HOBOKEN, N.J.—Federal investigators are sifting through the wreckage of a train crash in New Jersey to determine what happened before it barreled through a station and crashed into a barrier, causing a young mother to be killed by falling debris and injuring more than 100 others.
Investigators from the National Transportation Safety Board will be looking to determine how fast the commuter train was going when it crashed at the busy Hoboken station Thursday morning.
Their investigation will seek to answer many questions, including whether a system designed to prevent accidents by overriding the engineer and automatically slowing or stopping trains that are going too fast could have helped if it had been installed on the line.
