NTSB Investigates Train Derailment

As investigators continued to search for clues as to why a Metro-North Railroad passenger train flew off the tracks on Sunday morning, killing four people and injuring dozens more, Gov. Andrew M. Cuomo said on Monday morning that it appeared that the train was traveling too fast as it hit a curve in the tracks.

Four people died and nearly a dozen are critically injured after the train derailed in the Bronx.
