The courts long debated whether Bostian should face a jury. Special Agent Brian Julien testified that the federal government declined to bring charges against Bostian.
Former Philadelphia District Attorney Seth Williams also passed on the case, saying “we cannot conclude that the evidence rises to the high level necessary to charge the engineer or anyone else with a criminal offense.”
The Pennsylvania Attorney General’s office took up a private complaint filed on behalf of victim’s and their families, and in 2020, the Pennsylvania Superior Court ruled that the case could go to trial.
Judge Barbara McDermott ruled that the jury could only hear evidence that speaks to Bostian’s “state of mind” at the time of the incident. They were not permitted to hear information about Amtrak’s liability, and technology installed after that could have prevented the derailment.
Witnesses for the prosecution testified to the destruction the derailment caused.
The business class car looked like “a can that was ripped open from the middle,” testified Philadelphia Police Officer Craig Perry.
The derailment crushed passenger Blair Berman’s heel bone, and broke her elbow. When she came to after the accident, “I tried standing up and I collapsed,” she told jurors. She testified that she did physical therapy every day for two years as a result of her injuries.
Senior deputy attorney general Christopher Phillips also called several witnesses to show that Bostian’s training, and experience, meant he should have kept his train on the track.
Rock-throwing incidents are common and train engineers must memorize the speed changes and visual landmarks along their route in order to be certified, testified Keith Strobel, who trains locomotive engineers. The two trains actually struck by objects that night, SEPTA 769 and Acela 2173, did not derail.
“Despite knowing where he was, Frankford Curve, he accelerated for 33 seconds,” Phillips told the jury during closing arguments.
Defense attorneys Brian McMonagle and Robert Goggins argued that Bostian was only “human.”
“Do engineers sometimes make mistakes?” they asked Jonathan Hines, Assistant Superintendent of Terminal Operations at Amtrak.
“Yes,” said Hines.
The defense argued that the rock-throwing incidents that night were “unusual,” as were the lengthy radio broadcasts about whether or not the engineer of SEPTA 769 needed medical attention.
“Situational awareness is learned,” said Wilbur E. Wolf III, who testified as an expert witness for the defense. Amtrak was negligent in not better preparing its engineers for how to maintain it, he said.
