The New Jersey Transit commuter train that slammed into Hoboken Terminal last week was reportedly speeding at the time of the crash.
That's according to a U.S. official briefed on the investigation who spoke anonymously to The Associated Press.
But, asked about the speed of the train during a media briefing Tuesday, federal safety investigators said it's too early to make that determination.
"We're not prepared to make that statement right now," said a spokesman for the National Transportation Safety Board. "This is a fact gathering operation that we do here on the scene. There's a lot of information we have to look at and tear down. And that type of information is purely analysis and we don't do that on the scene."
The train's engineer told investigators he was doing the speed limit — ten miles per hour.
Crews have recovered a second data recorder, a video recorder and the engineer's cell phone from the first car of the mangled train.
34-year-old Fabiola Bittar de Kroon was killed in the crash and more than 100 others were hurt.
New Jersey Transit service in and out of Hoboken remains suspended indefinitely.
