It is a Magnetic Levatation train.
It goes faster than that of a regular train.
well maglevs are totally different from conventional. here are a few things that make them different: Magnetic Levitation Train:-faster-makes less sound-floats on the track-uses superconducting...
Maglevs are powered by magnets, where as a regular train uses a motor and fuel/electricity.
the initial cost of building it would be too high for other less economically advantaged countries.
