NEWARK, N.J. — The Latest on the investigation into last week's crash of a New Jersey Transit train at the Hoboken Terminal (all times local):

4:10 p.m.

Federal investigators say a New Jersey Transit train that crashed into Hoboken's terminal was going twice the speed limit at the moment of impact. They also say the train's engineer hit the emergency brake less than a second before the crash.The National Transportation Safety Board revealed the details Thursday. They were gleaned from data recorders aboard the train.

The speed limit for the station area is 10 mph.

The NTSB says the train was traveling at 8 mph and sped up for about 30 seconds before hitting 21 mph.

A final report on what caused last week's crash, which killed one person and injured more than 100, could take a year or longer to complete.

7:10 a.m.

New Jersey Transit is implementing a new rule for pulling into two of its stations a week after one of its commuter trains crashed into a terminal, killing a woman on the platform and injuring more than 100 others.

NJ Transit spokeswoman Jennifer Nelson says the conductor must join the engineer whenever a train pulls into Hoboken Terminal or its Atlantic City station. That means a second set of eyes will be watching as a train enters the final phase of its trip at stations where there are platforms at the end of the rails.

The New York Times first reported the policy.

The engineer was alone when the train crashed into the Hoboken station last Thursday. He's told federal investigators the train was entering the station at 10 mph, but he had no memory of the crash.
