HOBOKEN, N.J.—Here’s what is known about the investigation into a commuter train crash that killed one person and injured more than 100 others Thursday in Hoboken, New Jersey.

The Investigation

Federal investigators say there were no problems with signals at a New Jersey station where the commuter train crashed.

The National Transportation Safety Board said Saturday that the signals leading to the Hoboken Terminal appear to be working normally. It says a full study can’t be completed yet because the train is still in the station.

Officials say structural issues are preventing work crews from removing the New Jersey Transit train from the terminal.
