On some ways to address the issue determining rerouting cargo flows costs in capacity constraints conditions

The paper examines the existing and newly designed transport routes of the Eurasian space, passing through the territories of Russia, Kazakhstan and Uzbekistan. Due to new geopolitical conditions, both transport and economic ties and cargo flows throughout the Eurasian space have changed significantly. New logistics routes require updating economic standards for calculating operating costs, cost price, as well as the tariff regulation system on existing and designed transport sections. New approaches are needed to improve interstate relations and international interaction between transport organizations of neighboring states. The transport corridors of Russia, Kazakhstan and Uzbekistan are closely linked both with each other and with the transport systems of a number of foreign countries - China, Iran, India. Therefore, it is necessary, on the one hand, to strengthen cooperation between transport organizations of these countries, and on the other hand, to resolve problems related to technological and transport-logistics interaction with these states. Thus, if the railways of the former USSR countries have very similar transportation technology and development history, then other countries are unique in this regard. It is also necessary to take into account the different approaches to the issues of transport industry management, fragmentation of the transport business, as well as issues of ownership of rolling stock and transport infrastructure. The authors emphasize the relevance of a new approach to calculating railway tariffs based on sectional cost. They provide existing and proposed dependencies for these purposes.
