A high-speed train is one which often operates at a speed above 200 kmph (125 mph). High-speed trains bring about new challenges in the construction of strong railway roadbeds so as to protect mechanical components of trains and track structures from damage, to improve the comfort of riding for passengers and to reduce ground vibration and noise pollution. While designing railway tracks, irregularities of the wheels and rails must be accounted for, as they may induce considerable dynamic loads. For a track structure, the most important part is a concrete sleeper. There is a continuous need for the improvement in the analytical tools for the dynamic analysis of the concrete sleepers. A 3D FEM model of the concrete sleeper is developed in SAP2000 version 18.0 software considering two conditions, that is, when sleeper is placed on-site without any constraints and when it is placed on ballast. The results obtained are finally validated with the previously done work on STRAND7 software by comparing their mode shapes.
