ABSTRACT: The Heavy Axle Load (HAL) implementation program began in 1988 with the objective of developing economically optimal and safe axle loads for North American railroads. This research is currently being conducted by the Transportation Technology Center, Inc. (TTC), a subsidiary of the Association of American Railroads (AAR), to examine the effects of increased axle loads on track and track components, subgrade, and structures, and to ensure that safe operations are not compromised as axle loads increase. The Tie and Fastener Test has been an integral part of the HAL program since its inception in 1988. This report compiles the results of tests that characterize the performance of cross ties under heavy axle loads. The program is sponsored by the AAR in partnership with the Federal Railroad Administration.
