projects of note are the LEVX in Washington State and the Massachusetts-based Magplane. San Diego, California USA General Atomics has a test facility in San Diego, that is used to test Union Pacific's freight shuttle in Los Angeles. The technology is "passive" (or "permanent"), using permanent magnets in a Halbach array for lift and requiring no electromagnets for either levitation or propulsion. General Atomics received US$90 million in research funding from the federal government. They are also considering their technology for high-speed passenger services. SCMaglev, Yamanashi Japan Japan has a demonstration line in Yamanashi prefecture where test train SCMaglev L0 Series Shinkansen reached , faster than any wheeled trains. The demonstration line will become part of the Chūō Shinkansen linking Tokyo and Nagoya which, is currently under construction. These trains use superconducting magnets, which allow for a larger gap, and repulsive/attractive-type electrodynamic suspension (EDS). In comparison, Transrapid uses conventional electromagnets and attractive-type electromagnetic suspension (EMS). On 15 November 2014, The Central Japan Railway Company ran eight days of testing for the experimental maglev Shinkansen train on its test track in Yamanashi Prefecture. One hundred passengers covered a route between the cities of Uenohara and Fuefuki, reaching speeds of up to . Sengenthal, Germany and Chengdu, China Transport System Bögl, a division of German construction company Max Bögl, has built a test track in Sengenthal, Bavaria, Germany. In appearance, it's more like the German M-Bahn than the Transrapid system. The vehicle tested on the track is patented in the US by Max Bögl. The company is also in a joint venture with a Chinese firm. A demonstration line has been built near Chengdu, China and two vehicles were airlifted there in June, 2000. In April 2021 a vehicle on the Chinese test track hit a top speed of . Southwest Jiaotong University, China On 31 December 2000, the first crewed high-temperature superconducting maglev was tested successfully at Southwest Jiaotong University, Chengdu, China. This system is based on the principle that bulk high-temperature superconductors can be levitated stably above or below a permanent magnet. The load was over and the levitation gap over . The system uses liquid nitrogen to cool the superconductor. Jiading Campus of Tongji University, China A maglev test track has been operating since 2006 at the Jiading Campus of Tongji University, northwest of Shanghai. The track uses the same design as the operating Shanghai Maglev. Top speed is
