Abstract: A brief review of the history of the studies and existing problems of air cushion trains in high-speed railway transportation is given. A new concept of air suspension train by using train legs instead of wheels in air film suspension high-speed track transportation in our country is proposed on the basis of the results of many experiments. The article gives details of technical proposals of air suspension trains and a summing-up of the developments and manufacture of air suspension trains nowadays, including nine new developments in, such as, the argumentation of the feasibilities and practicability of such trains, theoretical explorations, organization of documents, operation experiments, and others. And, compared with TGV, magnetic suspension, airplanes, and air cushion trains, air suspension trains have no doubt the greatest priorities in commercial compentition, safety, low energy consumption and price. At last, a predicted market demand of these trains is made. With further trchnical developments, air suspension trains will become hotspots in transportation constructions in different countries and have a promising foreground in markets.
