NEW YORK Federal investigators say they're allowing the cars from a derailed New York commuter train to be turned upright to check for any other possible victims.
The National Transportation Safety Board held a briefing Sunday afternoon to discuss the Metro-North derailment earlier in the day that killed four people and injured more than 60.
The train was rounding a riverside curve in the Bronx when it came off the tracks.
The Metropolitan Transportation Authority says three men and one woman were killed. Authorities say three of the dead were found outside the train, and one was found inside.
Gov. Andrew Cuomo says the track didn't appear to be faulty, leaving speed as a possible culprit for the crash.
Officials say Sunday's accident is the second passenger train derailment in six months for Metro-North, and the first passenger death in an accident in its nearly 31-year history.
Meanwhile, Amtrak, whose trains run along the same rail line, has restored service between New York City and Albany, N.Y., but it says delays can be expected.
