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.

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.

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.

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.
