It's the most appropriate material for the task: strong, hard-wearing, smooth to reduce rolling friction without compromising adhesion; slightly elastic to help it bear very high, very rapidly changing stresses; relatively easy to manufacture to consistent high material and dimensional quality, and to form, join etc on site.
Really, there is no suitable alternative.

Why does the size of the gaps of a railway track expand on a hot day?
The size of the gaps between railway sections decreases on a hot day. This is due to thermal expansion. Nowadays different composites are used and different methods employed when laying track so 'continuous' rails may be laid.
What is the difference between in Normal speed railway track or High speed railway track are the rails of High speed railway track thick than Normal speed railway track?
Its not necessarily heavier (thicker is the wrong term), but it is more carefully aligned - and the curves are gentler.
Examples of effects of heat on matter?
Expansion, example the railway tracks. This is because when the metal expands on hot days, the track doesn't bends

What is a railway?
a railway is a track with engines it can be a mountain railway or just a railway * Added - A railway is a fixed guideway system (vehicles cannot leave the track) and can be powered by gravity, animals (including people), stationary engines, or locomotives (any vehicle that is self propelled).

As the term is used in conventional use today, a railway includes the track and all other wayside equipment, all the vehicles, stations, shops, and control centers.
Which metal is used to mend railway tracks?
The key element in railway lines depending on the railway line is, occasionally copper, magnesium and stainless steel.
What is rail gauge?
Rail gauge is the term used to measure the spacing of the rails on a railway track. This term is used in Australia. In the U.S., we use the term track gauge.
