We consider the efficiency of the passenger complex in terms of application of the modern approach to the management of the second-class carriage park. The new approach is to manage passenger cars as resource objects and "profit centers" of the passenger complex, with information about their deployment, planned inclusion into trains, depot maintenance dislocation taking into account.

The results of the construction of a specified mathematical model of a car rolling over a hump profile under the influence of a headwind are highlighted. Final analytical formulae for determining a rolling car speed and the distance traveled on the first section of the profile were received. Graphic dependence of speed and distance traveled versus time are performed.

The elements of the procurement system of materials, parts and components for domestic car repair production. An improved method for determining a procurement quality index on the example of axle bearing suppliers for Tambov wagon factory is suggested. A graphical analysis of component suppliers is represented.

The basic models of damageability and continuous propagation of cracks are presented. With the factors affecting fatigue processes in transport structures, advantages and disadvantages of the approaches are described. The necessity and proportionality of sharing models per transport damageability in CAE is substantiated.

Work of electric rolling stock in voltage dips in a traction network due to short circuits, as well as high-speed reclosing operations at traction network emergency are considered.
N.P. Grigoriev, A.V. Voprikov, A.P. Parfianovich
The pressing problem of winding life service maximization in power transformers of 25kV AC traction substations is considered. Method of determining a winding isolation wear when connecting transformers to the traction network under new schemes is given. For new transformer connection schemes to the traction network, the effect of traction network power patterns for wear winding isolation is analyzed
