Ways to increase the length of transport communications between the regions leads to the formation of new requirements to the means of transportation and directly to the roads on which these funds are transferred. In our country, traditionally the most important are railway services that are used by large number of individuals and businesses. The performance of the railway track to a great extent depend on the roadbed and largely determined by the strength of under ballast base, the general and local stability of slopes, the stability of soft soil at the base of embankments and engineering-geological factors terrain. Consideration of these factors leads researchers to follow the path complexity of mathematical models of objects in the system soil - the mound - permanent way. Given the high cost of strengthening the base path is necessary to create techniques that allow for the effects of terrain engineering and geological factors to calculate the stability of the railway track to make an accurate assessment of his condition. Developing such a methodology and use it to obtain the specific characteristics of the road condition under dynamic loads is the focus of this work.
