As the National Transportation Safety Board, or NTSB, continues to investigate Sunday's deadly New York train derailment, the agency has learned the train's engineer lost focus moments before the train went off the tracks.

The New York Times reports Rockefeller, a 46-year-old veteran engineer, admitted to several people that he wasn't fully attentive before the train wreck. Union Representative Anthony Bottalico described it as "highway hypnosis" or zoning out.

Investigators say Rockefeller's alcohol tests came back negative but a more thorough review of his cell phone usage is still underway. He's currently on leave without pay.
In the meantime, Metropolitan Transportation Authority, or MTA, crews have begun repairing the tracks near the site of the derailment. According to WCBS, MTA officials say partial service to those tracks should be restored Wednesday.
