How are railway tracks laid?

While preparing the track, long plates are laid beneath it. These are usually called sleepers. There are small stones beneath them, which are called blasters or ballast in common language. There are two layers of soil beneath the blasters. This is the reason why the railway track appears at a little height from the ground and when the train runs on the track, these stones, sleepers and blasters handle the weight of the train.

The science behind the stones

According to science, when a train runs on a track, it produces a kind of vibration. These pointed stones prevent the track from spreading due to the vibration. Let us tell you that if these stones are round, then they will not be able to stop the vibration and in such a case the track will spread. That is why pointed stones are laid on the track.

Tracks do not sink even in rain?

Apart from this, there is another specialty of these stones. Due to these stones lying on the tracks, no plants grow on the track. Due to which they do not obstruct the train. Due to these stones, the railway track is also high, so whenever there is waterlogging during the rainy season, the track does not submerge and the train keeps moving smoothly.
