Question

What are the advantages & disadvantages of magnetic levitation?

Answer 1

Advantages:

A MagLev is way faster than your usual bullet train. MagLevs can reach speeds up to 500 kilometres per hour.

Due to its lack of wheels, MagLevs are quieter than normal trains, or sometimes even traffic.

MagLevs use 30% less energy than normal trains.

In theory, a MagLev and its track would require very little maintenance; since the train never touches the track there is virtually no wear and tear.

Disadvantages:

The MagLev's track is much more expensive than railroad tracks.

Whole new sets of tracks would have to be built for the MagLev to run. Many transportation vechicles in Europe run on existing track, like the TGV trains in France.

Although MagLevs are pretty quiet, noise caused by air disturbance still occur
