The response to the CSX 8888 incident on May 15, 2001, was a high-stakes, real-world "action movie" scenario that required incredible coordination between railroad staff and local law enforcement. When the unmanned train, carrying hazardous molten phenol, escaped the Toledo yard, officials first tried to use portable derailers, which the heavy locomotive simply crushed. Police then attempted to shoot the emergency fuel cutoff switch on the side of the engine, but were unsuccessful. The turning point came when a second "chase" locomotive, led by engineer Jesse Knowlton and conductor Terry Forson, caught up to the runaway from behind and successfully coupled to it. By applying their own dynamic brakes, they were able to slow the train from 51 mph to about 12 mph. This allowed CSX trainmaster Jon Hosfeld to physically run alongside the moving train, climb aboard, and shut down the engine. The incident led to immediate changes in railroad safety protocols, including stricter "dead-man's switch" requirements and improved training for yard operations to prevent a locomotive from ever being left in power without a crew member present.
