During a hot summer mid day, if there was no gap between the two railway tracks then they would expand widely resulting into overlapping of tracks over each other. It is known that metals expand on heating that is on high temperature. The railway tracks expand greatly due to a high temperature and either overlap each other or form a circle or a roll like structure.
