Why the gaps are left between rails on a railway track

Answers

Answered by Radhikakumari8112003

So that there is enough margin for the tracks to expand and contract due to the temperature changes. If that gap is not left then the tracks might have enormous stress in them while expanding due to heat. ... Thermal expansion of long continuous sections of rail tracks is the driving force for rail buckling.
