HOBOKEN, New Jersey --The National Transportation Safety Board says the NJ Transit train that crashed at Hoboken Terminal was going 21 m.p.h., twice the speed limit, at the time of the accident.
The details were downloaded from the event data and forward-facing video recorders on a NJ Transit commuter train.
Federal investigators also say the train's engineer hit the emergency brake less than a second before the crash.
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.
Meantime the damaged commuter train was removed from the terminal.
It isn't known when service will be restored at the terminal.
