A Green Line trolley bumped into another trolley Thursday at the Boylston Street MBTA station, resulting in several injuries.

Boston firefighters and EMS workers responded to the accident and tended to the injured.

Emergency medical workers set up a triage operation on the sidewalk at the station to evaluate the passengers.

MBTA spokesman Joe Pesaturo said one trolley car “bumped into another,” but there was no derailment and no visible damage.

The station was closed off after the accident.
