The technique of an estimation of environmental contamination using the concept of total value of ecopoints or value of ecological density of pollution is considered. This makes it possible to define behaviour of atmospheric pollution from working enterprise and to estimate its ecological compatibility.

It is considered resource-saving and energy-efficient method of infrared drying of impregnated with lacquer or compound windings of traction electric motors.
The attention is given to determination of dependence of coupling force on sliding speed of wheel pairs. The analysis of different approaches in definition of coupling characteristics and their application for increase of locomotive efficiency is carried out. The description of the new total characteristic of coupling is given and on the basis of these characteristics the new ideology in the task solution of operability assurance and electric locomotive efficiency is stated.
The estimation of a level of technological processes which finds out the availability of certain interrelation between estimation of finished product quality and technological process quality is considered.
The coupler body is submitted. It is a complex spatial construction with a set of surfaces crossing in various directions. The analysis of geometry of the coupler body and real loading conditions in operation has shown that the overall estimate of stressedly-deformed state can be carried out if there is a mathematical model.
Application of active radio-frequency identification for problem solution of identification and positioning of transport means is considered. The comparison of active and passive technologies of radio-frequency identification is given; advantages of active identification are marked. Creation of system for identification of railway transport means is given.
It is shown that by development of perspective three-wire control circuit the essential shortcomings of two-wire control circuit were eliminated, including the possibility to create false control conditions from rectifier effect and entangle line wires L1 and L2. It is of great importance for safety of train operation.
The correlation detection algorithm of pulse codes with phase and amplitude modulation in conditions of interference is considered.
The detection problem of dependences between failures of devices of railway automatics and telemechanics, the choice problem of model of dependences - Bayesian networks - on the diagnostic data on the basis of application of description principle of minimum length is considered. The description of the developed algorithm and the program is submitted, examples and calculations are given.
It is shown that at train operation with layout interval there is the deterioration of some efficiency indices at reduction of layout interval. The expediency of definition of interval between consecutive trains in all cases from a condition of normative train differentiation is put under a question.

The new approach to an estimation of functional reliability of transport systems and ways of its improvement is offered. It is shown that the functional importance of an element depends on its place in structure and its role in technological process of the system. The design procedure of functional survival capability of system at failure of a concrete element on imitating model was developed. It is offered to improve functional reliability due to activization of dynamic reserves.
Some base principles of development of transport national strategy on example of air transport are offered.

The problem of series record of bridge structures at construction of the rational (optimum) decision during designing a series of bridges on a transport main line is considered. It was developed the algorithm allowing to take into account structure series at definition of numerical value of a parameter of comparison of series variants of bridge structures during its formation and a choice of optimum variant of a series of these structures.
The transformation processes of the social-valuable status of a railwayman and its structural components are considered, the further progress trend connected to reforming processes of a railway branch are determined. The role of social policy of the state and JSC Russian Railways in the formation of the social-valuable status of a railwayman was revealed.
