Maglevs (Magnetically leviated trains)

• The principal of a Magnet train is that floats on
  a magnetic field and is propelled by a linear
  induction motor. A maglev train floats about 10mm
  above the guidway on a magnetic field. It is
  propelled by the guidway itself rather than an
  onboard engine by changing magnetic fields.

• Advantages?
• Maintenance
• No friction since maglev train floats
• Less noise, no wheel noise
• - Speed, could get up to 300 km/h in only 5km

• Disadvantages?
• More costly than conventional steel railways
• Lack with existing infrastructure

Countries who tested the maglev trains are the
USA, Japan and Germany. In Japan they set a speed
record of 550km/h (344mph) in early 1998. A
Japanese railroad will invest US3.1 billion to
develop high-speed magnetic trains over the next
decade
