¿Por qué en las vías del tren siempre ponen PIEDRAS?

Have you ever wondered why there are stones on train tracks? Although they seem like ordinary rocks, they actually play a key role in the stability and safety of the railway system. In this video, you'll discover why this happens and how something so basic is essential for trains to operate correctly. Here, I'll explain how ballast (the stones on the tracks) works and why it's one of the most efficient engineering solutions available. You'll understand how they distribute weight, absorb vibrations, allow water drainage, and prevent the tracks from deforming under the weight of hundreds of tons of trains. All explained clearly and in an easy-to-understand way. This is one of those examples where engineering is hidden in everyday things we see all the time. From high-speed trains to traditional railway systems, you'll discover why this phenomenon occurs and how these stones make safe transportation possible worldwide. It's one of those fascinating facts that completely changes your perspective on something so commonplace.
