The railroad said it promised to lead this effort to learn from the aftermath of its disastrous derailment as part of its settlement with the federal government. The NTSB will hold a hearing Tuesday to discuss what caused the Feb. 3, 2023 derailment and how to prevent similar derailments in the future.

More than three dozen railcars came off the tracks that night and piled up in a mangled mess of steel with 11 tank cars breaking open and spilling their hazardous cargo that then caught fire.

NTSB Chair Jennifer Homendy told Congress earlier this year that didn't have to happen. She said experts from the company that made the vinyl chloride, OxyVinyls, were certain that the feared chemical reaction that could have caused those tank cars to explode
