The Metro-North train that derailed on Sunday was reportedly going 82 mph as it was taking a 30-mph corner.
The National Transportation Safety Board announced the data showed the train was going way over the posted speed for the curve and even over the posted speed of 70 mph for the track ahead the curve, CNN reports.
NTSB member Earl Weener said that data from event recorders showed the engineer cutting the throttle six seconds before the train came to a rest and brakes were applied only five seconds before that. He said the action taken was "very late in the game."
Weener did note, "This is raw data off the event recorders, so it tells us what happened. It doesn't tell us why it happened." The engineer, William Rockefeller, and others on the crew were still answering questions on Monday.
As previously reported, the Metro-North commuter train jumped the track as it was going around a curve just 100 yards north of the Spuyten Duyvil station. Councilman G. Oliver Koppell called the accident "certainly the worst one on this line."
Four people were killed and over 60 people were injured from the crash. Many on the trail recalled the crash as surreal.
