Railway track is the main structural and functional component of railway transport. The problems of ensuring the strength, stability and durability of railway structures are crucial for safety function of railway transport. A separate task is forecasting and modeling of safe operation times of railway transport constructions. In the world of scientific practice, various methods of solving problems to study the strength and stability of railway track constructions are used: for example, experimental and theoretical methods and mathematical modeling are applied.
Theoretical methods include standard approved methodies for engineering calculations of strength, stability and durability of railway structures give (as a rule) insufficiently precise (i.e., approximate) solutions to determine unknown deformations and stresses in structural constructions. But, in addition, theoretical methods include non-standard scientific decisions the same problems, which allow to obtain significantly more accurate results in determining these unknowns characteristics.
In this Special Issue, there is intended to collect and consider the various ways and methods of solving problems that mentioned above, and to choose the most optimal and correct methods of solutions, if it possible.
