Flames leapt from the rails of a New York City area commuter train on Monday morning, filling at least one car with smoke and sending several passengers to the hospital for inhalation after they were evacuated, authorities said.

A roughly 30-second video posted to social media by a passenger showed thick smoke on a Port Authority Trans-Hudson train car at the Newport station in Jersey City, New Jersey. People can be heard on the video saying “open the door,” and “easy, easy,” as they eventually disembark.
