HOBOKEN, N.J. - Federal investigators trying to determine the cause of last month's deadly train crash in New Jersey on Thursday released their first preliminary report.
The report from the National Transportation Safety Board stems mainly from the event and video data recorders recovered from the front of the train last week.
They indicate about 40 seconds before the September 29 crash, the train went from 8 mph to about 21.
That's more than double the speed limit for the Hoboken Terminal.
One person was killed in the crash and more than 100 others were injured.
The recordings also confirm the train's engineer, Thomas Gallagher, hit the emergency brakes less than one second before the crash.
Gallagher maintains that he was going the correct speed limit.
He told investigators the train was running about six minutes late.
He says he does not remember the crash itself.
Crew members have had blood and urine samples taken for toxicology tests.
Investigators say they're also trying to determine if mechanical issues are to blame.
