Why Are There Gaps Between Railway Tracks : Useful Links
Small gaps which function as expansion joints are deliberately left between the rail ends to allow for expansion of the rails in hot weather. European practice ...
Solution: The gaps left between successive rails on a railway track, the reason is that the rails expand in summer. The gap is provided to allow for this expansion.
At each joint there must be a short gap (≈ 1/8″) between the rail ends, to allow for longitudinal thermal expansion of the rails on hot days. Fishplate joints are ...
