| 摘要： | At 5:00 a.m., May 28, 2006, northbound (timetable) UP train symboled MWCRV-26 (Train No. 1) traveling at a recorded speed of 40 mph, derailed 9 cars at a switch located at the south end (geographic) of Mojave in Mojave, California, mile post 381.4. The train was operating on the UPs Los Angeles Division, Mojave Subdivision under centralized traffic control by the UP dispatcher in Omaha, NE. The locomotives and head end of the train traversed a switch from single main track to double main track, Main Track 2 when the derailment occurred while the train was moving. Freight car CHTT 273637 derailed along with eight other cars on the switch to main track 2. As a result, the locomotives and the head portion went on Main Track 2 while all cars following CHTT 273637 went to Main Track 1 until the train stopped, blocking both Main Tracks 1 and 2. One of the derailed cars raked the second locomotive of an unoccupied UP train RMJLVC-26 (Train No. 2), which was sitting in yard track 1, adjacent to Main Track 1. There were no injuries to the crew of Train No. 1 and no hazardous materials were involved. The weather was clear, visibility was dark and the temperature was 51 degrees Fahrenheit. Damage was estimated at: equipment, $173,424; track and signal, $392,604. The probable cause is Unusual Operational Situations, interaction of lateral/vertical forces (includes harmonic rock off). |
