Let Us Know Why Ballast Is Put Under The Railway Track

When railway tracks are laid, they are always laid on top of sleepers.
Which prevent the tracks from spreading here and there and also maintain the distance between them.
Earlier they used to be made of wood, but since the felling of trees has been banned, they have started being made of RCC (Reinforced Cement Concrete).
If these sleepers are placed directly on the ground, they will be pressed down by the weight of the train passing over them, then after the wheel is released, the sleepers will rise up.
When the top of the sleeper moves up and down, the ground and the air that comes in contact with it also keeps on expanding.
By continuing like this, the air will start taking out the particles of the ground in the form of dust and the sleeper will keep sinking down.
To prevent this collapse of the sleeper, large boulders of stone are used, which act as a cushion between the ground and the sleeper.
That is, first the ballasts bear the load. Then comes the number of land.
In a few days, these ballasts start coming out and the sleeper starts standing on the ground.
When such a situation arises, the ballasts are then put under the sleeper. This work happens from time to time.
Since the ground also has to bear some pressure along with the ballasts, then the ballasts go down in the ground, then more ballasts are called and put there.
This is how these ballasts work.
