Should blame be allocated to the engineer?  It was his job to keep the train at a safe speed. Right?   Was there a back up engineer?  How much blame goes to the back up engineer?   

Or should the blame be placed on the management?     The management knows that human engineers  have issues - heart attack, texting, stroke, two jobs, Germanwing syndrome - issues which will result in accidents that kill passengers.    

Long sections of the Northeast Amtak corridor already have Positive Speed Control as reported by the NYTimes here.    The safety technology is available and has been for decades.   

In my opinion, the management killed the passengers....
