Federal investigators say they have recovered one of the "black boxes" from the commuter train that hit Hoboken Terminal in New Jersey on Thursday, as they work to discover why the train struck the terminal at a high speed.
The crash killed a woman and injured more than 100 people. The accident also caused structural damage to the century-old train station.
PATH trains and some New Jersey Transit trains have resumed service, but some rail services are still suspended, NPR's Hansi Lo Wang reports.
