The article is devoted to the problem of efficiency assessment of the absorbing automatic coupling devices. It is proposed to use the power as the efficiency criterion of the absorbing devices of various types. The computer modeling technique of shunting impact of cars is developed. The analysis of various models of absorbing devices on the basis of power consumption criterion was carried out.
The analysis results of asynchronous auxiliary machine of the modern electric locomotives of alternating current of East polygon of JSC "Russian Railways" are provided. The most damaged nodes of asynchronous auxiliary machines are defined, and the level of their influence on faultlessness of auxiliary machines is evaluated. The failure mechanism of asynchronous auxiliary machines of the modern electric locomotives of alternating current is specified.

The results of research and content analysis of heavy metals (Cd, Ni, Pb) in air of the working area of battery sections of passenger car sheds are presented. A priori estimate of occupational disease risk is made. On the basis of the obtained data the necessity of content assessment of heavy metals in air of the working area of the battery attendant is proved. The number of advices of labour condition improvement is developed.

Topical issues of investment potential assessment of the companies-owners of the rolling stock for their long-term and sustainable development for transport service improving of freight owners are considered.
The main approaches to the government regulation of railway infrastructure services, tariff regulation methods in the Russian Federation and abroad are considered. The views of the tariff regulation problem of railway infrastructure services are generalized. The foreign practice examples of the realizable approaches to the tariff regulation are given.
The partition efficiency of outputs of diagnostic objects into groups under their monitoring on the basis of sum codes is analyzed. Look-and-feel of partition of outputs in case of their monitoring on the basis of modifications of Berger codes with the smallest total amount of undetectable errors in case of the set points of the lengths of information and control vectors are marked. It is proved that the best option is half partitioning of outputs into groups.

The article is devoted to development of new macrostructure approach of the description of yard necks of railway stations. A yard neck element here is not the separate switch, but the structural channel - the group of switches providing some movement. This approach is more effective at the description of interaction of parks and yard necks, and it will allow to improve the designing design and technology solutions.
