![]() Engineering structures designed by the previously applicable for the period of construction of railway lines of normative documents to other train loads and erosion phenomena. letdown of train loads, chopping speed limit of moving traffic. ![]() Besides, continuous operation of engineer construction of railway mains, many of which are serving about 100 years, despite conducting operations has led to a significant deterioration of their physical structures and components, and eventually to a loss of the project performance parameters, i.e. In recent decades the current contents of engineering structures was aimed mainly at clearing the existing faults and warning occurrence works and further development of new faults and defects were not carried out sufficiently. It is provided with the organization and execution of work under their current maintenance and complete overhauling. Engineering structures of the transport industry in durability, reliability, stability, efficiency of service and fixed period must satisfy current modern technical requirements and provide the passage of contemporary loads with set running speed.
