There are more than five types of the magnetically levitated tracked vehicles, on which research and development efforts are being made. Most popular ones among the proposed types are the electrodynamic levitation, which makes use of repulsive force of superconductive, electromagnets, and the electromagnetic levitation, which makes use of attracting force of normal-conductive electromagnets. One of the problems of EDL isthe stability problem. One of the problems of EML is the small gap length between magnets on vehicle and rails on ground. Probability of contact at the small gap will limit the highest speed limit available. The probability of contact can be determined by analyses based on the power spectral density of the rail roughness.
