Since 1934, AAR has been the leading voice for the U.S. freight rail industry, driving policy, research, and technology to enhance safety and efficiency. Freight rail is a cornerstone of the U.S. economy, powering industries, facilitating trade, and supporting some of America’s safest and highest paid jobs—all while operating on a privately funded infrastructure that eases congestion on taxpayer-funded roads. From bulk commodities to intermodal freight, rail ensures the seamless movement of goods nationwide, serving as a vital link in global supply chains.
