How are maglev trains better than average trains?

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 magnets
-no engine
-doesn't use fossil fuels
-much more costly
-relatively new compared to conventionals
-used to travel long distances
-transports people
Conventional:
-uses wheels and creates friction that causes sound
-uses fossil fuels
-does not cost as much
-slower
-used in more places
-used to travel long or short distances
-transports passengers and cargo
those are just a few things that makes maglevs diffferent than conventional trains.
Maglevs are powered by magnets, where as a regular train uses a motor and fuel/electricity.
