3. MAGLEV TRAIN
A few countries are using powerful
electromagnets to develop high-speed trains,
called MAGLEV TRAINS. Maglev is short for
MAGNETIC LEVITATION, which means that these
trains will float over a guideway using the basic
principles of magnets to replace the old steel
wheel and track trains.

4. The first commercial Maglev "people-mover"
was officially opened in 1984 in Birmingham,
England.
It operated between Birmingham
International Airport and Birmingham
International railway station.
It ran at 42 km/h (26 mph) .
But the system was eventually closed in 1995
due to reliability and design problems.

5. They work on a basic principle of magnetism
i.e.
“LIKE POLE REPEL EACH OTHER AND UNLIKE POLE
ATTRACT EACH OTHER.”

1.The Propulsion coil running along the track,
called a guideway.
2.The power (A.C.) supplied to the coils is used
to create magnetic fields that pull and push
the train along the track.

20. On August 11, 2006, a maglev train on the
Transrapid Shanghai airport line caught fire.
There were no injuries, and investigators believe
that the fire was caused by an electrical
problem.
