Why are sleepers provided under the rail tracks?

Sleepers, or railway ties, are provided under rail tracks to support and maintain the alignment of the rails. They distribute the weight of the trains across a wider area, preventing the tracks from sinking or shifting due to the heavy loads. Sleepers also help to absorb vibrations and reduce wear on the tracks, ensuring a smoother ride and enhancing safety. Additionally, they provide stability against lateral forces, such as those generated during train movement.
