Monorail

"earth"

- I want a faster way to travel! Make it so.

The Ba Sing Se Monorail is an enormous train network stretching across the whole of Ba Sing Se, connecting all three rings. It serves as its mass transit system. The monorail is pushed from one end of the rail network to the other by a group of elite Earthbenders.

History
The monorail was the brainchild of Earth King Yi Ming, an ingenious, but impatient ruler who was tired of having to spend two full days traveling from one end of his city to the other. He tasked his engineers with finding a solution to his traveling woes.

The result was the best (and perhaps only) mass-transit system in the entire world, with no equal in speed, safety or comfort.
