Provided is a hypertube transport system. Specifically, provided are a magnetically-levitated train and an infrastructure-system in which same travels, comprising: refrigerant for cooling compressed air of a hypertube train, and a compressed air cooling system utilizing the refrigerant; an apparatus and method for controlling trains operating in a vacuum tube; superconducting switches for superconducting magnets for magnetic levitation; a driving stability apparatus for the hypertube transport system; a control apparatus for trains of the hypertube transport system; and an energy harvester.

Hypertube transport system

A tube infrastructure includes a first tube; a second tube that is coupled to the first tube; and a fluid tank that is disposed to surround a coupling region of the first tube and the second tube and is filled with a fluid to seal the coupling region, wherein the fluid tank allows negative pressure to be maintained inside the first tube and the second tube.
