Gravel: Ballast laid around the railway tracks

Pieces of stone are laid around Ray Lave's tracks. As the vehicle passes over the tracks, the tracks tremble with its roar. Gravel is laid around it to prevent this shaking.

Pebbles also have to be placed between the wooden sleepers under the rails. This is well known. These stones are called ballasts. Ballasts are 1.5 inches to two inches thick. This measure is maintained. That is, they are almost identical in size. As the train passes, you notice that the pebbles are trembling. That is, he has absorbed the tremors of the band. Around the band, there is a 4 inch thick layer of ballast under the band and below it there is another 5 inch layer of small gravel and then there is soil.

So ballast is not only a stone but also an important part of railway engineering. This piece of stone is obtained by first sifting through a 6 inch perforated grazing and then by sifting through a 1.5 inch perforated grazing.
