The corrosive attack problem of railway wheels in the operating process is discussed. The influence of nonmetallic inclusions on tendency of wheel steel to corrosion cracking and fatigue strength in corrosive environments was investigated. The consecutive order showing the degree of an adverse effect of inclusions on mechanical characteristics of wheel steel in corrosive environments is established and validated.

The problem of interaction of a structure and a traffic current underlies the problems of calculation and improvement of railway stations. For a long time the rated traffic current was presented as the average multiplied by the irregularity coefficient. Then the interaction was described by means of the queuing theory. The real traffic currents are nonrandom, they are partially controlled. The article examines the fundamental principles of the interaction of the mixed traffic current and a structure.

The features of quality management of the railway transport are considered. The example of the card of business processes of the company of the freight service operator is given. The methods of business process inspections are examined. The approach to the systematization of business process inspection results is proposed.
The questions connected with modeling of effective managerial structures of transport company, McKinsey's model and organization development factors are examined. The review of the comprehensive option of the effective organizational structure of the management system is carried out, the basic diagram of "tree" of the purposes and problems of management in transport company is denoted.
The questions of information securing in the information environment of high-speed transport are examined. The existence of covert channels is proved. The realization of methods of information leakage protection through covert channels by means of monitoring of objects and subjects on the basis of the identifying systems is proposed.
Transformation methods of discrete signals in numerical automatic control systems are considered.

The research technique of traffic characteristics in the central part of the city of Ryazan on the basis of global satellite positioning technologies is provided. The research results can be applied in case of adequacy assessment of computer models of transport systems of the cities on macro, meso and micro levels.
The review of computation researches of free frequency of a rectangular plate and results of computing experiments where it is shown that the second and third frequency of a square plate are multiple, and this proves that the respective proper subspace is two-dimensional. Two respective proper forms are given.
