The project of aero-train engineer S.S. Waldner

In the twenties and thirties, engineers and scientists around the world worked on the development of promising vehicles. The flow of goods and passengers is constantly growing, which is why there was a need to increase the payload and speed of traffic. In addition, the problem of unloading the existing railways and highways became increasingly urgent. As a result, work began in several countries on a number of promising areas.
