Abstract: In this paper, the main factors in the analysis of the railway concrete sleepers are investigated and new recommendations are made in order to improve the accuracy of the current practices in analysis of the railway track system. First, a comprehensive literature survey is conducted, then, FEM models for a railway track system are developed and used to discuss and evaluate the assumptions commonly used in the analysis of the railway track system. The analysis factors investigated include stress distribution under a concrete sleeper, rail-seat load, and dynamic coefficient factor. Finally, recommendations and needs for continuation of the research are presented.
