The NJ Transit crash in Hoboken Thursday morning that killed one person and injured over 100 others has raised questions about how it could have been prevented.
Officials say none of NJ Transit's trains are equipped with Positive Train Control, a safety system designed to prevent accidents by automatically slowing or stopping trains that are going too fast in certain situations. The nation's railroad industry is under government orders to install PTC, but the deadline has been repeatedly extended.
Peter Haynes, executive director of the LIRR Commuters Campaign, says PTC would not have made any difference in this situation since the train was at the end of the track.
"The engineer has the full responsibility to actually bring the train to a stop," says Haynes.
The NTSB says it is working to find the cause of the crash.
