Abstract: This article presents the results of a survey in which 27 worldwide railroads addressed questions related to rail-wear limits by track class, methods used for measuring wear, rail sections and grades, tie types and spacings, rail defects and traffic information. The objective of the survey was to help determine methods for extending rail life. The article identifies the different types of stress in rails, such as contact, residual and thermal, and focuses on nominal rail-bending stress. Conclusions derived from the survey indicate that freight railroads worldwide have common track problems and seem to be converging on common track practices in dealing with rail stress.
