Ground effect train

Ground effect train

A ground effect train is an alternative to a Magnetic levitation train. In both cases the object is to prevent the vehicle from making contact with the ground. Whereas a maglev accomplishes this through the use of magnetism, a Ground effect train uses an air cushion; either in the manner of a hovercraft or using the Wing In Ground effect.

The advantages of a Ground effect train over a maglev are lower cost due to simpler construction.Disadvantages include either constant input of energy to keep the train hovering (in the case of hovercraft-like vehicles) or the necessity to keep the vehicle moving for it to remain off the ground (in the case of Wing In Ground effect vehicles). Furthermore, these vehicles may be very drastically affected by wind, air turbulence, and weather. Whereas the Magnetic levitation train is able to operate in a vacuum to minimise air resistance, the ground effect train must operate in an atmosphere in order for the air cushion to exist.
