Video: Boston Train Catches Fire Atop Bridge, Woman Jumps Into River

An emergency evacuation out of a subway train that caught fire was undertaken atop a bridge on the outskirts of US' Boston on Friday.

About 200 people had to be evacuated out of the train, authorities said. While most escaped through windows of the train, one woman jumped into the Mystic River below.

After a preliminary inspection, authorities found that a section of the sheet metal, or side panel, on the vehicle, appeared to have come in contact with the third rail, igniting material below the car.
