The present invention relates to a tube railroad system using a magneto hydrodynamic propulsion device applying non-contact power supply technology and an operation method thereof capable of comprising a hollow tunnel and impounding the water (conductive fluid) of a predetermined water level. The present invention comprises a tube structure (100) which forms a plurality of guide tracks (110) inside; a railroad vehicle (200) which is supported on the upper part of the water of the tube structure (100), guides the railroad vehicle by enabling a plurality of guide wheels (210) to correspond to a groove formed in the guide tracks (110), and prevents the shock of the tube structure (100) to the inner side; the magneto hydrodynamic propulsion device (300) which is positioned in a lower end unit of the railroad vehicle (200) as module types, is received in the water of the tube structure (100), and controls the propulsion and the brake of the railroad vehicle (200) according to a magnetic field of the water which performs a function of a conductive fluid by applying DC voltage to a superconductive DC magnet; and a non-contact power supply system (400) which is buried in the lower part of the tube structure (100) and offers power to the magneto hydrodynamic propulsion device (300). The present invention is provided to apply the non-contact power supply technology to the magneto hydrodynamic propulsion device and the tube railroad system, thereby supplying the DC power required in an MHD propulsion system to the railroad vehicle and offering an economical system with cheap system construction costs.
