Why Tiny Stones are Laid on Railway Tracks

Most of us have travelled using trains and have witnessed the existence of the tiny stones on the railway track.

They help keep the train tracks in place. The stones form the trackbed and are packed around railway tracks as well. These stones help keep the railway tracks upright and properly placed making it able to support the heavy trains as they pass.

The stones also facilitate proper drainage around the track hence preventing the ground on which the line runs through from becoming too moist and weak.
