NTSB: Norfolk Southern withheld information during East Palestine train derailment
After confirming on Tuesday the trackside detector failure, NTSB investigators also said that Norfolk Southern and its contractors compromised the integrity of the vent-and-burn decision by withholding accurate information from OxyVinyls, the company that made the vinyl chloride.
Norfolk Southern and its contractors botched the decision to blow open five vinyl chloride tank cars after last year’s disastrous derailment in East Palestine, Ohio, and trackside detectors that might have prevented the crash failed to accurately detect the temperature of a burning wheel bearing 20 miles (32.19 kilometers) beforehand, according to the National Transportation Safety Board.
