Photos: A look at the aftermath of the Ohio train derailment

It's been more than a week since about 50 cars of a freight train derailed in a fiery, mangled mess near the Pennsylvania state line. In the days since, residents' concerns and questions have only abounded — amplified, in part, by misinformation spreading online.

The head of the EPA got a first-hand look Thursday at the damage and emotional toll left by a freight train derailment in Ohio that spilled toxic chemicals and burned in a huge plume over homes and businesses.

Long before this month’s fiery derailment, railroad industry leaders battled regulations meant to boost freight train safety, including plans to bolster some of the very same tank cars that ruptured and released chemicals in eastern Ohio.

In a packed Senate hearing, CEO Alan Shaw claimed his railroad firmly supports the goal of improving rail safety.

Fear and mistrust still grip many in the village of 4,700 whipsawed by government assurances that the air and water are safe.

Anonymous pro-Russian accounts started spreading misleading claims and anti-American propaganda about it on Twitter.

The federal government filed a lawsuit against railroad Norfolk Southern over environmental damage caused by a train derailment on the Ohio-Pennsylvania border that spilled hazardous chemicals into nearby creeks and rivers.

Federal regulators say railroads need to re-examine how they assemble their trains. The call comes after a string of derailments in recent years that were partly caused by the way empty and loaded cars were mixed together with locomotives.

Officials in southeastern Michigan were angry when a landfill and deep-injection wells near Detroit received contaminated soils and liquids from a train derailment in East Palestine, Ohio.

Residents of East Palestine, Ohio say they worry what will happen to them and the village where they have deep family roots, friendships and affordable homes.
