Well, most of us must have heard about Maglev trains, it is nothing but an abbreviation of Magnetic Levitation. Maglev trains are one of the fastest, less noisy and smoothest trains currently being plied on. Few of the countries have already started investing in this type of trains, but the only disadvantage at their end is that they need to build up a complete infrastructure for this type of trains, as unlike the normal trains it is not run on wheels. Maglev Trains started off in England and is now in use in the Eastern part of the world namely countries like China and Japan. A Maglev train can touch up a speed of more than 500 kmph and give an average of 250 kmph, making it one of the fastest running trains apart from the bullet trains.

What is Magnetic Levitation?

Magnetic Levitation In a maglev train, the body of the train floats on a magnetic field. And this train is propelled by the help of a linear induction motor. They follow the tracks with the help of magnets. This train when, floats above the guidway with the help of the magnetic field. Since it does not have any engine, the train is propelled by the guidway with the help of changing magnetic fields. As soon as the train moves into the next section, the magnetism keeps switching and the train is then able to move.

Advantages of a Maglev trains.

· The advantages of a Maglev trains are many, as it is a floating train and it does not touch any other parts the maintenance involved in it is considerably less as compared to that of other trains. The chance of any components or parts of the trains wearing out are less an d hence ideally if you look at it theoretically there should be no repairs cost at all.

· The second advantage of a Maglev train is that, there would be no friction as the whole body of the train is floating.

· Also, since there are no wheels attached to this trains the noise coming out from the trains would be less. So in short it would be less noisy and smoother as compared to other conventional trains.

· Apart from this one big advantage that a Maglev train has is the speed; it has the potential of becoming one of the fastest trains in the world.

· As far as energy consumption is considered there is no better solution that a Maglev trains, it is being propelled by magnets and they don’t need any other form of energy.

The one major disadvantage that a Maglev train has is the cost disadvantage. Use of magnetic fields instead of normal railway track is bound to be a costly affair. Then as said earlier building up the whole infrastructure to cater to the already costly maglev trains and tracks would be difficult and these tracks can only be used by Maglev trains, unlike the normal tracks which can be used by any trains.

Currently it is being tested in countries like US, Japan and Germany but because of the cost factor not many countries are willing to try a Maglev Investment.
