| 摘要： | On January 16, 2007, at 8:43 a.m. Eastern Standard Time (EST), a northbound CSX Transportation, Inc. (CSX) freight Train Q50215, consisting of four locomotives and 80 freight cars, derailed 26 cars. The accident occurred near Shepherdsville, Kentucky (KY) at CSX milepost (MP) 15.12 on the CSX Mainline Subdivision, Louisville Division. The train was traveling at a recorded speed of 47 miles per hour (mph) when the 15th through the 40th cars from the locomotives derailed while traversing a 0 degree, 49 minute curve to the right, which had a super elevation of 1 inch. Twelve of the 26 derailed cars were tank cars containing hazardous materials. Seven tank cars were punctured or breached releasing Cyclohexane, Methyl Ethyl Ketone, and Butadiene in amounts ranging from small leaks to complete loss of contents. The derailment produced a fire ball, fire, and heavy smoke. Local emergency responders established an emergency evacuation radius of one mile. An estimated 500 area residents were either evacuated or sheltered-in-place and a local elementary school with about 400 students was closed. There were 36 people and two emergency responders who reported injuries that were treated and released at local medical facilities. No railroad employee injuries were reported. Track and equipment damages are estimated at $1,059,089. At the time of the accident, it was daylight with cloudy skies and a northwest wind of 16 mph. The temperature was 28F. A contributing factor in the accident is the broken body side bearing bolt at the BL position of AN 5696. The probable cause of the accident is the failure of the B truck of the 18th car (AN 5696) in the train consist to properly slew, causing the R1 wheel to climb the high (west) rail in the curve at MP 15.12 and derail to the field side of the west rail. |
