The article noted the need to improve the technology of repair locomotive wheelsets. We propose a model describing the process of machining tread on milling machines based on thermo-mechanical approach to cutting metal. On the basis of the model is a method for analytical determination of the forces of milling, the temperature front and rear surfaces of the carbides. Presented results of the comparison of experimental data and data obtained analytically.

A kinematical system of the test bench for experimental investigations of the frequency asynchronous driving gear is consider. Description of the kinematical system and mathematical model on the assumption of back-to-back is produces. As well as example of construction of the mechanical data family on basis of experimental data taking into account of the inner loss in the system is produces. Dynamical model of the asynchronous motor and results of the modeling in matlab simulink is produces.

There is a trouble that electrical energy of trains which have a recuperative braking uses partly for DC railway, because there are not different consumers of the electrical energy in this time. The method was offered, it allows to find optimal parameters of a stationary energy storage, which locates on a traction substation. This method can be used for designing and determination efficiency of an energy storage.

In this paper, the possibility of controlled shunt reactor (CSR) to absorb excess charging capacity in long lightly loaded transmission lines of 110 kV electric networks Nordic branch of JSC "IDGC of Siberia" - "Omskenergo." The emergence of excess reactive power leads to an increase in the voltage at the nodes of the power system and the emergence of significant power loss. The application of CSR, The calculation of the required power, the place of installation, pre-feasibility study.
