Norfolk Southern is seeking to hold GATX and OxyVinyls financially responsible for a $600 million settlement related to a 2023 train derailment in East Palestine, Ohio, which released toxic chemicals. The trial will determine liability, as Norfolk Southern argues that both companies share responsibility for the incident, while GATX and OxyVinyls maintain that Norfolk Southern was solely responsible for safety and operational decisions. The outcome will not affect the settlement amounts for affected residents, who are still awaiting payments amid ongoing appeals.
