WASHINGTON — In the wake of a Norfolk Southern derailment in Springfield, Ohio, railroads should take certain new steel coil cars out of service until their wheelsets can be replaced, the Association of American Railroads says.

“Yesterday, Norfolk Southern identified loose wheels on a series of cars that presents an increased risk of an out of gauge derailment. Today, AAR through its committee structure, took expeditious action and has issued an advisory to stop cars with these wheels from use and interchange until those wheel sets can be replaced,” AAR spokeswoman Jessica Kahanek says.

“This is an uncommon defect to see in a wheelset that demanded urgent action. This is a voluntary, proactive step aimed at ensuring equipment health and integrity,” she adds.

The advisory affects about 625 cars manufactured by National Steel Car of Hamilton, Ontario, Canada.

Twenty-eight cars of a Norfolk Southern train derailed near Springfield on Saturday evening. NS said the 212-car train was en route from Bellevue, Ohio, to Birmingham, Ala. Video shot at a grade crossing and posted online showed an NS steel coil car apparently initiating the derailment.

The cars in question were built between August 2022 and March of this year, according to the AAR advisory.

The derailment in Springfield was among the incidents that prompted the National Transportation Safety Board and Federal Railroad Administration to launch separate probes of Norfolk Southern’s overall safety practices.

In a statement, NS said: “During Norfolk Southern’s cleanup of the derailment in Springfield, Ohio, on March 5, the company determined that a specific model and series of railcars had loose wheels, which could cause a derailment. The investigative team identified these wheels as coming from a series of recently acquired cars from a specific manufacturer. Although the investigation into the cause of the accident is still underway, we immediately notified the National Transportation Safety Board and the Federal Railroad Administration and began inspecting other cars from this series on our network.

“Upon identifying additional cases of unusual wheel movement, we acted swiftly. We issued orders to remove these cars from service until their wheelsets could be replaced, and we have taken steps to remove this specific model and series from service until they can be fully inspected. We also notified the manufacturer and worked urgently to inform the rest of the railroad industry, as Norfolk Southern is not the only user of these cars. As a result, the Association of American Railroads issued an advisory to halt the use of these cars. Norfolk Southern will continue to investigate this matter and take appropriate action.”

10 thoughts on “AAR urges railroads to sideline new cars that may have caused NS derailment in Springfield, Ohio

  1. This wheel slipping problem may take a lot of testing and detective work.
    1. Is the metal content and location(s) the same as in past wheel and axel combinations?
    2. Have any of the procedures boring and axel machined of axel and wheels changed?
    3. measurements changed even a 1000th inch or less ?
    4. Change of equipment processing axels and wheels ?
    5. Change of pressing temps ?
    6. Did wheel / axels ever had keyways ?
    7. Just this builder ?
    8. Could this extend to other newly built cars.?

    Any application to passenger train cars or locos ?

    1. Add
      9. what temps are they joined together and for how long at those temps?
      10. Allowed to cool or quick drenching ?

  2. Yes, Mr. McFarlane, I did know that, but in my 70 years I had never heard of wheels shifting on the axles until this last year. What’s happening now?

  3. The article quotes people who use wheelsets and wheels interchangably. They are not the same. So what is the problem? Individual wheels becoming loosened on their axle or wheelsets becoming misaligned in their truck frames?

  4. How many other Railroads have trucks and wheel sets from NSC built in those 6 months or before or after?

    1. R Messera…you do know that freight cars and transit vehicles DO NOT use they same type of wheels and axles, don’t you?

    2. Yes Mr McFarlane But are they made by the same Manufacture? I would think that they don’t just make wheel sets for transit vehicles. Would like to see if they were made not to gauge or they moved on the axle.

    3. NSC assembles the complete truck with components from multiple suppliers. They press the wheels onto the axle in their truck assembly shop.
      Hopefully his is not another case of metric to imperial measurements gone wrong.
