osed to the actual train, the train is significantly lighter, and thus saves on drive energy. The guide way also is only switched on in the section where the maglev train is located, also cutting down on energy use. Finally the fact that the train never actually touches the rails helps to reduce wear and tear on the train, so there will be less expense repairing the train. (MVP Versuchs- un planungsgesellschaft fur Magnerbahnysteme m.b.H., 1999)
             Currently there are several areas of concern surrounding the field of maglev trains. These include whether the trains will produce high levels of noise, if they will damage the environment, and how safe they are. In answer to these concerns, maglev trains produce astoundingly little amounts of pollution, environmental or otherwise, and is one of the safest modes of transport around.
             In reference to noise pollution, Carl E. Hanson (1999) has written a paper under contract of the U.S. Department of Transportation on the subject. It states that the trains travelling at high speeds can generate noise levels over 100 dBA at the typical maximum cruising speeds, but that all of this noise is produced by the aerodynamic design of the train itself. The trains themselves create very little n
