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
BENEFITS

• Maintenance • Speed• Noise
2. Energy
• Electric• Green• More Efficient
LIABILITIES
1. Original Cost
• Initial Setup
• Estimate $8.5 Billion for US
2. Weight
• strong magnetic field
• Large amount of energy and money
• Health risks
