The American Association of Railroads issued a rare advisory Thursday calling for certain rail cars to be taken out of service and inspected amid concerns that loose wheels might increase the risk of derailments.
The industry group said one of its railroads had experienced three loose wheels in the cars. The cars in question had wheels that were mounted between August of last year and March by National Steel Car, an Ontario-based rail car manufacturer, according to AAR. It said that any cars, loaded or empty, that are found to have these wheel sets must be removed immediately from service.
