NTSB Investigator: ‘Nothing at All’ Heard From Amtrak Train Engineer Communications to Suggest Train Hit by Projectile

The idea an object hit the train is something that the NTSB is investigating.

“We interviewed the dispatchers and we listened to the dispatch tape, and we heard no communications at all from the Amtrak engineer to the dispatch center to say that something had struck his train,” Sumwalt said during an interview with ABC News' George Stephanopoulos on “This Week.”

“Nothing at all,” Sumwalt said.

Sumwalt said that the idea that an object hit the train is something that the NTSB is continuing to assess.

Following the crash, the Federal Railroad Administration ordered Amtrak to take steps to improve safety on the Northeast corridor.
