U.S. investigators have recovered a data recorder, video recorder and the engineer's cellphone from the front car of the New Jersey train that crashed last week in Hoboken, N.J., killing one person and injuring more than 100.
The commuter train crashed last Thursday after it entered the Hoboken terminal during morning rush hour. Officials haven't determined the cause.
National Transportation Safety Board investigator James Southworth said it is not known if the recorders contain any useful information, but they have been sent to lab for analysis.
Investigators estimate the commuter train was traveling two to three times the 16 kph (nearly 10 mph) speed limit when it crashed, a U.S. official told The Associated Press on Tuesday.
Engineer Thomas Gallagher, who was at the train's controls, has been interviewed but said he has no memory of the crash, said T. Bella Dinh-Zarr, the vice chair of the NTSB.
Gallagher, 48, said he only remembered waking up on the floor of the engineer's cab, Dinh-Zarr said.
