What's Happening to Railroad Tracks When They Lose Their STONES ?

Описание: It looks like a pile of loose, gray stones, but it is the only thing stopping a 200-ton train from sinking into the earth. If you replaced these jagged rocks with smooth river stones or a solid concrete slab, the results would be catastrophic. This is the hidden engineering of "Track Ballast."
In this first episode of The Curious Mechanism, we dig into the 200-year-old struggle between heavy steel and soft dirt. We explore why modern high-speed rail systems still rely on technology that dates back to the golden age of sailing ships.
In this video, we uncover:

The Physics of "Interlocking": Why jagged edges are stronger than concrete during a heatwave.
The "Mud Vacuum" Effect: How water can swallow a locomotive whole without proper drainage.
The Maritime Secret: How early engineers stole a safety feature from old sailing ships to save the railroads.
The Vibration Problem: Why train tracks need to "breathe" to avoid shattering like glass.

The stones you see on the tracks aren't just gravel—they are a sophisticated suspension system that keeps the global economy moving.
