Dangerous, outdated rail cars are moving millions of gallons of oil from the Midwest to New York, and safety experts say they can easily explode if they derail.

The DOT-111 tank cars, which make up about 70 percent of the cars used by the energy industry, have thin shells that easily crack open if a train goes off the tracks.

They are also prone to failure, the National Transportation Safety Board has said after investigating fiery crashes involving the tank cars

Sen. Charles Schumer (D-NY) called for new federal requirements that all future tank car purchases to be safer, more modern models.

“The thought of a train jumping the tracks is scary enough,” said Schumer. “A train derailing while carrying millions of barrels of oil in tank cars, that’s really frightening.”
