Maglev train

  1. 1. Magnetic TravelBy BHARAT YADAV
  2. 2. The Maglev Train HistoryIn the 1960s in Britain Eric Laithwaitedeveloped a functional maglev train. Hismaglev had 1.6 km of track and was indetail tested. His research was stopped in1973 because lack of money and hisprogress was not enough. In the1970s, Germany and Japan also beganresearch and after some failures bothnations developed mature technologies int h e1990’s……………………………………... Eric Laithwaite
  3. 3. The Maglev Train• Maglev is a short for Magnetic Levitation.• The Maglev Train is one of the fastest transport media in the whole world.• The maximum speed reached for a Maglev train has been 581 kmh in Japan.• The Maglev Train uses magnets to reach a really high velocity.• It doesn’t touch the floor. It levitates because the magnets.
  4. 4. How does it work
  5. 5. It works like this
  6. 6. MagLev “Guideways” or Tracks  Track repels magnets on undercarriage of train, sending the train forward.  Train levitates between 1 and 10 cm above guideway.
  7. 7. MagLev vs. Conventional Trains MagLev Trains Conventional TrainsNo Friction = Less Routine MaintenanceMaintenance NeededNo Engine = No fuel Engine requires fossilrequired fuelsSpeeds in excess of Speeds up to 110 mph300 mph
  8. 8. Advantages of a maglev Train• The German Transrapid is about 20 times safer han airplanes• 250 times safer than conventional railroads• 700 times safer than automobile travel• Speeds up to 500 km/h.• A accident between two maglev trains is nearly impossible because the linear induction motors prevent trains running in opposite directions.
  9. 9. Limitation’s• Cost is major issue when considering maglev trains, it costing approximately $8.5 billions.• The weight of the electromagnets• A very strong magnetic field is required to levitate the heavy trains,and maintaining the field constant requires a lot of energy which is expensive.
  10. 10. The Maglev Train and Society• The Scientifics want the Maglev train to be fast and economical.• They want it to be something that anyone can use.• The big problem about this is that the pieces for the maglev are really expensive• The procedure to build it up is very expensive as well
  11. 11. The Maglev Train and Environment Less energy consumption because no rail-track friction Requires no fossil fuel which can harm the environment. Less noise pollution since the train never hits the track MagLev guideways and trains take up less space than conventional trains
