Summary
Without wheels, there is little friction, so the train can zoom quickly.
These trains can reach speeds over 400 kilometers per hour.
They need specially built tracks, which makes them costly.
Key Points
4 points1
Magnetic levitation lifts the train above the rails.
2
Lack of wheels removes rolling friction.
3
High speeds over 400 kilometers per hour are possible.
4
Dedicated guideways are expensive to construct.
