More than 300 people were evacuated from a passenger train in Ridley Park, Pennsylvania after a fire started under the first car. The blaze quickly engulfed an entire carriage.

The Southeastern Pennsylvania Transportation Authority (SEPTA) said all passengers were safely evacuated and no one was injured. “The pictures really tell the story of how serious this situation was,” said Andrew Busch, SEPTA Director of Media Relations. The cause of the fire is under investigation.
