Reasons Why Stones Are Always Placed Along Railway Tracks

In this post, I'll get to explain what these stones are and why they are usually located on railroad tracks. If you frequently travel by train or pass via a railway track, you'll get to notice certain stones that are put all along the route.

First off, according to, the stones you see being placed on railroad tracks are known as track ballast. This implies that the track ballast is often placed between the sleepers since it creates the trackbed on which the railway sleepers are laid.

You mention sleepers. The main purpose of a sleeper is to maintain the appropriate spacing of the track and to hold the rails upright. Sleepers are that rectangular support that is perpendicular to the track; they are often built of concrete or wood. Sleepers also go by the names crosstie and railroad tie.

According to an article published on, track ballast has several functions. The first is that it stabilizes the track by distributing the weight of the ties, which support the entire weight of the train on the track, allowing for thermal expansion, significant ground movement, and weight variance, which permits the passage of very heavy trains.

It should be noted that track ballast does not completely protect the tracks from water; rather, it simply facilitates water drainage around and below the tracks to prevent water from becoming stagnant and weakening the ground's integrity. Track ballast also aids in preventing the growth of any vegetation around the tracks and aids in sealing out any form of water that may harbour around the tracks and cause the metal to rust.

Additionally, sharp-edged stones are used to ensure that the stones stay in place since smooth or rounded stones may ultimately slide over one another as a train passes, defeating the goal of track ballast, which is to preserve ground unity.
