The purpose of the article is an experimental study of the impact of the wheelsets of a mainline diesel locomotive on the railway track on straight sections of the track. The measurements were performed on a vibration measuring device consisting of MV25 DV type sensors and an oscillation converter for a digital signal. It is proved that the indicators of dynamic characteristics comply with regulatory requirements. As a result of the conducted research, digital data was collected from the ADC and general monitoring was carried out. Measurement and signal processing are carried out using special software of a personal computer such as a "Notebook". Vertical static load of a wheelset of a railway rolling stock unit on rails: the load of a railway rolling stock unit on rails attributed to one wheelset, taking into account the actual location of the center of gravity of the superstructure.

The rail mode of transport has become the main transit of goods in States with no direct outlets to the world ocean In connection with their health and the necessary technical support key moment in the economic development of the state. In this regard, the paper discusses the negative aspects of the interaction between wheel and rail, leading to intensive wear of the wheel flange on the example operated Kazakhstan electric and diesel locomotives. To achieve this purpose was used the software package "ANSYS". As a result, define the levels of the stress-strain state of a wheel and a rail of finite-element modeling. Developed a methodology for calculating stresses in "the system wheel-rail." Recommendations for maximum permissible thickness of the ridge is machined on the profile Dmeti wheels of the locomotive TE33A. It is also proposed to apply the conformal contact of a wheel and rail that will reduce the risk of wear. [ABSTRACT FROM AUTHOR]

The increase in heavy freight traffic in recent years is fueled by an increase in demand for coal as an alternative energy resource of oil, and also steel, in the manufacture of which large quantities of iron ore are required. However, in the former Soviet Union, the use of heavy freight trains was complicated due to insufficient quality of the railway. In this regard, the article considers the features of construction truck wagons of models 12-9941 produced by LLP "Kazakhstan car-building company" according to the project of Qiqihar railway company (PRC). The laboratory testing of rolling stock conducted in Dnipropetrovsk national University of railway transport has identified the main dynamic characteristics that meet the requirements of the international standard. The use of gondola wagons of model 12- 9941 in the organization of the heavy traffic creates tensions in the construction of the permanent way, which do not exceed the permissible limits in both straight and curve track sections.

The article presents the solution for the problem of optimal distribution of electric locomotives in repair enterprises for carrying out repairs in the frame of technical service - 8 (TS-8) and increased technical service - 8 (ITS-8). The aim of the study is to improve the efficacy of a rolling stock with a simultaneous decrease in the total expenses connected with the repair of locomotives and their transportation in repair enterprises. This is possible due to a reduction in the requirement for repairs by optimization of a resource before change of wheel bandages in electric locomotives VL80C that promotes an increase in their between-repairs run.

Nowadays, the Republic of Kazakhstan is dynamically forming up its transit policy, improving its directions and the development of new vectors. This article looks into the development of the transit and transport potential of the Republic of Kazakhstan. It presents the main conclusions on the development of a feasibility study for the construction of a logistics terminal in the seaport of Lianyungang (China) as one of the directions of building transit policy, improving its direction and the formation of new vectors. The urgency of building a logistics terminal is conditioned by the necessity for national interests and further expansion of political and economic advantages of Kazakhstan. [ABSTRACT FROM AUTHOR]
