| 摘要： | A southbound UP freight train bearing Train Symbol SSSON-11 (Train No. 1) collided with another southbound UP freight train bearing Train Symbol MSSNP-11 (Train No. 2) on August 12, 2006, at 4:43 p.m. The accident occurred on UP single main track near Bradford, Iowa, milepost (MP) 157.5, on the Mason City Subdivision, Twin Cities Service Unit. There were no injuries. The impact caused the rear four cars of Train No. 2 to derail and the two locomotives and leading wheels of the head car of Train No. 1 to derail. Both locomotives of Train No. 1 remained upright with diesel fuel leaking from the lead locomotive's ruptured fuel tanks. Approximately 2,000 gallons of diesel fuel spilled and began to flow toward waterway Mayne Creek near milepost 157.6, approximately 10 car lengths to the north. Spill flow was stopped before reaching the waterway. The end-of-train device of Train No. 2 was destroyed in the collision. The three rear cars of Train No. 2 had all wheels derailed on the ground with the platforms crosswise to the main track. The fourth rear car of Train No. 2 (the rear end of a 5-pack platform) had all wheels derailed in the west ditch with the head end of platform wheels on the rails. The weather at the time of the accident was clear, daylight, wind SSE at 13 mph, and the temperature was 85F. The accident was caused by the failure of the crew of Train No. 1 to comply with signal indication requiring train to operate at restricted speed. |
