more than 600 km/h on a line that has accumulated years of delays

In 2015, a seven-car prototype in Japan made us dream with the tremendous speeds that the trains of the future would have, with the Japanese country as the main standard bearer. The L0 Series train reached 603 km/h on the Yamanashi test line, becoming the fastest manned railway vehicle ever recorded at the time.

More than a decade later, that record still standsalthough the promise of its commercial use has yet to materialize. And the line that is supposed to bring it to travelers accumulates years of delays.

magnetic levitation. The L0 Series works via superconducting magnetic levitation, using powerful magnets along the track and in the train that interact to lift the vehicle on the track, completely eliminating physical contact with the tracks. Without friction, without mechanical noise, without wear, and with heart-stopping speeds.

The system is known as SCMaglev and uses an electrodynamic suspension, different from that used in the Shanghai maglev. Japan National Railways began researching this type of propulsion in 1962 with a clear objective: to connect Tokyo and Osaka in one hour. They have had that dream for more than six decades.

Chūō Shinkansen. This is the maglev line under construction between Tokyo and Nagoya, with plans to extend it to Osaka. The idea is that it will be established between Shinagawa and Nagoya stations, with stops in Sagamihara, Kōfu, Iida and Nakatsugawa. The line is not intended to replace the legendary Tokaido Shinkansen, but it will exist to offer travelers a much faster alternative. The line would connect Tokyo and Nagoya in 40 minutes and, later, Tokyo and Osaka in 67 minutes, at a maximum speed of 505 km/h.

Today the fastest Nozomi (Japan’s fastest high-speed train service) takes around two and a half hours between the two cities. With Chūō Shinkansen, the idea is that approximately 90% of the 286-kilometer route to Nagoya passes through tunnels, instead of following the coast, as the Tokaido does. This decision is also the root of much of their problems.

ORa prefecture and a river. The main obstacle was that the then governor of Shizuoka, Kawakatsu Heita, denied permission to drill one of the tunnels under the Japanese Southern Alps for environmental reasons. The argument was that the impact studies had been carried out with little rigor and that the excavations could affect the bed of the Oi River. The section in question affected just 8.9 kilometers of tunnel within Shizuoka, but it was enough to block the entire project for years.

Without that section, the rest of the work could not be completed. However, the current governor of the region, Yasutomo Suzuki, authorized the geotechnical inspection prior, but the works are still in progress.

A calendar full of delays. In 2024, JR Central president Shunsuke Niwa publicly ruled out opening in 2027 and targeted 2034 as the new minimum date. But the story doesn’t end there. Last October, JR Central postponed the arrival to 2035. Construction costs have already skyrocketed by more than 50% to 11 trillion yen (about 61 billion euros), according to RailTech. The section to Osaka, for its part, It would not arrive until 2037 at best.

The threat from China. In July of last year, during the World High Speed ​​Congress held in Beijing, the state-owned CRRC presented a maglev prototype Designed to reach 600 km/h. The train runs on rubber wheels at low speed and switches to magnetic levitation when exceeding 150 km/h. The Asia Times shares that it will still take a long time to put it into commercial use, and that market demand, rather than technology, is the main obstacle.

But there is more: the T-Flight project from the state company CASIC, which combines magnetic levitation with hyperloop-style vacuum tubes, has already reached 623 km/h in tests in 2024, with the goal of exceeding 1,000 km/h soon. China has also, for years, the only commercial maglev in the world that operates regularly: the Shanghai Maglev, which circulates at 430 km/h.
