Update: A judge arraigned Brandon Bostian late Thursday night and released the Amtrak 188 engineer on bond ahead of future court hearings.
Brandon Bostian, the engineer operating Amtrak 188 when it derailed in Northeast Philadelphia two years ago killing eight passengers and injuring 200 others, surrendered to police Thursday on manslaughter charges.
Philadelphia Police handcuffed Bostian on the sidewalk as he arrived at Central Detectives in the city's Fairmount section around 10 a.m. The 33-year-old Somerville, Massachusetts, resident remained silent, looking straight ahead and his attorney offered "no comment at this point."
Bostian faces eight counts of involuntary manslaughter, one count of causing or risking a catastrophe and numerous counts of reckless endangerment.
Pennsylvania Attorney General Josh Shapiro charged Bostian Friday, a mere seven hours before the statute of limitations was set to expire in the case, and following a legal challenge by the family of a woman killed in the derailment.
Amtrak 188 was traveling 106 mph when it jumped the northbound tracks negotiating the curve at Frankford Junction on May 12, 2015. Several cars overturned and one was left crushed and contorted. The curve's speed limit was 50 mph.
Eight passengers were killed and 200 were injured. Bostian told investigators he couldn't remember the moments leading up to the crash. He suffered a blow to the head during the derailment.
The case was transferred to Shapiro's office on Thursday after Philadelphia Municipal Court President Judge Marsha Neifield ordered a private criminal complaint could move forward.
Philadelphia District Attorney Seth Williams previously declined to file charges against the engineer. After Williams' office denied charges, the family of Rachel Jacobs filed a private criminal complaint in Philadelphia Municipal court. A judge ruled Bostian should be charged and the case was referred to Shapiro's office.
"I commend our outstanding team in the Office of the Attorney General who worked diligently and thoughtfully around the clock to enable us to be in this position to pursue justice on behalf of the victims of this deadly crash," Shapiro said in a statement.
An intense federal investigation focused on what Bostian was doing in the moments leading up to the derailment.
Investigators with the National Transportation Safety Board said Bostian accelerated to full-throttle as the New York-bound train traversed a straightaway through North Philadelphia.
The NTSB analyzed the engineer's cellphone to determine whether he was distracted by the device. They found it had been turned off before and during the incident. It was later ruled that radio chatter about a rock strike to a nearby SEPTA train's windshield stole Bostian's attention that night.
He lost track of where he was on the route; the realization that the curve was looming ahead in the darkness didn't come until seconds before the crash, investigators said. Bostian hit the brakes right before he felt the train tipping over.
"I remember holding onto the controls tightly and feeling like, okay well this is it, I'm going over," Bostian told investigators. He said he remembered speeding up and later hitting the emergency break, but nothing in between.
When the engine and the six cars in tow left the tracks near Wheatsheaf Lane around 9:15 p.m., passengers were tossed like dolls in the carriages. The first passenger car hit steel support beams suspending electrical wires. The beams sliced through the car, bending the coach into an unrecognizable shape. Some passengers were ejected from the train through broken emergency windows and were crushed.
Eight passengers died: Derrick Griffith, 42, a dean at Medgar Evers College in Brooklyn, New York; Rachel Jacobs, 39, the CEO of Philadelphia-based company ApprenNet and a mother of a toddler; Abid Gilani, 55, who worked for Wells Fargo; Justin Zemser, 20, a Naval Academy midshipman; Jim Gaines, 48, a father and Associated Press video software architect; Bob Gildersleeve, 45, a father and vice president of Ecolab; Laura Finamore, 47, a senior account director at Cushman & Wakefield; and Giuseppe Piras, 41, a wine and oil executive from Sardinia, Italy.
Two hundred other passengers were hurt with injuries ranging from paralysis to broken bones and scratches. Police, firefighters and nearby homeowners helped to carry the injured from the tracks to waiting ambulances and buses. Those who could walk were offered water and a place to sit inside stranger's homes.
Amtrak agreed to a $265-million settlement with the injured and families of those killed. Bostian also filed suit against Amtrak in January, accusing the railroad of not providing him a safe working environment.
The railroad came under fire after the catastrophe for not having a speed control system on the rails. Called Positive Train Control, the system will automatically slow a train that is speeding. Amtrak later said the system was installed on the tracks, but not activated. It has since been deployed.
Bostian has not spoken publicly about the derailment in the two years since. The NTSB investigation said he was a train enthusiast who had good knowledge of the speeds and tracks he was operating on.
Two trains operating on the same route were struck by flying rocks that night — a SEPTA Regional Rail train and an Amtrak Acela heading for Philadelphia's 30th Street Station. Passengers on the Acela shared pictures of a shattered window with NBC10 following the derailment.
Experts theorized that Amtrak 188's locomotive could have also been hit by a flying rock, the impact of which may have disoriented Bostian, but the engineer's memory loss and a lack of additional evidence left the hypothesis unproven.
