The document summarizes the 2001 CSX 8888 incident which inspired the film Unstoppable. A runaway train traveled 66 miles through Ohio without a conductor at the controls. It was carrying thousands of gallons of the toxic chemical phenol. Attempts to derail it failed and shooting out the fuel valve also failed. For two hours the train sped up to 51 mph until a second train coupled and slowly applied its brakes, allowing a trainmaster to board and shut it down just southeast of Kenton, Ohio, avoiding injury.
