Four people were injured when a runaway cable car derailed Sunday.
The Powell-Mason cable car became stuck shortly before midnight while making a left turn on Washington Street from Mason Street. Both operators got out to push, but the vehicle then began rolling downhill, said Muni spokesman Judson True.
One operator got back on but could not reach the brakes because a door wouldn’t open. The other operator tripped while trying to board.
The vehicle derailed on Powell Street. One woman suffered a broken leg, True said.
The accident is under investigation. Both operators have been tested for drugs and alcohol and placed on administrative leave.
