2 T Trolleys Bump At Boston's Boylston Station

Boston authorities said about three dozen people were taken to hospitals for evaluation or treatment of mostly minor injuries after an MBTA Green Line trolley bumped into the rear of another in a downtown subway station Thursday.

Boston Emergency Medical Services said nine people with head and neck injuries were transported on stretchers. None of the injuries are considered life-threatening.

MBTA Transit Police Superintendent Joseph O'Connor said at the scene a two-car train at the Boylston Street platform was rear-ended just before noon Thursday by an arriving two-car train. He said there was no derailment and no visible damage to the cars.

T spokesman Joe Pesaturo estimated up to 200 passengers were on board.

The station was closed during the investigation. Just after 2:30 p.m., the T tweeted that the station was opening and normal service routes were resuming.

O'Connor said it's too early to say what caused the crash.

"Transit Police detectives along with members of the safety department of the MBTA and operations will try to determine exactly what the facts and circumstances of this case are," O'Connor said.
