Snow on the tracks caused a green line MBTA trolley to become stuck at Coolidge Corner.
Investigators are taking a close look at performance of the trolley driver who has a lengthy driving record.
An MBTA trolley crashed into a car that turned onto the tracks in Allston Monday night.
The MBTA says human error is to blame for the Green Line crash. Two passengers and a trolley operator say they have back and neck pain.
Effective Tuesday, at most above-ground stops on the D-Line, only the front doors of the trolleys will open.
Starting next week, the “T” will nearly triple the number of three-car trains on the Green Line. They will also add the trains to the E-branch.
