Of foremost importance in the railways is the maintenance of the substructure. Inadequate substructures can lead to track degradation system,

A railroad track substructure basically has four components, the
ballast,

and
subgrade.

Role of Geosynthetics in the railway sector: Whether it is new track construction or rehabilitation, there is enormous use of geosynthetics like geogrids, geocomposites, geocells, and geotextiles in the railway sector. Geotextiles
