Federal safety investigators have recovered a data recorder, a video recorder and the engineer's cellphone from the front car of the commuter train that crashed in New Jersey last week.
National Transportation Safety Board investigator James Southworth says they don't yet know if the recorders contain any useful information. The instruments have been sent to an agency lab for analysis.
The lab also has the engineer's cellphone, which was found in a backpack in the cab of the front train car.
The NTSB already checked a data recorder that was in the rear of the train. That one wasn't functioning on the day of the crash.
A U.S. official says investigators estimate a commuter train was traveling 20 to 30 mph when it slammed into a New Jersey rail terminal last week.
The official was briefed on the investigation but wasn't authorized to speak publicly about it and spoke to The Associated Press on the condition of anonymity.
The official says federal investigators are basing the speed estimate on the extent of damage caused by the crash, which killed a woman and injured more than 100 people.
Investigators are working to access a device in the train that records its speed.
The Hoboken station's speed limit is 10 mph, and the engineer told investigators that's how fast the train was going.
The National Transportation Safety Board is expected to provide an update on the investigation late Tuesday afternoon.

Crews are continuing to work to recover a data recorder from a commuter train that crashed in New Jersey, killing a woman and injuring more than 100 others.
National Transportation Safety Board investigators have not yet been able to extract the recorder from the front car of a New Jersey Transit train that crashed into Hoboken Terminal on Thursday.
An NTSB spokesman says crews are working in 12-hour shifts to clear debris surrounding the train to ensure that it's structurally safe for investigators.
Officials have said a data recorder in the rear of the train wasn't functioning on the day of the crash. That recorder was supposed to store speed and braking information.
The NTSB has said the train's engineer told investigators that he has no memory of the crash.
