See what I mean about our national infrastructure? This Conrail bridge already collapsed once before, in 2009: PAULSBORO, N.J. - November 30, 2012 (WPVI) -- A freight train derailed Friday on an old railroad bridge that has had problems before, toppling two tanker cars partially into a creek and causing a leak of hazardous gas that was blamed for sickening dozens of people, authorities said. Members of the National Transportation Safety Board arrived in New Jersey on Friday afternoon to investigate.
