Maglev is a system in which the vehicle runs levitated from the guide way (corresponding to the rail tracks of conventional railways) by using electromagnetic forces between superconducting magnets onboard the vehicle and coils on the ground [10].
Rather than using fossil fuels, these trains are propelled by varying shifts in the horizontal magnetic fields that alternately attract and repel along the rails.
Maglev train systems use powerful electromagnets to float the trains over a guideway, instead of the old steel wheel and track system. A system called electromagnetic suspension suspends, guides, and propels the trains. A large number of magnets provide controlled tension for lift and propulsion along a track.
In the Superconducting Maglev system, liquid helium is used to cool the superconducting material, niobium-titanium alloy, to 452 degrees Fahrenheit below zero.

Maglev trains require very straight and level tracks to maintain high speeds. This necessitates extensive viaducts and tunneling, making construction costly.
If guideway power is lost on the move, the Transrapid is still able to generate levitation down to 10 kilometres per hour (6.2 mph) speed, using the power from onboard batteries.
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.
Cost concerns over innovative railThe 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.
SNCF, widely regarded as one of the best high-speed rail operators in the world, has had 4 profitable years and 5 loss-generating years since 2012. The Shanghai Metro Maglev has never been profitable. Clearly, there is an issue with passenger transport. No mode of transportation can consistently generate profits.
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.
Present Maglev systems cost 30 million dollars or more per mile. Described is an advanced third generation Maglev system with technology improvements that will result in a cost of 10 million dollars per mile. Plotkin, D.; Kim, S. Lever, J.H.
There are only three countries in the world that currently have operational Maglev Trains: China, Japan, and Korea. Maglev trains are much more efficient than traditional trains and hold the speed record for trains (603km/h).
Hermann Kemper (* April 5, 1892 Nortrup, Germany, in the district of Osnabrueck, † July 13, 1977) was a German engineer and is considered by many the inventor of the basic maglev concept. In 1922, Hermann Kemper began his research about magnetic levitation.
A series of German patents for magnetic levitation trains propelled by linear motors were awarded to Hermann Kemper between 1937 and 1941. An early maglev train was described in U.S. Patent 3,158,765, Magnetic system of transportation, by G. R. Polgreen on 25 August 1959.
number one the l-0 series maglev. the crown for the fastest training commercial service goes to the l-0 series maglev in Japan the train was developed for the central Japan Railway company or the Jr Central for short and boasts the top speed. of 375 miles per hour like most of the fastest trains in the world.
