PURPOSE: A micro green electric railway system is provided to reduce the size of an electric railway vehicle without using a separate power part by using the magnetic force of a superconductive magnet. CONSTITUTION: A superconductive coil is installed in a tunnel(30). A tunnel outer cover(30a) is filled with liquid nitrogen or the liquid helium. A temperature/pressure maintaining device maintains the temperature and the pressure of the tunnel outer cover. A plurality of superconductive magnets are installed in a vehicle. A vehicle supporting wheel(70a) supplies power to the vehicle. A power source(40) supplies AC power to the vehicle supporting wheel. A power converter(50) changes AC power to DC power.
