Why are train tracks made of stone and pebbles?
Trains have always been one of the most popular means of transportation since their appearance, as they were characterized by their speed and the absence of congestion in their rails. Trains have known a great development since their first invention. After they used to work on coal and emit smoke, they are now powered by electricity only, but what has not changed so far is Its tracks and rails are still made of gravel. In your opinion, dear readers, why are train tracks made of stone and small gravel?
This is what you will know the answer shortly.
Railroad tracks are made of iron or steel and they extend for long distances, so that they are exposed to bad weather conditions such as rain and heat, which causes them to shrink and vibrations without forgetting that plants and weeds grow from below.
Without the gravel, the planks will not stay in place. As the latter is the one who preserves the iron tracks so that they do not shift from their place. The stones also have jagged edges that prevent the wooden edges from sliding over each other.
The wooden boards can bear the weight of the train and thus pass it to the small stones that distribute it on the base. This makes it easier for the tracks to face all weather conditions such as heat or rain, and it also prevents weeds from growing on the tracks.
