Imagine rushing across the Japanese countryside at astonishing speeds. The wheels of your vehicle do not even touch the ground. In fact, you are floating! This dreamlike experience is will soon be a reality thanks to Japan’s famous Maglev bullet trains, which have set the latest world record for a train.
Japan is already well known for its extensive Shinkansen train system, which has been in operation since 1964. The world’s current fastest trains, however, will take a backseat to the Maglev when commuter transportation becomes available in a few short years.

How Maglev trains work
SC Maglev, or superconducting magnetic trains, were developed by the Central Japan Railway Company and the Railway Technical Research Institute beginning in the 1970s. Maglev trains work on the principle of magnetic repulsion between the cars and the track. The word maglev is actually a combination of the words “magnetic” and “levitation.” The magnetic levitation, or floating of the train, is achieved through the use of an electrodynamic suspension system, or EDS.
The rails, or guideways, contain two sets of cross connected metal coils wound into a “figure eight” pattern to form electromagnets. On the train itself are superconducting electromagnets, called bogies. When stopped, the train rests on rubber wheels. To begin motion, the train moves forward slowly on these wheels, allowing the magnets beneath the train to interact with those of the guideway. Once the train reaches 150 kilometers per hour (93 miles per hour), the magnetic force is strong enough to lift the train 100 milimeters (4 inches) off the ground, eliminating friction to allow for increasingly high speeds.
The same magnetic forces that lift the train also move it forward and keep it centered within the guideway. This is the same technology used by Tesla’s Hyperloop, which makes the ride smooth and the train exceptionally safe.
Maglev top speed
What is the Maglev train’s top speed? In April 2015, a manned superconducting Maglev train broke two previous land speed records for rail vehicles. The train was clocked at 603 kilometers per hour, or 375 miles per hour. This is much faster than the Maglev trains already operating in Shanghai, China, and in South Korea, which run at speeds of 268 to 311 miles per hour and 68 miles per hour, respectively.
The Maglev train has also exceeded previous Shinkansen world speed records in trials at the Miyazaki Test Track. Most Shinkansen trains operate at speeds of about 500 kilometers per hour (200 to 275 miles per hour). As new technologies are developed and instituted, future trains may achieve even greater velocities.
Did you know? In sixty years of operation, the Japan’s high speed rail lines have had zero fatal accidents, making them one of the safest forms of transportation in the world. The Maglev service intends to keep up that spotless record.
The Japanese Maglev train route
In 2009, the Maglev system was approved and entered commercial construction. The linear Chuo Shinkansen line is planned to link Tokyo and Nagoya by the year 2027. The trip is expected to take only forty minutes – faster than either flying between the two cities or taking the one and a half hour trip on the current Tokaido Line, available with the Japan Rail Pass. The proposed route will include stops at stations in Shinagawa, Sagamihara, Kofu, Iida, and Nakatsugawa.
The original goal of the Maglev project was to produce a train that could cover the route from Tokyo to Osaka in less than one hour. This will be achieved when the Maglev line is extended from Nagoya to Osaka, expected to be in operation by 2045.
Eighty percent of the 286 kilometers (177 mile) Maglev bullet train track will be located underground, passing under urban sprawl and mountainous terrain. The project is expected to cost the equivalent of 55 billion dollars.
When completed, the train will include sixteen carriages capable of holding one thousand passengers. At present, the public have been invited to take part on Maglev test rides. Tourists can visit the SC Maglev Parkway in Nagoya or the Yamanashi Prefectural Maglev Exhibition Center near the town of Otsuki to learn more and view Maglev test runs.
The future of high-speed trains
The Maglev may hold the current world records, but it will have its competitors. Japanese prime minister Shinzo Abe has proposed selling the technology to the United States to build a Maglev line between New York and Washington.
At the same time, plans are underway for the Hyperloop train line from Los Angeles to San Francisco, California, USA, that may reach speeds in excess of 700 miles per hour. In the meantime, the high speed hopes of Japanese citizens and tourists alike rest squarely on the Chuo Shinkansen Maglev line.
