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 member programs, and most associate members 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Association of American Railroads」の詳細全文を読む スポンサード リンク
