Engineer of Derailed Metro North Train Reportedly Admitted to "Zoning Out," Falling Asleep While Tak

The engineer operating a commuter train that derailed in New York City Sunday, killing four, told investigators that he had "zoned out" and was "falling asleep" as the train headed into a curve well at more than double the posted speed limit, according to reports.

Engineer William Rockefeller said he was jolted back to reality only after a whistle went off in the front of the train warning him that he was going too fast, sources added, according to the New York Post.
