In the article, the description of wave processes in a volume-elastic stratified medium is given using the transmitted, back and refracted wave potentials. The boundary conditions at the interface of media are considered. The wave reflection and refraction coefficients by the method of potentials were found.

In modern conditions, there is the problem of rational railway transport planning according to the criterion of obtaining the maximum profit by JSC "Russian Railways". The authors suggest the methodology of rational planning and optimal strategy selection of the freight based on the game problem-solving. The theoretical justification, the algorithm and the numerical illustration are given.

The formula derivation for calculating the transversal creep related to contact spots of railway wheels of the wheel pair is given. It is shown that in the modern literature the formula for calculating the transversal creep has no physical justification as the deformation of the contacting materials. Based on the obtained formulas, a mathematical model of wheel pair motion with the nonlinear component is developed.

The article presents the process analysis and schematic solutions for electric start systems of internal combustion engines from combined current sources containing molecular energy storage systems. The advantages of using supercapacitors in the internal combustion engine start systems are indicated.

Transport plays a basic role in the national economy. The railway and ferry transportations are an integral part of international transport corridors. They connect surface communications in a single transport network. It is the most effective type of combined transportations. The organization of ferry transportations is the extremely labour-intensive task requiring the integrated control at all stages of freight delivery.

The article examines the questions of efficiency enhancement of the Ust-Luga- Baltiysk ferry. First of all, it is the increase in the fleet load based on the competent combination of economic and organizational measures to achieve greater attractiveness of this kind of communication with the Kaliningrad region, the region of special economic status.

To ensure transport safety of the Kaliningrad region, the stable operation of the Ust-Luga - Baltiysk train ferry is necessary. The demand for ferry services largely depends on the tariff policy for rail transportation in Lithuania and Belarus, which is advisable to take into account in the tariff policy of JSC "RZD".

The traction network operation simulation algorithm has been developed by dividing the traction network into simple abstract schemes - aggregates. In this case, the calculated section of traction network along the whole length is divided into cells. This principle of the traction network simulation is a significant advantage both when writing and debugging programs and when using them in operation to solve problems.

A description of the risk assessment technique for the dangerous cargo transportation on the JSC "RZD" infrastructure is given. The author describes the current types of risks, the approach to identifying the risk sources, calculating their impact and level of risks, as well as the procedure for monitoring and predictive analysis.
V.A. Aksyonov, A.M. Zavyalov, V.E. Burak, E.A. Sorokina
The authors consider the influence problem of the chemical factor on the occupational morbidity of transport workers.
O.S. Lokteva, V.A. Kochnev, D.A. Loktev
This study develops an approach based on public-private partnership and allows to solve the problems of labour safety in transport enterprises. The authors consider the example of determining the worker fatigue signs using the proposed mathematical support for processing images obtained with a smartphone.

The article is devoted to the labour safety improving and the injury risk-reducing of contact network electricians during scheduled works on maintenance and repair of railway transport infrastructure facilities. The technique basis is developed, and the head of the department can regulate the operation conditions and performers depending on the received risk values.
V.S. Kosyakin, Z.P. Oshchepkov, A.M. Zavyalov
The authors proposed a model for the formation of processes occurring in accidents using Petri nets and theoretical foundations of the Reason's model to ensure a comprehensive analysis of the accident causes, to identify existing patterns and prerequisites for the occurrence of occupational injuries. The succession of active and latent failures contributing to the occurrence of an industrial accident has been identified.
