WASHINGTON, June 25 (Reuters) - The National

Transportation Safety Board opened a meeting Tuesday to

determine the probable cause of a February 2023 Norfolk Southern ( NSC )

train derailment in East Palestine, Ohio and make

recommendations to boost rail safety.

The derailment forced residents to temporarily abandon their

homes after the train caught fire and released over a million

gallons of hazardous materials and pollutants near the state's

border with Pennsylvania. Last month, Norfolk Southern ( NSC ) agreed to

pay a $15 million civil penalty and $57.1 million in past

government cleanup costs, as well as millions in future costs to

resolve a U.S. government lawsuit.
