Increasing population and high population density of India have put intense pressure on existing railway track. They are operating at a way more than their capacity, and this has strained many rail lines which lead to derailment and other mishaps. This high population density suits high-speed railway in the country. To fight with increased traffic with regard to speed and loading, the stresses variation in various components must be known accurately to evaluate useful life of each component for its life assessment. To assess, this detailed analysis is necessary to develop methodology for every track component under actual loading condition. In this paper, a comprehensive study of the behavior of ballastless track structure for high-speed train under static load has been carried out. For the analysis, three-slab track model has been developed which are simple track model, standard track model, and shinkansen track model. Deflection and stresses are the parameters which are used to analyze the performance of track system. Different track structures are analyzed under stationary wheel loads using finite element method of analysis. The influence of various parameters, i.e., change in material properties of track components on the behavior of track structures, is also investigated.
