(CNN) – More details about the Sunday’s Metro-North commuter train derailment in the Bronx have been released.
The National Transportation Safety Board is investigating the incident that led to four deaths and dozens of injures.
Just after 7 a.m. Sunday, the train was heading towards Grand Central Station, but ten miles north of Manhattan, it came to this curve. All seven passenger cars and the locomotive derailed.
The NTSB revealed new details on Monday, from event recorders recovered from the train.
“The train was traveling at approximately 82 miles per hour as it went into a 30 mile an hour curve,” NTSB Board Member Earl Weener said at Monday’s press conference.
The curve calls for a reduction in speed from 70 miles per hour to 30. The conductor says he applied the brakes, but the train did not slow down.
In July, only 1700 feet away, there was a similar incident. A freight train also derailed around the same bend.
For now, investigators say it’s too early to pin this tragedy on human error or faulty equipment.
