INTRO

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.

HISTORYINTRO PRINCIPLE WORKING

MAGLEV TRAIN

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.

Commercial operation

HISTORYINTRO PRINCIPLE WORKING

They work on a basic principle of magnetism i.e.

“LIKE POLE REPEL EACH OTHER AND UNLIKE POLE ATTRACT EACH OTHER.”

IMPOTRANT TERMS …

HISTORYINTRO PRINCIPLE WORKING

Levitation means rise or a cause to rise

Both the track and train exert a magnetic field and the train is

levitated by the repulsive force between these magnetic fields.

HISTORYINTRO PRINCIPLE WORKING

Maglev trains float on a cushion of air, eliminating friction. This lack of friction and the trains' aerodynamic designs allow these trains to reach the speeds of more than 310 mph (500 kph)

The Maglev Track

HISTORYINTRO PRINCIPLE WORKING

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.

*INDIA

They do not have an engine. They do not use FOSSIL FUEL. Fast Quiet Easy maintenance Environmentally friendly

◦ No emissions

ADVANTAGES …

HISTORYINTRO PRINCIPLE WORKING

Safety issues◦ Loss of power supply ◦ Or syncronization could cause serious accidents

Expensive to build◦ $10-30 million per mile(1.6 km)

DISADVANTAGES …

HISTORYINTRO PRINCIPLE WORKING

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.
