Association of American Railroads

The Association of American Railroads (AAR ) is the industry association of the great quality travel lanes of North America (Canada, Mexico and the United States). The Amtrak and some other regional railroads are also members.

The Association of American Railroads was taken on October 12, 1934 by the merger of five industry-related associations:

  • American Railway Association
  • Association of Railway Executives
  • Bureau of Railroad Economics
  • Railway Accounting Officers Association
  • Railway Treasury Officers Association

Headquarters of the Organization is Washington, D.C.

Reporting marks

One of the tasks of the AAR is the assignment of reporting marks - a code 2-4 letters that uniquely identifies the owner of the rolling stock, or to be transported container.

Classification

Furthermore, the AAR classifies railroads according to their size.

  • Class 1 = Railway with a turnover of more than $ 401.4 million
  • Regional Railroad = railway company which operates a distance of more than 350 miles and / or more than $ 40 million turnover (so-called class 2 according to the rules of the Surface Transportation Board)
  • Local Railroad (formerly Short Line Railroad ) = no " Class 1" - or " regional " train, but with commercial operation (so-called Class 3 according to STB)
  • Terminal and Switching Railroad ( Rangiergesellschaft ) = the railroad no point - to-point transport (scheduled ) performs, but the connection between end users and the other railway companies
