The principal features of the JNR system are electrodynamic suspension, null-flux magnetic guidance, and active track linear synchronous motor propulsion with on-board superconducting coil. The 7 km Miyazaki test track began as an inverted T-shape guideway, where the ML500 maglev vehicle reached 517 km/h on December 21, 1979. After that, the guideway was converted into a U-shape which was considered more favourable for vehicle design. The new system has a superconducting coil with a high magnetomotive force. This coil performs three functions of suspension, guidance, and propulsion. The guideway was reconstructed by removing the central upright and attaching side walls. The ground coils for propulsion and guidance were transferred from the central upright to the walls, while the ground coils for suspension were left in situ. The MLU001 three-car train, 28.8 m in length with a mass of about 30 t, was constructed to investigate the running characteristics of vehicles in coupled operation.
