The superconducting maglev system features an electrodynamic levitation system (EDS) which enables a super high speed running without any special control device for levitating a coach as well as guiding one. Using this fundamental method, we developed and designed a new test line, which is mainly composed of vehicle, guideway, linear synchronous motor (LSM) and so on. To be a practical transport means in the 21st century for high speed operations, the maglev system requires high running stability and perfect safety, including the friendliness to the environment, even if it may involve all the possible risks which originate from external disturbances or any other troubles. To fulfill these requirements, we conducted many laboratory works and full-scale running tests. Through these efforts, we have identified the problems, devised countermeasures to solve them, and developed subsystems. The design of the Yamanashi test line is based on the achievements so far gained. Today, the development is coming into a more practical phase of assessing the reliability, the durability, and the economic efficiency using a new long test line.
