Trains are considered as the main mode of transport in India. Whenever we look at railway tracks, we see small stones lying between and below the railway tracks.
But have you ever wondered why stones are laid on railway tracks and on both its sides?
After reading this article, you will find the answer to this question easily.
The Indian Railways carries around 25 million passengers daily to its destination. In addition, Indian Railways employs over 1.4 million people.
It is thus one of the largest employment donors in the world. Indian Railways has the fourth largest railway network in the world by size. As of March 2017, the total length of the track here was 121,407 km.
Reason for laying small stones between railway tracks
There is a scientific reason behind the laying of small stones between railway tracks. In the early stages, railway tracks were constructed with the help of steel and wooden rails,
But in today’s time’s rectangular blocks of cement are used instead of wooden rails, which are called “sleepers”.
In fact, the purpose of laying small stones between rail tracks is to keep wooden tracks or cement blocks firmly in place so that these blocks hold the rail tracks firmly.
Actually, when the train moves, it vibrates on the ground and tracks. In addition, the sun expands and shrinks the tracks in winter. It puts the entire weight of the train on a wooden or cement block,
But due to the laying of stones between the tracks, all the load goes on these stones, due to which the vibration, the shrinking of the tracks, the load of the train are all balanced.
Simultaneously, one of the reasons for laying stones between railway tracks is that when the heavy train passes through the railway track, its balance must be maintained and there is no damage to the ground.
In addition, the laying of stones between railway tracks makes the flow of rainwater easier and there is no mud on and between railway tracks. At the same time, the laying of stones between railway tracks also causes noise pollution.
One reason behind placing stones between railway tracks is that if stones are not planted, bushes will grow around the railway tracks, which will make the train difficult to pass.
For your information, we want to tell that Indian Railways is the fourth largest railway network in the world.
As per the data released at the end of 2015-16, the Indian railway network is spread over an area of 66,687 km and has 7,216 stations and 1,19,630 km of tracks.
