Maglev trains are trains which are suspended, guided and propelled (moved forward) by magnetic forces. The track of the maglev train is called the guide-way. Working of the maglev trains can be studied under the following. 1  Levitation. 2  Propulsion. 3  Guidance.
Compared to conventional (normal) trains, differences in construction affect the economics of maglev trains, making them much more efficient. For high-speed trains with wheels, wear and tear from friction along with the hammer effect from wheels on rails accelerates equipment wear and prevents high speeds.
