The 2023 East Palestine, Ohio derailment

Last year, on Feb. 3, one of Norfolks' trains derailed in East Palestine, Ohio near the Pennsylvania border.

Residents initially watched the fires from the crash and were later evacuated as officials feared a potential hazardous chemical explosion, and they executed the vent and burn.

National Transportation Safety Board officials have said an overheated bearing on one of the railcars likely caused the crash, but questions remained about whether that could have been prevented and whether officials made the right choice to burn off the vinyl chloride.

In June, the NTSB recommended Norfolk Southern revise its incident report about the derailment to reflect the vent and burn of vinyl chloride were not necessary.
