The clip below looks first at an artists impression of what
Magnetic levitation will allow us to do in the future. It
also looks at the defining characteristics that are used in
Maglev trains. The scientific principles demonstrated are the
Meissner effect, Magnetic levitation and suspension and
the flux trapping effect.

We now see how the above scientific principles
can be applied to create simple magnetic levitation
model trains.

Here both the magnetic levitation as well as
suspension techniques are shown on a model.

People have also created model magnetic levitation
systems where the power is supplied by solar energy.
This creates an almost self sufficient unit as long as
there is sunlight as shown in the video below.

Now these principles are applied at a larger scale
to create the modern magnetic levitation train.
The movie below is by a company called Transrapid
that has created some of the most popular Maglev
trains in the world today. Here the train shown is from
Transrapid's test track in Germany.

We now look at the first commerical operation of a high speed
magnetic levitation train. This train is located in Shanghai,
connecting the city to its airport. A distance of about 35 kms.
The train reaches speeds of 430km/hr and the entire trip takes
about 1o mins.

The fastest Magnetic levitation trains are now being designed
in Japan to replace the Shinkansen or the Bullet train. They
have reached 581 km/hr on test runs.

This link gives a review of what it feels like to
travel on a high speed maglev train.
This pdf document gives a comparison study
of how much it would cost to build a Maglev
train between some large cities and normal
high speed trains between the same cities.

Another viewpoint to the same arguement.
