Have you ever wondered why railway track are surrounded by stones?

Everyone loves to travel in a train,
isn’t that so? It’s an exhilarating experience all in all. The best part of
travelling by train is you get the chance to view the spectacular panoramas of
nature, extensive fields, metropolises brimming with people, or boundless expanses
of land with no sign of any existence whatever.

Another thing that we all usually notice
in our journey is those small stones lying along with the track on which your
train runs, right? Have you ever wondered as to why these stones are laid beside
a railway track?

Scroll to discover the real fact:

Track Ballast

To begin with, the pebbles that you see lay near to the railway tracks are collectively known as the track ballast. It is fundamentally the track bed on which the railway sleepers are placed. Track ballast is filled between the sleepers, in the parts underneath, and on the edges of railway trails. Well, most of you must be pondering what exactly do I mean by the term sleepers here?

A railway sleeper is a quadrilateral support that is generally kept at right angles to the tracks. Sleepers are called by a few other names too, like a train track tie or a crosstie. These are typically made of wood or pre-tensed concrete, even though the latter is more extensively used today. The prime purpose of railway sleepers is to embrace the rails vertically and appropriately spread out.

Why Specifically Those Pebbles?

It’s not at all like that the construction people come in and place just any shape and size of pebbles they find around the tracks. Well, that’s not the reason at all. These are special pebbles that are put around the track. Use of smooth and round pebbles in the ballast is avoided as chances are they might roll or slide over each other when a train runs over the track, thereby failing the real purpose– providing unanimity to the tracks. Given that fact, they make use of sharp and edged stones in the ballast so as to guarantee that the stones stay intact in the place. Amazing, huh?

Is That All Track Ballast Does?

In actual fact, the track ballast resolves a quite few number of purposes. First of all, it ensures that tracks stay in position when super-heavy trains run on them at a very high speed. It also plays a contributory role in keeping a check on the growth of any sort plants or shrubs around the tracks (and makes the ground underneath the tracks feebler).

Another important facet of track ballast is that it encloses the area to prevent entering of water around the tracks on a regular basis. That doesn’t mean the ballast totally shields the tracks from water, which would be difficult, but it does simplify water drainage around and underneath the tracks, so that water doesn’t sojourn near the tracks and compromise the cohesion of the ground.

An innovative technique to minimize vibrations

The too much use of railway lines for conveyance poses a risk to the constructions in the zones near the tracks as a result of the massive tremors the tracks go through when a high-speed train runs over them. In addition, the loud uproar that is formed when a train runs in a fast speed and even the tracks are the main reason behind annoyance to the neighbouring areas.

With the purpose of minimizing these tremors, a fairly simple compressing technique is engaged with the use of a dynamic tremor absorber. It comprises of EPDM or Ethylene Propylene Diene Monomer rubber due to its high resistance to high temperature, water, and other machine-driven pressures. Therefore, the pulsations are abridged to a great extent and the clamour is also lessened to a bare minimum.

Spread the right word of mouth

Many people or children usually pick up these pebbles and toss them around. If you are doing so, then believe me throwing these stones from around the tracks on a nice, sunny day is not the best way to get rid of the annoyance you’re facing or playing around!

Now that you completely understand why there are shingles on the train tracks, SHARE this post with your friends and family, so as to make them well aware about this amazing fact!
