HOBOKEN, NJ (AP) – The National Transportation Safety Board revealed Thursday the train that crashed into the Hoboken, New Jersey, train station last week accelerated in the seconds before the crash.

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

The speed limit for the station area is 10 mph.

The information was obtained from data recorders aboard the train.

The engineer told federal investigators the train was entering the station at 10 mph, but he had no memory of the crash. Another engineer who witnessed the crash told local media the engineer on the train appeared to slump over as the train approached the station.

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.

New Jersey Transit is implementing a new rule for pulling into two of its stations.

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.
