NEW YORK (REUTERS) - The driver of a New York commuter train that derailed on Sunday, killing four people, told investigators he "lost focus" and went into a daze shortly before the crash, according to a law-enforcement source.
A second source also briefed on the investigation said the driver, William Rockefeller, 46, lapsed into a "highway hypnosis". The seven-car Metro-North train was traveling at 82 miles per hour (132 kph), nearly three times the 30-mph (48-kph) speed limit for the curved section of track where it crashed, investigators have said. The brakes were applied just seconds before it derailed.
The crash also critically injured 11 people and snarled travel for the roughly 26,000 regular commuters on the Metro-North Hudson line which serves suburbs north of New York City.
The National Transportation Safety Board (NTSB) has cautioned that their investigation would continue for weeks, if not months, and they were far from reaching a conclusion on the cause.
Rockefeller, who has never been disciplined for job performance as train driver, told investigators the train was operating normally when somehow he slipped into a daze, said the law-enforcement source, who has access to official reports on the investigation and requested anonymity.
Rockefeller told investigators he could not fully recall what happened but that at some point he suddenly came out of the temporary daze, realized the train was going too fast and into a dangerous curve, and applied the brakes. It was too late to avoid the crash.
Law-enforcement agencies including the Bronx district attorney, the New York Police Department and transit police are monitoring the investigation.
If criminal charges are warranted, they would be brought by Bronx District Attorney Robert Johnson, a spokesman for Johnson said.
Asked whether Rockefeller dozed off, the second source said: "It's more like a highway hypnosis. You're looking straight ahead and you're seeing rail and rail and rail and you lose perspective."
The train's throttle was reduced to idle six seconds before derailing and its brakes were activated five seconds before the accident, National Transportation Safety Board (NTSB) member Earl Weener told a news conference on Monday.
