Ground-effect train

Type of train

A ground-effect train is a conceptualized alternative to a magnetic levitation (maglev) train. In both cases the objective is to prevent the vehicle from making contact with the ground. Whereas a maglev train accomplishes this through the use of magnetism, a ground-effect train uses an air cushion; either in the manner of a hovercraft (as in hovertrains) or using the wing-in-ground-effect design.

01Details

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 drastically affected by wind, air turbulence, and weather. Whereas the magnetic levitation train can be built 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.

Development work has been undertaken in several countries since the middle 20th century. No ground-effect train has entered regular commercial service.

Yusuke Sugahara and his team of researchers at Tohoku University, in Sendai, Japan have developed the Aero-Train that uses wings attached to a fuselage to fly inches off the ground. Dubbed a ground-effect vehicle the train is designed to be completely powered by wind and solar energy , making this a true zero-carbon transportation system.

Aérotrain

The Aérotrain was an experimental Tracked Air Cushion Vehicle (TACV), or hovertrain, developed in France from 1965 to 1977 under the engineering leadership of Jean Bertin (1917-1975), and intended to bring the French rail network to the cutting edge of land-based public transport. Though similar to a maglev design, which levitates a train car over a complex electromagnetic track to eliminate all resistance other than aerodynamic drag, the Aérotrain, also a "train without wheels", rode on an air cushion over a simple reinforced concrete track or guideway and could travel at the speed of a maglev train, without the further technical complexity and expense of its track.

Gravity train

A gravity train is a theoretical means of transportation for purposes of commuting between two points on the surface of a sphere, by following a straight tunnel connecting the two points through the interior of the sphere. In a large body such as a planet, this train could be left to accelerate using just the force of gravity, since during the first half of the trip, the downward pull towards the center of gravity would pull it towards the destination.

Ground-effect vehicle

A ground-effect vehicle, ekranoplan (from Russian: экранопла́н "screenglider"), wing-in-ground-effect (WIGE or WIG), ground-effect craft/machine (GEM), wingship, flarecraft, or surface effect vehicle, is a hybrid surface vehicle/aircraft that makes use of wings to generate minimal lift and ground effect, to reduce aerodynamic drag. Ground effect is the interaction between a moving wing and a stationary surface below it.
