Railways are a form of regular transport for millions of people in India, which makes it an integral part of transportation sector of our country. The modernization of railways is being carried out extensively in order to meet the ever increasing demands of the population. Geosynthetics are being widely used worldwide as a reinforcement material for various applications. Rail tracks are one of the most important and emerging areas where geosynthetics can be used to fulfill the various requirements of reducing track maintenance costs as well as track degradation due to excessive settlements. This paper attempts to investigate the improvement in geocell-reinforced railway tracks using three-dimensional finite element modeling over unreinforced tracks. The sub-ballast heights and modulus of geocell were varied using MIDAS GTS-NX, 2016 which is a commercially available finite element analysis software, to observe the effect of these parameters on the improvement in track-beds using geocell. The results of the FEM analyses indicate that the performance of rail tracks can be improved using geocell as a track reinforcement material.
