CSX 8888 incident
In May 2001, an ordinary freight movement in Ohio turned into a pulse-pounding drama as a massive CSX train, dubbed the "Crazy Eights," became a runaway. Carrying highly flammable and toxic chemicals, it barreled through communities for nearly two hours, completely uncontrolled. How do you stop a 47-car, 50 mph freight train when no one is at the controls? The runaway began due to a series of specific human errors in brake application and throttle control, rather than a single mechanical failure. The train carried tank cars of molten phenol, a highly dangerous chemical, elevating the stakes of the high-speed, uncontrolled journey. The incident was resolved through an unprecedented mid-chase coupling of another locomotive to the runaway train, allowing its dynamic brakes to slow the train down.

The Crazy Eights Incident
On May 15, 2001, a routine day at CSX's Stanley Yard in Walbridge, Ohio, quickly escalated into a high-stakes emergency. Locomotive #8888, an EMD SD40-2, was tasked with moving a string of 47 freight cars—22 of them fully loaded—within the classification yard.
Among the loaded cars were two tank cars carrying thousands of gallons of molten phenol. This isn't just any industrial chemical; phenol is highly toxic, causing severe chemical burns upon contact and immense harm if ingested. Its presence turned a potential railway mishap into a public safety crisis.
A Critical Error
The locomotive engineer noticed a misaligned track switch ahead. With the tracks damp from recent rain, he realized his slowly moving train wouldn't stop in time to avoid it. A quick decision was made: he'd climb down, manually align the switch, and then reboard the locomotive.
Before exiting the cab, the engineer applied the locomotive's independent air brake. Crucially, he did not apply the automatic air brake, which would have set the brakes on every single car in the train. For intra-yard movements, the train's air brakes were often disconnected from the locomotive, making them non-functional in this state.
To complicate matters further, engaging only the independent brake also disabled the locomotive's 'dead man's switch.' This crucial safety feature is designed to automatically apply emergency brakes and cut engine power if the operator becomes incapacitated or leaves the controls. With it disengaged, there was no failsafe.
The engineer's biggest misstep involved the dynamic brake. He intended to engage it to slow the train to a crawl. Dynamic brakes work by using the train's momentum to drive the traction motors like generators, effectively turning kinetic energy into electricity and slowing the train—similar to regenerative braking in an electric car.
However, he "inadvertently failed to complete the selection process" for the dynamic brake. On older EMD locomotives, this involved a separate lever. Instead of setting the dynamic brake, he inadvertently left the throttle in a powerful accelerating position—notch 8. Without the dynamic brakes engaged, and only the locomotive's independent brake active, the powerful engines began to accelerate the train.
The Train Escapes
Having aligned the switch, the engineer tried desperately to reboard the now accelerating locomotive #8888. He was dragged for about 80 feet, sustaining minor injuries, before being forced to let go. The "Crazy Eights" was now a truly runaway train, hurtling out of the yard and beginning an uncontrolled 65-mile journey south through northwest Ohio.
Authorities quickly mobilized, attempting various desperate measures to stop it. A portable derailer was placed on the tracks, but the force of the speeding train simply threw it aside. Police even tried to shoot at the fuel cutoff button to starve the engine of diesel, but mistakenly hit the fuel cap, and even if they hadn't, the button needed to be held for several seconds to work.
The Pursuit
With ground efforts failing, a daring plan was conceived: a chase. A northbound freight train, Q636-15, was redirected to a siding. Its crew, engineer Jess Knowlton and conductor Terry L. Forson, uncoupled their locomotive, CSX #8392, and began to chase the runaway.
The goal: catch up, couple to the rear of #8888, and use #8392's dynamic brakes to slow the entire train. It was a risky maneuver, requiring precision and courage as both trains sped down the same track.
Knowlton and Forson successfully coupled onto the runaway train's final car. They then carefully applied #8392's dynamic brakes, creating resistance against the runaway's engines. Slowly but surely, the train's speed began to drop.
Once the train slowed to a mere 12 miles per hour, CSX trainmaster Jon Hosfeld, running alongside the moving train, bravely climbed aboard. He navigated to the cab of #8888 and finally shut down its engine, bringing the dramatic chase to a safe halt just southeast of Kenton, Ohio. Every brake shoe on #8888 was completely burned off from continuous, ineffective application throughout the ordeal.
Aftermath and Legacy
CSX never publicly named the 35-year veteran engineer whose string of errors initiated the incident, nor were the specific disciplinary actions taken against him ever disclosed. However, the event highlighted critical training gaps and safety protocols.
The incredible true story of the CSX 8888 incident served as the direct inspiration for the 2010 blockbuster movie, 'Unstoppable,' starring Denzel Washington and Chris Pine, bringing this nail-biting railway drama to the big screen.
What Happened to #8888?
Despite its infamous past, locomotive #8888 continued its service. In 2015, as part of a CSX refurbishment program, it was rebuilt and upgraded into an SD40-3 model.
