introduction
Introduction

A technology using powerful electromagnets to develop high speed trains.

Magnetic levitation (Maglev) means that the trains will float over a guide way using the basic principles of magnets to replace the old steel wheel and track trains.

The idea has been around since 1904, but it wasn’t until 1970 Japan and Germany began researching.

introduction1
Introduction

Currently only Japan, Germany and China have operating maglev trains.

The world speed record for conventional high speed rail is held by the Japanese experimental Maglev X01: 581km/h (361mph)

It takes one minute and a half for the train to go from zero to 500km/h.

Environmental Effects

Land Take: Constructing dual system

Maglev Trains: 12m wide

Normal Rail : 14m wide + fourlane freeway 30m wide

Risk

Safe= Clean clear rail, perfect switching and control systems. However, no technology is perfect.

financial impact
Financial Impact

Very costly

For the proposed maglev link from shanghai to Hangzhou, a total distance of 169km (105miles), the budget estimated to be US $5.0 billion.

future effects positive
Future Effects (Positive)

Direct:

They help relieve road and air-travel congestion.

High speed and capacity of the vehicle increase the mass of travel (more interaction between cities)

Decrease travel time between cities.

Cleaner environment and less pollution (highly sustainable, no burning fuels)

future effects positive1
Future Effects (Positive)

Indirect:

It creates jobs (long term)

Fuel becomes cheaper (less demand)

Unintended:

Tourist attractions; tourists choose over flying to see the scenery along the journey.

future effects negative
Future Effects (Negative)

Direct:

Noise pollution and radiation affect health of surrounding residents (long term)

Accidents (no technology is perfect)

Financial burden of the country (expensive to build)

future effects negative1
Future Effects (Negative)

Indirect:

Lose jobs as bus drivers and companies.

Unintended:

Elimination of buses and conventional trains.

timeline
Timeline

5 years:

Technologies advance and make trains travel faster, more new technologies invented and make the cost of building Maglev trains cheaper.

15 years:

Totally overcome safety concerns, travel even faster, cheaper to build, more prevalent in many countries and public usage.

conclusion
Conclusion

Inoverall, the sustainability of Maglev is very positive. Although the relative costs of constructing Maglev trains are still expensive, there are many other positive factors that overshadow this.

Maglev will contribute more to our society and our planet than it will harm us.
