REPORT: Human Error Caused Runaway Braintree Train

Braintree, MA - A train from Braintree that left the station unmanned was the result of human error, a new report said.

Sources tell WHDH that there was no criminal intent when the Red Line train left the Braintree MBTA station just after 6 a.m. this morning.

The report conflicts what Gov. Charlie Baker said, who told reporters Wednesday afternoon that the main control of the train was tampered with.

At 6:08 a.m., an inbound train left the Braintree station without a driver after the operator left the train to check a signal issue. The train traveled through Quincy before stopping north of the North Quincy station. Operations personnel halted the train by depowering the third rail.

Workers for the T were able to board the train and take it to JFK/UMass, where passengers were able to leave the train before it was taken out of service.

No passengers were injured, but the operator is being treated for non-life-threatening injuries at South Shore Hospital.