The locomotive received a new cab and a new identity: #4389. Though it may look different, the engine that once ran wild on Ohio's tracks is still working hard today, a testament to its durable design—and perhaps a quiet reminder of that unforgettable day.

CSX 8888 incident
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, was pulling a train of 47 cars, including two cars loaded with hazardous chemicals, specifically molten phenol, a substance used in dyes and glues, and ran uncontrolled for just under two hours at up to 53 miles per hour (85 km/h). It was finally halted by a railroad crew in a catch locomotive, which caught up with the runaway train and coupled their locomotive to the rear car.
As of April 2026, the locomotive is still in service, having been rebuilt and upgraded into an SD40-3 as part of a refurbishment program carried out by CSX in 2015, although its number is now #4389 and it has a different cab. It was delivered as Conrail #6410 in September 1977.
Timeline
CSX 8888 incident
On May 15, 2001, a CSX locomotive engineer was using Locomotive #8888 to move a string of freight cars from track K12 to track D10 for departure on another train at Stanley Yard in Walbridge, Ohio, CSX's primary classification yard for Toledo. The string consisted of 47 freight cars; 25 of them were empty, but 22 of them were fully loaded, including two tank cars containing thousands of gallons of molten phenol, a toxic ingredient used in the production of many things including plastics, epoxies, nylon, numerous pharmaceutical drugs, detergents, and paints. It causes severe chemical burns upon direct skin or eye contact and is exceedingly harmful when ingested.
The engineer noticed a misaligned switch and concluded that his train, although moving slowly, would not be able to stop short of it, because the tracks were damp from rain. He decided to climb down from the train, correctly align the switch, and reboard the locomotive.
Before leaving the cab, the engineer applied the locomotive's independent air brake. During mainline operation, he would also have applied the automatic air brake, which would set the brakes in each of the train's cars. But, as is normal for intra-yard movements, the air brakes of the train were disconnected from the locomotive and thus were not functional. Furthermore, applying the locomotive's brakes disabled the train's dead man's switch, which would otherwise have applied the train brakes and cut the engine power.
The engineer also attempted to apply the locomotive's dynamic brake to slow the train to a crawl; dynamic brakes dissipate momentum (kinetic energy) by using the momentum of the train to drive the traction motors, generating electricity like a regenerative braking system does in a hybrid or electric automobile, which slows the train. However, the engineer "inadvertently failed to complete the selection process", meaning that he in effect set the train to accelerate, not to brake. Using the power throttle handle, the throttle for the traction motors was set at notch 8. If the dynamic brakes had been properly engaged as intended, the locomotive would have used the motors against the momentum of the train as generators, causing it to slow down. Instead, the train began to accelerate. The way he could make this mistake is because the dynamic brake system in the EMD locomotives of the time had a second lever to select the dynamic brake with three positions: "off", "set-up", and "brk/brake". To apply the dynamic brakes, the engineer would need to re-apply the throttle with the selection lever in the "brake" position. Without the dynamic brakes engaged, the only functioning brake was the air brakes on the locomotive, and this was not enough to counteract its power.
A portable derailer
The engineer climbed down from the cab, aligned the switch, and then attempted to reboard the accelerating locomotive. However, he was unable to do so and was dragged by #8888 for about 80 feet (24 m), receiving minor cuts and abrasions. The train rolled out of the yard and began a 65-mile (105 km) journey south through northwest Ohio unmanned. Attempts to derail the train using a portable derailer failed; the portable derailer was thrown off the track by the force of the train when struck. Police officers tried to starve the engine of diesel fuel and shut it down by shooting at the red fuel cutoff button, when three shots mistakenly hit the larger red fuel cap. This ultimately had no effect, because the buttons on former Conrail SD40-2s (like CSX #8888) must be pressed for several seconds before the switch is activated. A northbound freight train, Q636-15, was directed onto a siding where the crew uncoupled its locomotive, CSX #8392 (another EMD SD40-2), and waited for the runaway train to pass. #8392 had a crew of two: Jess Knowlton, an engineer with 31 years of service; and Terry L. Forson, a conductor with about one year's experience. Together they chased the runaway train. An EMD GP40-2, CSX locomotive #6008, was prepared farther down the line to couple to the front of the runaway to slow it further, if necessary.
Knowlton and Forson successfully coupled onto the rear car and slowed the train by applying the dynamic brakes on the chase locomotive. Once the runaway had slowed to 12 miles per hour (19 km/h), CSX trainmaster Jon Hosfeld ran alongside the train, climbed aboard, and shut down the engine. The train was stopped at the Ohio State Route 31 crossing, just southeast of Kenton, Ohio, before reaching locomotive #6008. All the brake shoes on #8888 had been completely burned off by the heat, since they had been applied all throughout the runaway trip.
CSX never made public the name of the 35-year veteran engineer whose error caused the runaway, nor what disciplinary action was taken.
