PHILADELPHIA (AP) — Prosecutors are set to argue that criminal charges should be reinstated against the engineer in a deadly 2015 Amtrak derailment in Philadelphia.

Pennsylvania's attorney general on Wednesday is appealing a judge's decision to dismiss the case against Brandon Bostian.

Eight people died when the Washington-to-New York train rounded a curve at more than twice the 50 mph (80 kph) speed limit and hurdled off the tracks. Federal safety investigators concluded Bostian was distracted by radio traffic and lost his bearings.

Philadelphia's district attorney previously declined to pursue a case against the 34-year-old engineer. A separate lawsuit brought by a victim's family was thrown out by a judge in September who said evidence suggested the derailment was accidental.
