Question

Why are gaps left between successive rails on a railway track?

Answer 1

1. Steel rails are used to construct railway tracks.
2. A slight space is left between the two subsequent lengths of rails when installing the railway track.
3. The reason for this is that in the summer, the rails expand.
4. The space is left open to allow for this expansion.
5. If no spacing is left, the rails will bend sideways due to the expansion in the summer and this could lead to a train accident.
