Maglev is a train system that uses electromagnets to lift and propel vehicles above the track instead of rolling on wheels, which reduces friction and allows for potentially faster travel. This technology matters because it could enable trains to operate at very high speeds with greater efficiency than traditional wheel-based rail systems.

Compared to conventional railways, maglev trains have higher top speeds, superior acceleration and deceleration, lower maintenance costs, improved gradient handling, and lower noise. However, they are more expensive to build, cannot use existing infrastructure, and use more energy at high speeds.
