Bridge troubled before derailment
A Paulsboro, N.J., bridge where a train derailed last week, releasing a hazardous chemical into the air, had a series of rail alignment problems leading up to the derailment, the National Transportation Safety Board’s top official said Monday. Some of the problems were reported the day before Friday’s derailment. A thorough inspection of the bridge and the derailed cars must wait until crews can remove all vinyl chloride from the area. That work, too, paused Monday when vinyl chloride detected in the air nearby twice reached an unsafe level.
