NTSB holds 2-day hearing on East Palestine toxic train derailment

The National Transportation Safety Board will start taking sworn testimony Thursday as part of its probe into the toxic train derailment in East Palestine, Ohio.

The agency is holding an investigative hearing on Thursday and Friday in East Palestine, where a Norfolk Southern Railway train carrying toxic chemicals derailed on Feb. 3, resulting in the release of hazardous materials into the air, soil and creeks in the area.

A preliminary NTSB report released in the weeks following the incident found that a wheel bearing failed moments before 38 cars derailed in the incident -- including 11 tank cars carrying hazardous materials that subsequently ignited.
