Over the last few years, a need for high speed locomotives for faster connectivity between cities in India has been recognized due to its superior economic, social and environmental benefits in comparison to other comparable means of transport. Given the background, safety and endurance become a vital need of the hour since it calls for a shift from conventional design, execution and maintenance approaches as regards High – speed locomotives. So, with an objective to ensure safety of the passengers, longevity of the infrastructure and minimize the impact of vibrations; we need to safe guard the mechanical components of trains and tracks from any such damage. Innovative approaches are required in the design and construction of strong railway roadbeds based on accurate modelling of the force induced and the corresponding impact on the track foundation caused by the high-speed trains at speeds exceeding 300 kmph as against the current conventional designs which cater to design speeds of up to – 180 kmph. In the captioned study plastic settlement of CL type of track foundation soil is computed at a point subjected to various magnitude of cyclic loading grounded on the method as put forward by Li and Selig.
