On March 8, a train pulling 80 tank cars of ethanol derailed in Providence, Rhode Island. Luckily, no ethanol was spilled and no one was injured. However, activists immediately began calling for a halt to these “unit trains” of ethanol into and out of the city, noting the potential risks to the community. Unit trains are longer than average freight trains — often 100 cars or more — dedicated to carrying a single commodity, such as ethanol or crude oil.
These risks were on display two days later when a unit train hauling 100 cars of ethanol derailed on a bridge in Graettinger, Iowa, approximately 160 miles from Des Moines. This time, 27 of the cars left the tracks. At least eight tank cars ruptured and caught fire, and three tank cars ended up in a creek beneath the bridge, releasing about 1,600 gallons of ethanol into the waterway.
