On February 4, a train carrying hazardous materials provoked a fire and expelled toxic fumes into the air. Since the disaster, residents of East Palestine, Ohio, have complained of respiratory problems.

Initially, the cause of the derailment had not been released to the public, but recent reports have come out.

“A preliminary report from the East Palestine derailment, released Thursday by the National Transportation Safety Board, found hot box sensors detected that a wheel bearing was heating up miles before it eventually failed and caused the train to derail,” CNN said. “But the detectors didn’t alert the crew until it was too late.”

Local residents are still upset as they feel they are being prevented from knowing the truth about the disaster.

“Why are people getting sick if there’s nothing in the air or in the water?” East Palestine resident said.

Since the disaster, legal action has been taken against the train operator and company.

“Ohio environmental officials made a civil referral this week asking the state attorney general’s office to begin “legal and/or equitable civil actions” against train operator Norfolk Southern,” CNN said. “This could result in a civil complaint if negotiations with the company were to fail.”

Although civil action has taken place, it is not enough for local residents.

“It seems as if what rolls through on those tracks is of more value than the lives of the residents in this community.” East Palestine residents said.
