Why Do Train Tracks Have Rocks? Engineering You Never Noticed

Описание: In this video, I reveal the brilliant reason every railway in the world uses crushed stone ballast instead of concrete—and why smooth rocks would cause trains to derail.

🚂 WHAT YOU'LL LEARN:
Why trains would sink into the ground without ballast
The physics behind aggregate interlock
How jagged rocks prevent 200-ton trains from sliding off curves
The hidden drainage system beneath every track
The surprising nautical origins of the word "ballast"
Why concrete slabs don't work for most railways

The secret lies in FIVE incredible functions these rocks perform simultaneously: weight distribution, lateral stability, drainage, weed prevention, and easy maintenance.

This simple pile of stones has kept the global railway system running for 200 years—and it's more sophisticated than you ever imagined.
