NEW YORK -- Federal investigators say the cars from a derailed New York City train will 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.
The train was rounding a riverside curve in the Bronx when it derailed, killing four people and injuring more than 60. A chain of toppled cars trailed off the track just inches from the water.
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.
