Rail track is the set of two parallel lines of long pieces of steel. It used on railway to guide trains without the need for steering. The structure is separated into two main structure elements such as substructure (subgrade and protection layer) and superstructure (ballast, sleepers, baseplates, fastenings and rails).
Rail track also supported by cross pieces set at regular intervals called sleepers which spread the high pressure load imposed by the train wheels into the ground (Kahawatta, 2019).
