A train tank car dangles from a crane as it is pulled up from the crash site on a small bridge on the Mantua Creek, Tuesday, Dec. 11, 2012, in Paulsboro, N.J. The tank car was the first to be removed as officials continued to clean up after the accident. Hazardous gas spewed from a ruptured freight train car during the accident, which occurred Nov. 30, 2012. Precautionary evacuations were ordered late after readings showed higher levels of vinyl chloride in the air. (AP Photo/Julio Cortez)
