On January 25, 2006, about 10:15 p.m. Central Standard Time (CST), Burlington Northern Santa Fe (BNSF) southbound Train M MEMBIR1-24 consisting of five locomotives, 66 loads, and 20 empty cars derailed 30 cars at milepost (MP) 693.5 at Jasper, Alabama (AL). The train was operating on the Springfield Division, Birmingham Subdivision originating at Memphis, Tennessee (TN) with an intermediate crew change point at Amory, Mississippi (MS) and a final destination at Birmingham, AL. The train crew consisted of a locomotive engineer and conductor. They reported for duty at BNSF Yard in Amory, MS at 10:35 a.m., on January 25, 2006, having 25 hours 15 minutes of rest. The train departed Amory Yard at 11:52 a.m., and was 6,099 feet in length with 9,066 trailing tons. The engineer said descending the first grade after departing Amory, the train experienced a run-in while operating in dynamic braking. He made adjustments at the next grade by going into dynamic braking earlier and the train did not experience another run-in until prior to the accident. The engineer said the rear of his train had just cleared the 30 miles per hour (mph) speed restriction when he felt buff forces shove the train forward. He continued reducing dynamic braking and placed the dynamic brake handle to set-up position. Then, an undesired train line emergency brake application occurred. At the time of the derailment, the train was being operated at 30 mph. BNSF reported $311,794 car damage, $250,000 track damage, and $75,000 bridge (decking) damage. There were no hazardous material cars in the train, no injuries, and no evacuation ordered. At the time of the derailment, it was dark, the weather was clear, and the temperature was 36 oF. The probable cause is train make-up, code H599. Contributing factors to the accident: a combination of track curvature, grade, number of cars with hydraulic cushioning units, and number of locomotive dynamic brake axles, code M599.
