"OMAHA, Neb. — Federal investigators are opening a wide-ranging investigation into one of the nation’s biggest railroads following a fiery derailment on the Ohio-Pennsylvania border last month and several other accidents involving Norfolk Southern, including the death of a train conductor Tuesday.
The National Transportation Safety Board said on Tuesday it will begin a broad look at the company's safety culture — the first such investigation within the rail industry since 2014. The NTSB said it has sent investigation teams to look into five significant accidents involving Norfolk Southern since December 2021.
The agency also urged the company to take immediate action to review and assess its safety practices."
