Why are there so many stones on the railway tracks?

Friends, you may have traveled by train at some point, but have you ever wondered why there are so many stones under the railway tracks? Or why these stones are not used for anything else?

So there are two reasons for this.

First of all, friends, you have to understand that the railway tracks are not as easy as they seem. If you look closely at the railway line, you will see rectangular blocks of cement between the two rails, called sleepers. And the stones you see with this sleeper are called ballast.

When you look at the tracks of a railway, you will always feel that the tracks of the railway are laid on a simple ground. But to be honest, it’s not that easy. The railway tracks we see have two more layers of soil beneath them and the ground beneath them, so the railway trucks are always a little higher than the ground. And the cement sleeper between the rails and a lot of stones around it hold the two rails together and do not leave a gap between the rails.

Friends, the weight of a train is about 10-15 lakh kg, so you may think that a thin iron


track cannot carry that much weight. Therefore, the rails, sleeper blocks and side stones are a major contributor to the weight of the train.

In fact, the highest load of the train is on the rocks around the track. And these stones help to keep the railway tracks in one place.

But no stones are used under the railway tracks. Angled and rough stones are mainly used here, so that these stones get stuck in each other and hold the track tight. And because of this the train runs comfortably on the railway tracks no matter how heavy or fast the train is.

Another use of these stones is that if the stones are not placed under the railway tracks, a lot of trees are likely to grow around the railway tracks, so these stones do not cause grass or other trees to grow on the tracks. Also, these stones do not collect rain water on the sides of the track.
