A freight train derailed in East Palestine, Ohio, earlier this month, and the NTSB has released a preliminary report on the incident. The report identified that the crew did not receive a warning about an overheating axle until just before the derailment occurred, and the train was traveling 47 miles per hour at the time. The NTSB is continuing to investigate the cause of the derailment and to ensure similar incidents do not occur in the future.
