A major train crash that took place in North Jersey could have been caused by sleep apnea. Officials are saying this could have played a role in the accident. The AP was the first to report the story. A 34-year-old woman died in the crash and over 100 people were injured in the crash that took place at the Hoboken train station. Thomas Gallagher was the train operator and had worked for 18 years with New Jersey Transit.
