Maglev trains • A few countries are using powerful electromagnets to develop highspeed trains, called maglev trains. • Traveling at speeds of up to 310 mph (500 kph), maglev trains could begin connecting distant cities in a few years.

How it works. • A maglev train floats about 10 mm above the guide way on a magnetic field. • It is propelled by the guide way itself rather than an onboard engine by changing magnetic fields.

How it works con’t • Once the train • The Electrois pulled into magnets run the next length of the section the guide way. magnetism switches so that the train is pulled on again.

Advantages? • Well it sounds • The primary high-tech, a advantage is floating train, maintenance. they do offer certain benefits over conventional steel rail on steel wheel railways.

Advantages? Con’t • Because the train floats along there is no contact with the ground and therefore no need for any moving parts. • As a result there are no components that would wear out.

Advantages? Con’t • In theory, this • The second means, trains advantage is and track that because would need no maglev trains maintenance float, there is at all. no friction. • Note that there is still air resistance.

Advantages? Con’t • A third • However noise advantage is due to air less noise. disturbance still occurs • Because there while the train are no wheels is in motion. running along there is no wheel noise.

Advantages? Con’t • The final advantage is speed. • As a result of the three previous listed it is more viable for maglev trains to travel extremely fast • i. e. 500 km/h or 300 mph. • Although this is possible with conventional rail it is not economically viable.

Advantages? Con’t • Ah-ha tricked ya! • E. g. after stations There is one and going uphill, more advantage. Which would mean a maglev could get • Another advantage is that up to 300 kmh (186 mph) in only the guide way 5 km where can be made a currently takes lot thicker in 18 km. places.

Advantages? Con’t • Also greater gradients would be applicable. • O. k I mean it now this was the last one. • The end
