Abstract
In a method of transmitting electromagnetic signals between a stationary transmitting/receiving station and a transmitting/receiving station in a magnetic levitation train vehicle, the magnetic levitation train vehicle is guided on a travel path that includes stator laminations arranged on its underside. Signals to be transmitted are coupled from a travel-path-side coupling-in point connected with the stationary transmitting/receiving station into the stator laminations of at least one travel path side of the magnetic levitation train, and are decoupled from a vehicle-side coupling-out point connected with the transmitting/receiving station in the vehicle out of the stator laminations and vice-versa. The stator laminations are used as a transport medium of signals between the respective coupling-in and coupling-out point.
