Welcome

The AAR's Technical Services group of committees are responsible for the development, maintenance, and enforcement of North American railroad interchange rules, mechanical standards, and component specifications that promote an acceptable level of safety and efficiency. Users of these publications include North American Class I, shortline, and regional railroads, Federal Railroad Administration, Transport Canada Railway Safety Directorate, private railcar owners, shippers, and freight car, locomotive, and component suppliers.

Committees members include railroad and non-railroad experts in the areas shown in the accompanying organization chart. These technical experts provide direction on the development and maintenance of industry standards. Committee Managers are located either at the AAR offices in Washington, D.C., or at the Transportation Technology Center, Inc., a subsidiary of the AAR located in Pueblo, Colorado, 21 miles northeast of Pueblo Airport.

Technical Services staff members manage at least one committee and are responsible for:
