According to the strategy of Russian railway transport development, by 2030 the total length of lines with speeds over 160 km/h will be almost 11 thousand km. The organisation of train traffic up to 400 km/h requires new non-traditional technical and theoretical foundations of basic solutions in the construction, provision of comfortable and safe movement of trains by infrastructure devices.

The paper considers the mathematical model of the voltage regulation system (VRS) of a permanent magnet synchronous generator describing the dynamics of motion of the main elements of the VRS when using the principle of sub-magnetisation of the generator stator backrest. The principal and structural schemes of the VRS are presented, the transfer function of the system is obtained and the stability estimation is carried out.

The factor analysis of risks in the field of train traffic safety is understood as consideration and evaluation of the level of influence of factors on the risk of occurrence of cases of violation of train traffic safety. For the purpose of automatic formation of factor analysis of risks in the automation and telemechanics economy the EC ACSUI FA of JSC "Russian Railways" is used in the part of formation of factor analysis of risks in the field of traffic safety on the infrastructure of JSC "Russian Railways".

Damages of collector traction motors of alternating current electric locomotives of the Eastern polygon of Russian Railways with different systems of ventilation are analysed. It is established that parallel ventilation of motors provides higher reliability of winding insulation and commutation than non-parallel one.

The article shows the importance of building a railway line in the Republic of Burundi. The problems and advantages of each mode of transport are described. On the basis of key indicators the analysis of existing infrastructure, cargo delivery times, distances and costs of organising multimodal transport between the main ports of East Africa is carried out.

As a result of research the necessary condition of rolling in a radial installation of a rear wheel pair of a bogie with a rigid frame is obtained. The impossibility of such rolling in all curves with radii less than 1250 m at the track arrangement according to the existing norms and taper of wheel rolling surface 1/10 is shown. The bogie movement in such curves is carried out only in chordal installation.

Simulation models of intelligent extrapolators using Chebyshev polynomials orthogonal on the set of equidistant points are considered. The relevance of the use of intelligent extrapolators in automatic control systems and predictive diagnostics is shown. The results of simulation modelling of prediction errors and recommendations on the choice of extrapolator parameters are given.

The review and analysis of the existing algorithms of distribution of passenger flows on route transport networks are carried out. The algorithm of distribution of passenger flows by time and by routes of public transport with consideration of traffic schedules and restrictions of carrying capacity is developed. The algorithm is implemented and tested in a computer programme for forecasting the distribution of passenger flows in the route system of public transport.

Provision of ecological and hygienic safety of railway transport is one of the most important tasks for preservation of the environment and human health. The article considers disinfectants with washing and deodorising action - "BIODEZHT" and "BIODEZHT Active", the use of which will provide ecological safety at operation of ecologically clean toilet complexes.
D.V. Klimova, V.V. Samoilov
The article evaluates the possibilities of using the Internet of Things to ensure the safety of railway transport workers. The use of the possibilities of the Internet of Things will give an additional tool for improving the safety system to the management of JSC "Russian Railways" on the basis of quantitative information about the working conditions of workers, their physical and psychological well-being.

Physico-chemical properties and advantages of metal-polymer pressure pipes; programme and methods of research of metal-polymer pressure pipes; results of sanitary-chemical research in model conditions are presented. The results obtained in the course of researches allow to draw a conclusion about the possibility of application of the investigated pressure metal-polymer pipes in the water supply system of passenger cars of locomotive traction.

The organisation of oil products transportation by rail includes loading, transit and shipment stages. The realisation of each of the stages is closely connected with the probability of emergencies. The solution of the issue of minimising the harmful effects of transporting dangerous goods can be achieved by developing preventive means of eliminating emergency situations associated with the spillage of petroleum products.
