Do you know why there are stones on train tracks

These stones are not only placed as filling, but they serve a fundamental function. They are known as railway ballast and are composed of small fragments of rocks such as quartzite, basalt and granite, with a size of between 3 and 7 centimeters. Ballast helps distribute the weight of rails and trains, preventing ground from deformation and reducing the risk of derailment.

It also has the ability to absorb and dissipate vibrations generated by the passage of trains, preventing them from being transmitted over long distances. In addition, it allows water drainage, preventing potential flooding on the tracks. Its function is fundamental for the stability and safety of the railway system.
