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.

The engine for maglev trains is rather inconspicuous. Instead of using fossil fuels, the magnetic field created by the electrified coils in the guideway walls and the track combine to propel the train.
Maglev (derived from magnetic levitation) is a system of train transportation that uses two sets of electromagnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction.
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].
Both loops use magnetic repulsion to keep the train car in the optimal spot; the further it gets from the center of the guideway or the closer to the bottom, the more magnetic resistance pushes it back on track. The third set of loops is a propulsion system run by alternating current power.
In total, Maglev operation would increase net carbon dioxide emissions from 286 to 336 million kilograms per year compared to maintaining existing options, according to NASA scientist Dr. Owen Kelley. The project would also overwhelmingly harm marginalized communities.
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.
Maglevs produce little to no air pollution during operation, because no fuel is being burned, and the absence of friction makes the trains very quiet (both within and outside the cars) and provides a very smooth ride for passengers.
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.
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.
The engine for maglev trains is rather inconspicuous. Instead of using fossil fuels, the magnetic field created by the electrified coils in the guideway walls and the track combine to propel the train.
Maglev trains require very straight and level tracks to maintain high speeds. This necessitates extensive viaducts and tunneling, making construction costly.
On 22 September 2006, a Transrapid magnetic levitation (or maglev) train collided with a maintenance vehicle near Lathen, Germany, killing 23 people. It was the first fatal accident involving a maglev train.
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.
Rail emissions per passenger kilometre are currently on average around one-fifth those of air travel. Emissions from electrified passenger rail are even lower, particularly when powered by renewables or nuclear power.
Emissions comparisonRail transportation emits about 0.2 pounds of greenhouse gases per passenger mile (55 g/km) when each car is filled with 50 passengers. This figure increases to about 0.5 pounds per passenger mile (140 g/km) when only filled with half that amount.
