Amtrak Derailment: Everything You Need to Know About the Crash of Northeast Regional Train 188

Philadelphia Mayor Michael Nutter said on Thursday that there have been eight confirmed deaths stemming from the derailment of Amtrak Northeast Regional Train 188.

All 243 people (238 passengers and five crew members) from the train have been accounted, for and 43 are still being treated at hospitals, according to BuzzFeed News.

The engineer of the train, 32-year-old Brandon Bostian of Queens, N.Y., and the conductor, who still has not been identified, survived the crash. Bostian's attorney told ABC News that the engineer "suffered a concussion" and has "no explanation" as to why the train derailed. Directly after the crash, Bostian did not provide an official statement to police when they inquired.

According to Bostian's LinkedIn page, he began working at Amtrak as a passenger conductor in 2006. Four years later, he became a passenger engineer.

The train's speed may have played a part in the crash, CNN reports:

"Initial data show the train barreled into a curve at about 106 mph, National Transportation Safety Board member Robert Sumwalt said. That's more than twice the 50-mph speed limit for the curve, and above the 80-mph limit immediately before it."

Eight to ten train cars left the tracks and so far, the number of passengers injured is at 50, but that number may climb as the fire department and search and rescue go car-to-car, according to NBC 10 Philadelphia.

Amtrak posted on Twitter that all services between New York and Philadelphia are cancelled. Amtrak also encouraged concerned family members of train 188 passengers to call Amtrak's Emergency Hotline at 800-523-9101.
