Why Are There Stones Along Railway Tracks?

Why Are There Stones Along Railway Tracks? Have you ever noticed the millions of stones placed along railway tracks? 🚆 They are everywhere — under train tracks in almost every country in the world. But have you ever wondered why railways are built on top of loose rocks instead of solid concrete or dirt? In this video, we uncover the hidden engineering secret behind railway stones, also known as track ballast. You’ll discover: • Why railway tracks sit on millions of crushed stones • How these rocks support the enormous weight of trains • Why smooth stones would actually make trains dangerous • How the stones help prevent flooding and track damage • The surprising history behind the word ballast • Why even modern high-speed railways still use this system These simple looking rocks are actually part of a brilliant engineering design that has kept trains running safely for over 200 years. Next time you see a train passing by, take a look at the ground beneath the tracks — because those rocks are doing far more work than you might think.
