AKRON, Ohio — The National Transportation Board is opening a special investigation Tuesday into the safety practices of one of the nation’s largest railroad corporations following several accidents, including last month’s toxic train derailment and the death of a train conductor.

Citing “the number and significance of recent Norfolk Southern accidents,” the NTSB said on Tuesday it will begin a broad look into Norfolk Southern’s “organization and safety culture.” The investigation will be the first of its kind within the rail industry since 2014.

The NTSB said it has deployed investigative teams to five significant accidents involving Norfolk Southern since December 2021. Three of the incidents were in Ohio in just over one month this year.

The board also urged the company to take immediate action to review and assess its safety practices, with the input of employees and others, and implement necessary changes to improve safety. 

The announcement comes the day after NTSB Chair Jennifer Homendy said a final report on the East Palestine, Ohio, derailment and hazardous materials spill could take more than a year to complete. Homendy has previously said the East Palestine derailment was “no accident” and that it was “100% preventable.”

Five significant accidents involving Norfolk Southern

The NTSB said it is concerned that several organizational factors may be involved in the accidents, including safety culture. In just over one year, the agency has sent investigative teams to five significant accidents:

  • On Dec. 8, 2021, an employee for National Salvage and Service Corp. assigned to work with a Norfolk Southern team replacing track was killed when the operator of a spike machine reversed direction and struck the employee in Reed, Pennsylvania. 
  • A Norfolk Southern trainee conductor was killed on Dec. 13, 2022,  and another conductor was injured, when the lead locomotive of a Norfolk Southern freight train struck a steel angle iron protruding from a gondola car on another Norfolk Southern freight train that was stopped on an adjacent track in Bessemer, Alabama. 
  • On Feb. 3, a Norfolk Southern freight train carrying hazardous materials derailed in East Palestine. The derailment resulted in a significant fire and hazardous materials release. 
  • A 2.55-mile-long Norfolk Southern freight train derailed near Springfield, Ohio, on March 4.
  • On March 7, a Norfolk Southern employee was killed during a train movement in Cleveland.
