Question

no gaps are left between the rails of railways tracks​

Answer 1

Answer:

The gap is left between the rails to provide a space for the iron metal to expand and contract during the summer and winter season due to the change in the temperatures. If the gap is not left in between then the rails will bend more and cause derailing of the trains.
