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. Attempts were made to create high-speed rail systems with propulsion aircraft of the aviation type (so-called aerial cars), monorail transport, etc. In 1933, the Soviet designers created and built a prototype of a new vehicle, in which both the monorail and aircraft engines were used simultaneously.
The author of the original idea was a self-taught engineer Sevastian Sevastyanovich Waldner. In 1915, he was drafted into the army, where he was taught to drive a car and carry out all the necessary maintenance work on equipment. S. Waldner showed great interest in various mechanisms and techniques, which eventually led to the emergence of several original projects. So, already in the second half of the tenths S. Waldner took part in the creation of promising high-speed armored rubber "Matval" and several other types of railway equipment. In the early twenties, the designer continued his research on the subject of high-speed vehicles, the result of which was the creation of a prototype of aero wagon.
