The Green Line tracks at Park Street were cleared by 11:20 p.m., and the T resumed Green Line service - but trolleys bypassed the station.
After repeatedly trying to shut down the turnpike, the O'Neill Tunnel and Storrow Drive, protesters against a New York grand jury's decision not to indict a police officer in Eric Garner's death swarmed the Park Street T stop around 10:30 p.m. and managed to shut down the Green Line - by standing on the tracks before having a die-in.
The T shut down the station and had Red Line trains bypass it. Downtown Green Line riders were told to take the Orange Line.
