WASHINGTON U.S. Senators Dick Durbin and Tammy Duckworth today called on U.S. Department of Transportation Secretary Elaine Chao to do more to prevent railroad tank car accidents like the one in Plainfield, Illinois on June 30, 2017, in which multiple rail cars on a Canadian National train carrying crude oil derailed, causing an estimated 45,000 gallons of oil to leak out of the tank cars. "We are extremely grateful for the hard work of Plainfield's first responders, who were able to contain the spill and prevent any injuries or deaths as a result of the incident," the Senators wrote in a letter to Secretary Chao.
