How does the train in China float?

An air train in China is said to be the world's first suspended maglev train system that uses permanent magnets. It can operate without power, gliding through the air without ever making contact with the track above it — and there's no rail underneath it.

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.

Maglev trains require very straight and level tracks to maintain high speeds. This necessitates extensive viaducts and tunneling, making construction costly.

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.

In Musk's original concept, each capsule would float on a 0.02–0.05 in (0.5–1.3 mm) layer of air provided under pressure to air-caster skis, similar to how pucks are levitated above an air hockey table, while still allowing higher speeds than wheels can sustain.

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.

Scientists have discovered a way of levitating ultra small objects by manipulating the Casimir force, which normally causes objects to stick together due to forces predicted by quantum field theory. This is, however, only possible for micro-objects.

Cost concerns over innovative rail The primary challenge facing maglev trains has always been cost. While all large-scale transportation systems are expensive, maglev requires a dedicated infrastructure including substations and power supplies and cannot be integrated directly into an existing transportation system.

For a variety of reasons the practice is less common in the 21st century, although a community of freight-train riders still exists. Typically, hoppers will go to a rail yard where trains stop to pick up and unload freight and switch out crew.
