The CSX 8888 incident, also known as the Crazy Eights incident, was a runaway train event involving a CSX Transportation freight train in the U.S. state of Ohio on May 15, 2001. Locomotive #8888, an EMD SD40-2, ran uncontrolled for just under two hours at up to 53 miles per hour (85 km/h) while pulling a train of 47 cars; 2 cars were loaded with molten phenol, a substance used in dyes and glues. It was finally halted by a railroad crew in a catch locomotive, who caught up with the runaway train and coupled their locomotive to the rear car. The incident inspired the 2010 movie Unstoppable.
