SUPERIOR, Montana — A train headed for Renton with Boeing parts derailed Thursday in Montana.
19 cars of the Montana Rail Link Train derailed — three of them had aircraft parts that fell into a river.
Boeing says the parts were on their way for final assembly for 737, 747 and 777 planes.
Seven of the cars that derailed were empty, three had soybeans and three contained denatured alcohol.
Officials are not sure what caused the train to go off the tracks. The train originated in Kansas City.
