Train derailments are common, but few reach the level of East Palestine crisis

When a train derailed in East Palestine, Ohio, earlier this year, it quickly led to national headlines. 

Locals were evacuated once it became clear that the 151-car train had been carrying hazardous chemicals, including vinyl chloride, and weeks later, those residents are still demanding answers on how a controlled release and burn of some of those chemicals may have affected the environment. 

Since then, almost every day has brought news of another derailed train.
