摘要: At 3:07 p.m., c.d.t., on June 27, 2006, eastbound CSXT Train Symbol S638-28 derailed 21 cars at milepost QS217.1, near Sant Jacobs, Illinois. This line segment runs from St Louis, Missouri, to Danville, Illinois, on the CSXT Great Lakes Division, St. Louis Line Subdivision. Saint Jacobs is located about 20 miles northeast of St. Louis. Train Symbol S638-28 consisted of 2 locomotives, 81 loads, 50 empties, 11,390 tons and was 7,969 feet long. The train was being operated at a recorded speed of 54 mph when the derailment occurred. Car numbers 79 through 99 derailed, which consisted of 17 loads and 4 empties. Seven derailed cars involved hazardous materials including three loads of ammonium nitrate, two loads of hydrogen peroxide and two residue cars which last contained dimethylamine and methylamine. Three loads of ammonium nitrate were ruptured and one load of hydrogen peroxide spilled product on the ground. The spill initiated a precautionary evacuation of 35 local residents and closed local roads within a 12 mile. The evacuation was lifted at 4:15 p.m., on June 28, 2006. Monetary damages were $614,319 for mechanical and $50,000 for track, for a total of $664,319. The probable cause of the derailment was a failure of the cross key retainer, which allowed the coupler to fall out of the A-end of Car No. CSXT 139356, the 79th head car. When the coupler fell to the track structure, it derailed one axle of Car No. CSXT 139356. The derailed wheels remained on the ties next to the rail for approximately 1,000 feet until it struck a road crossing. The road crossing caused the derailed car to steer to the north and cause derailment/pile up of the following cars.
