 Right before the fatal derailment of Amtrak Train 188 a conductor said she believes she heard the engineer say that a window on the train had been "struck by something," National Transporation Safety Board member Robert Sumwalt said Friday. "She heard him talking to a SEPTA engineer who reported to a train dispatcher that he had either been hit by a rock or shot at," Sumwalt said, "and that the SEPTA engineer said he had a broken windshield and put the train into an emergency stop." Sumwalt said that officials also had spoken with a conductor who "believes she heard her engineer say something about his train being struck by something," Sumwalt said. Bostian was interviewed Friday afternoon for the first time since the derailment of Amtrak Northeast Regional Train 188. In the agency's final briefing in Philadelphia on Tuesday night's horrific accident, Sumwalt said the FBI now was involved in the investigation of the crash that killed eight people and injured 200. Bostian was accompanied by his attorney, who has said his client suffered a concussion in the crash. He said the right-hand side of the windshield was shattered by the crash impact. Sumwalt said the particular damage that NTSB wants the FBI to examine is the circular pattern of damage on the lower left windshield, as seen from inside the engineer's station. He said the damage appeared in a "circular pattern that emanates out quite a bit." It was not known when NTSB agency would release a final report on the crash of Train 188. Under questioning, "he demonstrated very good working knowledge of the territory" where the derailment occurred, including speed limits at various points along the route between Washington and New York, which he made five days a week. — Alfred Price (@TheAlfredPrice) May 13, 2015 
 
 Scott Knowles, another passenger on the SEPTA train, said the incident happened somewhere between Philadelphia's 30th Street station and the North Philadelphia station. It also has forced 12,000 daily riders who use SEPTA's Trenton Line to find alternate routes to work and has prevented NJ Transit's Atlantic City line trains from getting to and from 30th Street Station. In a statement, Amtrak president Joseph Boardman said, "Amtrak takes full responsibility, and deeply apologizes for our role in this tragic event."
– The feds have interviewed the Amtrak engineer at the controls before this week's crash in Philadelphia, and while Brandon Bostian was fully cooperative, he says he still can't remember a thing about the derailment, reports CNN. But the more interesting development came from an interview with an assistant conductor, who said she thought she heard Bostian say before the crash that the train's windshield had been "broken by something,” reports the Philadelphia Inquirer. “We have seen damage to the left-hand lower portion of Amtrak windshield that we have asked the FBI to come in and look at for us,” says NTSB board member Robert Sumwalt. Prior to the crash, two other trains in the area had been hit by some kind of projectile, reports the Inquirer. One was a Southeastern Pennsylvania Transportation Authority train, and the assistant conductor remembers hearing about it. "She recalled that the SEPTA engineer had reported to the train dispatcher that he had either been hit by a rock or shot at, and the SEPTA engineer said that he had a broken windshield, and he placed his train into emergency stop," says Sumwalt. "She also believed that she heard (the Amtrak) engineer say something about his train being struck by something." As for Bostian, he told the NTSB that he hadn't been sick or tired, but insisted he remembers nothing beyond the point his train left the nearby station in north Philly. (The train was clearly speeding up before entering a curve at twice the speed limit.)
