Officials work the scene of derailed freight train tank cars in Paulsboro, N.J., on Nov. 30, 2012. People in three southern New Jersey towns were told Friday to stay inside after a freight train derailed and several tanker cars carrying hazardous materials toppled from a bridge and into a creek. At least one tanker car contained vinyl chloride, according to authorities.  / AP Photo/Mel Evans PAULSBORO, N.J. Conrail crews studied reported signal problems at a New Jersey railroad bridge the day before a train derailment that caused a toxic chemical leak, federal investigators said Sunday. More than 100 people remained out of their homes while crews hoped to start removing the hazardous material, vinyl chloride, from a ruptured tanker. The National Transportation Safety Board cannot examine the scene until the chemicals are removed.
