The U.S. Department of Transportation on Wednesday proposed a two-year phase-out of older railroad tank cars used to transport crude oil, which have been involved in several serious derailments over the past year. Officials in California and Sacramento applauded the move by the federal transportation agency. But some local leaders say they want the federal government to be do more. On Sunday, July 20, 2014, more than month after a train derailment in Buhl, Ala., several tank cars that were carrying fuel oil remain on their sides near people's homes.
