In this Aug. 8, 2012 photo, DOT-111 class rail tankers travel through Council Bluffs, Iowa. For two decades, DOT-111 rail tankers, workhorses of the American rail fleet, have been allowed to haul hazardous liquids from coast to coast even though transportation officials were aware of a dangerous design flaw that almost guarantees the car will tear open in an accident. The rail and chemical industries have committed to a safer design for new tankers, but they do not want to modify tens of thousands of existing cars. That’s despite a spike in the number of accidents. (AP Photo/Nati Harnik)
