Conventional high-speed rail systems face a speed/performance trade-off. Because the wheels and pantograph make contact with the rails and catenary, vibration and noise are significant the faster you go and can have a major impact on ride quality, noise, etc. In addition, when conventional trains are pushed to higher speeds, this necessarily increases maintenance costs with more frequent replacement of wheels, rails, catenary and pantograph, etc. due to the higher impact loads. By contrast, the SCMAGLEV train levitates and has no rails and no catenary, which means it is extremely stable at very high speeds and eliminates the wear and tear that a conventional system would experience.
