MAGLEV TRAINSSLOAN 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
