The gaps between rails allow for expansion from heat. The space for expansion prebents buckling.
It depends which gaps you mean! Older track was laid in discrete sections with gaps left between them to allow for expansion on hot days. There are gaps between rails at the points which are used to connect different tracks together in turn. Is this what you mean?
Railway tracks are laid with gaps between the ends to accommodate thermal expansion and contraction of the metal. When temperatures rise, the steel tracks expand, and without gaps, this could lead to buckling or warping. Conversely, during colder temperatures, the tracks contract, and the gaps ensure they remain properly aligned and safe for trains to travel over. This design feature is crucial for maintaining the structural integrity and safety of the railway system.
If rails were laid in long sections with no gaps between them, thermal expansion could cause significant issues. As temperatures rise, the metal would expand, potentially leading to buckling or warping of the rails. This could create dangerous conditions for trains, as the track may become misaligned, increasing the risk of derailments. To prevent these problems, railways typically include expansion joints or gaps to accommodate thermal changes.
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.

The steel rails may expand due to the heat, causing the tracks to buckle or curve up. This can lead to derailments and damage to the tracks. It is important to leave gaps between rails to allow for expansion and contraction due to temperature changes.
For heat expansion.
Railways work by using a system of tracks, locomotives, and freight or passenger cars to transport goods or people from one place to another. The locomotive provides the power to pull the train along the tracks, which are laid on a continuous bed of crushed rock or gravel called the ballast. Signals, switches, and control systems help to regulate the movement of trains along the railway network.
because when train comes in high speed it expands a little.for this reason railway tracks are laid
There is clearly a great advantage in railways being on the same gauge. Rolling stock can be moved seamlessly offering interoperability between railway companies.In 1846 the United Kingdom Parliament looked into this matter and, although Isambard Kingdom Brunels' pioneering gauge was 7ft 1/4 inch, there were more tracks that were laid on the gauge of 4 ft 81/2inches. Consequently, the Gauge Commission were in favour of the latter which was then adopted by act of Parliament.There is clearly a great advantage in railways being on the same gauge.

Sleepers, many of the sleepers on modern track are being replaced with concrete sleepers.
- MRT and Railway tracksif a continuous track of metal is used, it will expand in hot weather and bent. trains running on bent tracks may be derailed. to prevent this, railway tracks are laid in sections with expansion gaps between them. A sliding joint between adjoining rails allows them to expand without bending.- bridgesboth concrete and steel bridges are built with allowance for expansion and contraction due to changes in the surrounding temperatures. Rollers and sliding joints allow for the movements of the bridges as it expands and contracts
