On May 27, 2002, a Canadian National train derailed at 12:30 p.m. just north of Vermontville Hwy. in the City of Potterville. The train was hauling a total of 58 cars. Thirty-five of the cars derailed. Eleven of those cars contained hazmat material. Nine were carrying propane and two cars carried sulfuric acid. Two of the propane tankers were leaking and a third was suspected of leaking. Each propane car contains 34,000 gallons of propane gas which is considered an extreme fire and explosive hazard. An evacuation of the City of Potterville was declared. Canadian National along with many other agencies worked throughout the week to clean the area.
