The National Transportation Safety Board has released its report regarding an oil-train derailment and fire in Custer, Wash. NTSB officials said Thursday their report focused solely on how the derailed tank cars performed in the crash. Ten tank cars derailed and five caught fire in Custer on Dec. 22. No injuries were reported. But the NTSB report said dozens were evacuated and about 29,000 gallons of crude oil were discharged. The report said nine of the 10 derailed cars had been enhanced to industry standards. Earlier this week, KUOW reported that a railroad union official called the derailment sabotage. The FBI has yet to release the results of its investigation.
