Train driver in fatal NYC crash had undetected sleep disorder: NTSB

By Jonathan Allen NEW YORK (Reuters) – The driver of a train that derailed in December in New York City, killing four passengers, had an undiagnosed sleep disorder at the time of the accident, the National Transportation Safety Board said on Monday. William Rockefeller, the engineer at the controls of the Metro-North commuter train that derailed in the Bronx on December 1, suffered from severe sleep apnea, which can cause drowsiness, according to documents published by the safety board on Monday. The documents also included a transcript of Rockefeller's interview with investigators two days after the crash, which provides the fullest account yet of the "hypnotic" state he said overcame him before he realized his train was derailing. "I was dazed, you know, looking straight ahead, almost like mesmerized," Rockefeller told investigators.
