AI Summary
5 min readOn May 12, 2015, Amtrak Northeast Regional train 188 entered a 50 mph curve at Frankford Junction in North Philadelphia at 102 mph. The locomotive stayed upright, but the first coach wrapped itself around a 100-year-old catenary pole. Eight people died. Forty-six were critically injured. The engineer, Brandon Bostian, survived with a severe concussion and no memory of the crash. The NTSB determined the cause was a momentary loss of situational awareness: Bostian had been distracted by radio chatter about kids throwing rocks at trains, and he mistakenly believed he had already passed the curve. But the crash was entirely preventable. The technology that would have automatically slowed the train—Amtrak's Advanced Civil Speed Enforcement System (ACES)—was already installed on the track.
