Investigators say the operator hitting the brakes too fast caused last November’s train derailment that spilled 20-thousand gallons of ethanol into the Mississippi near Alma, Wisconsin — just across the river from Wabasha. The report says the 112-car train was southbound at 26 miles an hour when it jumped the tracks. No one was hurt, but B-N-S-F says track and equipment sustained over two million dollars in damage.
