Question

Explain why rails have gaps at specific distance.​

Answer 1

Answer:

this is due to expansion and contraction of rails during winter and summer.

Answer 2

Answer:

All solids expand on heating. As rails are made up of steel, these also expand in summers and contract in winters. ... Thus, the rails have been provided with gaps at a specific distance so as to prevent this bending of rails. These spaces get closer in summers and wider in winters.
