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).
