Maglev trains

A few countries

are using

powerfulelectromagnets

to develop high-

speed trains,called maglev

trains.

Traveling atspeeds of up to

310 mph (500kph), maglevtrains could

begin

connectingdistant cities in

a few years.



3/11


How it works.

A maglev trainfloats about

10mm abovethe guide way

on a magnetic

field.

It is propelled

by the guide

way itself ratherthan an onboard

engine by

changingmagnetic fields.



4/11


How it works cont

Once the train

is pulled into

the nextsection the

magnetism

switches sothat the train is

pulled on again.

The Electro-

magnets run the

length of theguide way.

Advantages?

Well it soundshigh-tech, afloating train,they do offercertain benefitsoverconventionalsteel rail onsteel wheelrailways.

The primary

advantage is

maintenance.



6/11


Advantages? Cont

Because thetrain floats

along there isno contactwith theground and

therefore noneed for anymoving parts.

As a result

there are no

componentsthat would

wear out.

Advantages? Cont

In theory,thismeans, trains

and trackwould need nomaintenanceat all.

Note thatthere is stillair resistance.

The second

advantage is

that becausemaglev trains

float, there is

no friction.




Advantages? Cont

A third

advantage is

less noise. Because there

are no wheels

running alongthere is no

wheel noise.

However

noise due to

airdisturbance

still occurs

while the trainis in motion.




Advantages? Cont

The finaladvantage is

speed. As a result of

the threeprevious listedit is more viablefor maglevtrains to travel

extremely fast

i.e. 500km/h or300mph.

Although thisis possiblewithconventionalrail it is noteconomicallyviable.




Advantages? Cont

Ah-ha tricked ya!There is one

more advantage. Another

advantage is thatthe guide waycan be made alot thicker inplaces.

E.g. after stationsand going uphill,

Which would meana maglev couldget up to 300kmh(186mph) in only

5km wherecurrently takes18km.




Advantages? Cont

Also greater

gradients

would beapplicable.

O.k I mean it

now this was

the last one.
