This article focuses on the issues of determining the optimal size and speed of freight and passenger trains. In developing the current methodology, research was conducted based on previous scientific research. Currently, one of the pressing issues in railway transport is the problem of soil movement in windy areas, especially in desert areas. It is important to study the negative effects of wind on railway infrastructure and provide scientifically based solutions in this area. For this purpose, the effects of wind on the stability of rolling stock were studied.
