A superconducting eddy-current brake for high-speed trains includes a pair of superconducting magnet units with alternate arrangement of N and S poles; and a cryogenic system. The superconducting magnet units are fixed on a bottom of a bogie of the train and an air gap is provided between the superconducting magnet units and a top surface of a rail below the bogie. The cryogenic system is provided on the bogie of the train. Each superconducting magnet unit is embedded with a superconducting container including a coil case, a thermal shield and a Dewar successively from inside to outside. The coil case is filled with liquid helium. A superconducting coil is provided in the coil case and immersed in the liquid helium. A high-vacuum environment is provided in the thermal shield. Liquid nitrogen inlet and outlet pipes are provided on an outer wall of the thermal shield.
