Maglev Trains Sloan Hazel
Electromagnetic suspension (ems) German .This system uses electromagnets on the train body itself that are attracted to the iron guideway rails. systems works at all speeds and eliminates the need for a separate low-speed suspension system. Tolerance gap is only about 1 cm
Electrodynamic suspension (EDS) Japanese Instead of using the attractive properties of magnets, It used the repelling force of magnets. Japanese trains levitate nearly 10 cm above the guideway “lift off” after about 62 mph Wheels for this lift off and slow down speed
Benefits Reduced Friction Maintenance Speed Noise Energy Electric Green More Efficient
Liabilities Original Cost Initial Setup Estimate $8.5 Billion for US Weight strong magnetic field Large amount of energy and money Health risks
