• the American Railway Association,
• the Association of Railway Executives,
• the Bureau of Railroad Economics,
• the Railway Accounting Officers Association, and
• the Railway Treasury Officers Association.

One of the AAR's duties is to oversee the assignment of reporting marks – two to four letter codes that uniquely identify the owner of any piece of railroad rolling stock or intermodal equipment (trailers, containers, etc.) that can be carried on a railroad. The AAR also classifies railroads into Class I, Class II and Class III based on income.
