Association of American Railroads

The Association of American Railroads (AAR) is an industry trade group representing primarily the major freight railroads of North America (Canada, Mexico and the United States). Amtrak and some regional commuter railroads are also members. Smaller freight railroads are typically represented by the American Short Line and Regional Railroad Association (ASLRRA), although some smaller railroads and railroad holding companies are also members of the AAR. The AAR also has two associate programs, and most associates are suppliers to the railroad industry. Creation AAR was created October 12, 1934, by the merger of five industry-related groups: The American Railway Association The Association of Railway Executives The Bureau of Railroad Economics The Railway Accounting Officers Association The Railway Treasury Officers Association William George Besler was its first President.

Its applications support railroads, equipment owners and rail industry suppliers along every link of the supply chain.
