A magnetic levitation railway is described which comprises a guideway, at least one magnetic levitation vehicle and a device for contactless, inductive transmission of electrical energy from said guideway to said vehicle. According to the invention the device comprises at least two receiver coils (27a, 27b) being formed by conductor windings and mounted on the vehicle and at least one primary conductor extending in the longitudinal direction of the guideway and being connected to a high-frequency alternating voltage source. The two receiver coils (27a, 27b) are assigned either jointly to the same primary conductor or individually to one of two primary conductors each (FIG. 4).
