WHY ARE RAILWAY TRACKS ALWAYS LAID ON GRAVEL?
Ever noticed the rough gravel under railway tracks and wondered why it’s there? Well, it’s not just for looks! The gravel, called ballast, plays a crucial role in keeping the tracks stable. It evenly spreads the heavy weight of trains, preventing the tracks from sinking into the ground. It also helps with drainage, allowing rainwater to pass through so that the tracks don’t get damaged. Plus, it absorbs vibrations from moving trains, making rides smoother and reducing noise. Without gravel, tracks would shift, wear out faster, and become unsafe. So, next time you see a train zooming by, you’ll know the secret beneath its tracks!
