ELI5: Explain Like I'm 5

Cargo Sous Terrain

Cargo Sous Terrain is like a secret underground highway that helps in delivering things like packages and goods quickly and safely across cities. It is like a long tunnel that is dug underneath the ground, and special kind of trucks or wagons can travel through it to deliver things. It is like a conveyor belt that moves items around, except it is underground. The trucks and wagons move through a tunnel that is made of strong materials so that it can carry heavy weights without cracking. And because it is underground, it does not have to share space with other cars, buses or bikes that can cause traffic. This makes it faster and more efficient. Isn't that cool!
