Moreover, in Los Angeles, the estimated cost of a proposed maglev route is $8.5 billion, nearly four times as much as the cost of a freeway. In addition to the higher cost, maglev trains have another major disadvantage. Because they are not compatible with traditional railroad tracks, a complete infrastructure must be built for their entire route up until now.

On the other hand, magnetic levitation trains have a number of advantages. Because the train glides with no contact with rails or the ground, there are no moving parts, which means lower operational and maintenance costs, as well as far less noise. In addition, unlike conventional trains, it is more economically viable for maglev trains to travel at very high rates of speed. Furthermore, the absence of a combustion engine means no pollution, making these trains one of the more environmentally sound methods of transportation.

Over the course of their relatively short history, there has been one serious accident involving a maglev train. In September 2006, a train crashed into a service vehicle in Germany killing 23 and injuring 10. Investigators cited human error as the cause of the collision with tests.
