Daejeon Metro
While a magnetic levitation train is capable of performing at extremely high velocities, the configurations so far consume more energy than the trains that are being used currently. This setback is one of the barriers that is preventing magnetic levitation trains from being commercialized past the experimental and entry phase. A group of scientists in the Daejeon Metropolitan Express Transit Corporation of South Korea (the corporation that operates the Daejeon Metro) focused on the braking system.
