On April 21, 2015, a seven-car train entered a concrete guideway tunneled through the mountains of Yamanashi Prefecture and accelerated past 600 kilometers per hour. For a little over ten seconds, the L0 Series prototype floated above its track on nothing but magnetic force, traveling faster than any crewed rail vehicle in history: 603 km/h, or 375 miles per hour. There were no wheels touching the ground. There was no friction to overcome. The superconducting magnets aboard the train, cooled to near absolute zero with liquid helium, generated fields so powerful that aluminum coils in the guideway walls pushed back with equal force, lifting the entire vehicle ten centimeters into the air and propelling it forward. This was not a stunt. This was a rehearsal. Central Japan Railway Company has been building toward this moment since 1972, and the commercial line it will serve -- the Chuo Shinkansen between Tokyo and Nagoya -- is already under construction.

Japan's superconducting maglev program began in the late 1960s, shortly after Brookhaven National Laboratory patented superconducting magnetic levitation technology in the United States in 1969. Japan National Railways announced its own SCMaglev development program and made its f...

The SCMaglev uses electrodynamic suspension, a system fundamentally different from the electromagnetic suspension used by Germany's Transrapid. The train's bogies carry superconducting magnets that generate intense, stable magnetic fields. As the train moves along the guideway, t...

Since 2010, the company has pitched the SCMaglev for international markets, with the Northeast Corridor of the United States as a primary target. The proposed Northeast Maglev would connect Washington, D.C. and Baltimore as a firs...
