On Feb. 3, 2023, a Norfolk Southern freight train carrying hazardous materials derailed after a railcar's wheel bearing overheated, causing a fire. Three days later, officials conducted a "controlled release" of several tank cars that were filled with vinyl chloride, a toxic and flammable gas that can cause certain cancers, to prevent an explosion.

Every time Gregory Mascher hears a train whistle or one roaring through his small town, he said he is reminded of the fiery, toxic train derailment that happened two years ago.

A new lawsuit alleges for the first time that people died because of the disastrous 2023 East Palestine, Ohio, train derailment.
