital with non-life-threatening injuries.

The NTSB is expected to release more information regarding the crash in the coming weeks, shifting their focus to internal and external oversight, operational testing, crashworthiness of the equipment involved, and employee fitness for duty.

Once the NTSB releases its final report, Gov. Charlie Baker said he is prepared to make any recommended changes.
