NEW YORK CITY -- The National Transportation Safety Board released its preliminary report on the December fatal train derailment in New York City.
The Metro-North train derailed in the Bronx, and killed four people and injured dozens more. According to the NTSB, the onscene work has been completed, and the rest of the investigation will continue at its Washington headquarters.
In the report, investigators estimated the train was traveling at 82 miles per hour inside a zone limited to 30 miles per hour. There were no mechanical problems or issues with the signal system that may have resulted in the crash. There were also no issues with the physical track.
Data recorders from the train are still being analyzed in Washington. The NTSB says its plans to release interviews with the train crew and first responders once they are available.
