Amtrak has activated an integral train safety system on rail lines connecting New York and Philadelphia. As of Monday, December 21, all tracks owned by Amtrak in the Northeast Corridor are equipped with Positive Train Control (PTC), a collision avoidance and speed control system.

Roughly 57 miles of track connecting New Haven, Connecticut and New Rochelle, New York do not have PTC, according to Amtrak officials, because that section of track is owned by Metro-North.

On May 12, 2015, an Amtrak train derailed at a curve in North Philadelphia, killing eight people and injuring over 200 others. Amtrak train 188 approached the curve at Frankford Junction going 106 miles-per-hour, more than double the posted speed limit in the area. Amtrak engineer Brandon Bostian hit the emergency brake, but it was too late—the locomotive and all seven passenger cars left the tracks.

Caleb Bonham, a founding partner of a Denver, Colorado-based corporate and political public relations consulting firm, was one of the 238 passengers aboard Amtrak 188. He remembers the seats of the train shaking before he was violently thrown about the passenger car.

Bonham is one of many passengers to file an Amtrak lawsuit in the wake of the Philadelphia train crash. He and six other passengers are represented by Baum, Hedlund, Aristei & Goldman.

Investigators from the National Transportation Safety Board (NTSB) have said the Amtrak crash in Philadelphia would not have happened if PTC had been implemented on that particular section of track. PTC had been implemented in Massachusetts, Connecticut, New Jersey, Maryland and Delaware.
