2023 Ohio train derailment

A train derailment occurred on February 3, 2023, at 8:55 p.m. EST (UTC−5), when 38 cars of a Norfolk Southern freight train carrying hazardous materials derailed in East Palestine, Ohio, United States. Several railcars burned for more than two days, with emergency crews then conducting a controlled burn of several railcars, which released hydrogen chloride and phosgene into the air. As a result, residents within a 1-mile (1.6-kilometer) radius were evacuated, and an emergency response was initiated from agencies in Ohio, Pennsylvania, West Virginia, and Virginia.
