Abstract. The systematical assessment of the existing complex of juridical and normative documents, concerning the obligatory demands towards the infrastructure of the railway objects, including track, performed the existing problem of juridical collisions between those documents.
The problem of the lack of risk assessment in the regulatory and technical documents, governing the requirements for railway infrastructure and track facilities, is obvious.
The conclusion is made about the necessity of improving, systematization and elimination of contradictions in the system of legal acts in the field of establishing mandatory requirements, and requirements, applied to the infrastructure of railway transport on a voluntary basis, as well as to the design processes (including surveys), construction and operation.

Abstract. The article describes a study for determination of the optimal value of outer rail cant by life cycle cost criteria. Calculations were based on results of complex research. Research includes dynamic tests, field observations on the track conditions in more than one hundred railway curves, and life cost calculations for curves under various operating conditions with different amounts of unbalanced accelerations. Life cycle cost was calculated as the amount of costs from overhaul to the next overhaul.
During the calculations for every indicator of technical condition for track superstructure, main dependences were determined. Costs of maintenance-of-way were determined depending on the curve radius, outer rail cant and unbalanced acceleration.
Based on the results of these studies, the Russian Railways OJSC has developed and approved a guideline for determining the elevation of the outer rail and allowable speeds in curved track sections for lines of various specializations.

Abstract. For several decades, technical and economic problems of increasing axle load of freight cars have been studied in Russia and abroad. One of the main areas of research is to study the effect of increasing axle loads on the change of railway track damageability, on the change of structural life and the change in the level of expenditures on its current maintenance. The article describes the experience of assessing the impact of increasing axle loads on the level of costs for the current maintenance of the track in terms of the replacement of rails and railway sleepers and elimination of irregularities in the geometry of the rail, depending on the track design. This method has been developed for predicting changes in labor costs on specific sections of the railways of Russian Railways OJSC, taking into account the part of innovative cars in the car traffic flow. The main requirements for the maintenance and repair of the track in the areas of interchange of vehicles with high axle load are determined.
Reduction of costs for the current operation of the track depending on the classification of railway lines
Keywords: direct costs for the current operation of the track infrastructure, annual budgeting, linear, regional and Central levels of budgeting, autumn and spring Commission inspections, labor costs, material costs, maintenance costs of machines and mechanisms, program and target planning, resource consumption standards, outsourcing companies.

Abstract. The effect is based on the determination of direct costs for the current operation of the track infrastructure at the linear, regional and Central levels, taking into account the classification and specialization of railway lines within the framework of annual budgeting. The basis of efficiency is the determination of costs, taking into account the volume of the production plan of the distance of the path, formed by its production and technical Department in accordance with a comprehensive assessment of the infrastructure of the track economy, taking into account the results of the autumn Commission inspection.

Abstract. A comparative analysis of the development of cracks in the rails, laid in the last century and the present. The models for the development of cracks were built 21.1, 21.2, 53.1, 69 based on the construction of a finite element model of the rail and the possibilities of predicting the further development of cracks were evaluated.
