Maglev trains use magnetic levitation to suspend and propel vehicles along guideways without physical contact. This allows maglev trains to reach speeds over 300 mph. There are two main types of maglev technology: electromagnetic suspension (EMS) which uses electromagnets to attract trains to steel guideways, and electrodynamic suspension (EDS) which uses repulsive magnetic fields between trains and guideway coils. Maglev trains have advantages over conventional trains like less noise, lower maintenance needs, and higher efficiency due to lack of friction. However, EDS systems require additional support at low speeds and EMS systems require precise tracking to maintain stability.
