What is the Japanese train that floats on magnets?

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.

Technology. The Chuo Shinkansen will employ the SCMaglev technology, a maglev (magnetic levitation train) system developed by JR Central. The levitating force is generated between superconducting magnets on the trains and coils on the track.

The ATC system prevents high-speed passenger train-on-train collisions and excessive speeds. The advanced ATC system exercises complete control over the entire dedicated track and every operating train, preventing train-on-train collisions and excessive speed.

The magnetic field generated by the Superconducting Maglev has no impact on health, as it is controlled with various measures to keep it below the standards established in international guidelines (ICNIRP Guidelines). The standards are set at approx. 1/5 to 1/10 the level that could affect the human body.

Maglev train is a type of train that moves while floating in air just above its track. This way friction is minimized and the train moves very fast-at speeds exceeding 500 km per hour.

There are several disadvantages to maglev trains: - Maglev guide paths are more costly than conventional steel railway tracks. Because the magnetic coils and material used in this setup are very costly. - Maglev trains require an all-new set up right from the scratch.

The Superconducting Maglev is equipped with a braking system capable of safely stopping a train traveling at 311mph. Regenerative braking is normally used for deceleration, but if it becomes unavailable, the Superconducting maglev also has wheel disc brakes and aerodynamic brakes.

Maglev trains are “driven” by the powered guideway. Any two trains traveling the same route cannot catch up and crash into one another because they're all being powered to move at the same speed. Similarly, traditional train derailments that occur because of cornering too quickly can't happen with Maglev.

Compared to highspeed passenger rail, maglev passenger rail consumes roughly twice the power per passenger kilometer. For commercial freight I found an efficiency figure of 520 ton-miles per gallon (660 kg-km/MJ). Assuming 70kg for the average commuter passenger this gives us an efficiency of (116 kg-km/MJ) for maglev.

This reaction between the magnets creates a magnetic field. The field lifts the train off of the track. This lets air flow between the train and the guideway. The trains never touch the track; they hover just above the track.

It is considered bad manners to eat or drink inside trains, the exception being on the Shinkansen or other long-distance express trains. The smell of the food offends those around you and there is always the possibility of spilling drinks or food, so please avoid bringing food and drinks into the train.

Talking loudly on trains is considered bad mannered and ranks highly amongst the most annoying behaviors on trains in Japan. Don't talk on the phone. Only on long-distance trains on the decks between cars is talking on the phone acceptable. Set your phone to silent mode.

In Japan, the high-speed Shinkansen trains spray water onto snowy tracks to prevent the snow from blowing up into the undercarriage and re-freezing. In all areas with extreme winter conditions, de-icing, like in the airline industry, is essential.
