This file contains all AAR assigned reporting marks as of April, 1987. In the absence of AAR assigned reporting marks, "the AAR uniform Alpha code is given, designated with *. Reporting marks, along with the car serial number, are used by shippers and railroads to identify specific pieces of rolling stock. ALL organizations with cars in interchange service are assigned reporting marks by the AAR. Some reporting marks may still be registered even though the organizations no longer have cars in interchange service or may still be awaiting delivery of ordered, but not yet available, cars. The uniform ALPHA code is assigned by the AAR to all organizations that may be involved in handling rail equipment. The ALPHA code usually, but NOT always, is the same as the reporting marks and, in the case of an organization that has no current or planned interchange equipment, is NOT to be considered as reporting marks until so assigned. The ALPHA code is used by shippers and railroads to identify car-handling organizations for purpose of routing, billing, division of charges, etc. Please note that this file contains references to companies that are known to be no longer in existence.
