A railroad industry trade association has recommended that railroads remove from service coil cars similar to those involved in a March 5 derailment of a Norfolk Southern train in Springfield, Ohio.
The Association of American Railroads made the recommendation, which it said affects about 675 coil cars from service recently built by National Steel Car of Hamilton, Ontario.
At least two of the cars were involved in the Springfield derailment.
In its announcement, the AAR said a defect in the cars may have caused horizontal movement as the cars were in motion. Investigators found loose wheels on two of the cars in questions involved in the Ohio derailment.
According to the AAR, the defect may have caused horizontal movement as the car traveled down the line. The AAR recommendation advises railroads to replace the wheel sets before putting them back into service.
“This is an uncommon defect to see in a wheel set that demanded urgent action,” AAR said in a statement.
The cars covered by the advisory were built between August 2022 and March 2023.
