The nature of the international traffic demanded uniting of the rules by which it is being executed. This process is performed by unification aiming to create uniform rules and harmonization/adjustment of rules that were not identical but had a common goal - the opening of the European railway market. The international organizations of the railway infrastructure management play an important role in opening of the railway market and the globalization of the transport market in Europe. When defining the basic questions of the railway infrastructure distribution, European legislation established certain principles and procedures how to determine the cost of the railway infrastructure, by fully respecting the various national development and specific characteristics of national markets. National railway administration has been left in charge of determining individually for each state, the system of cost evaluation and distribution capacity, in compliance with the general principles of the legislation at the EU level. Today the system of distribution of the railway infrastructure functions in a unique space of different railway networks, with increasing role of international organizations of associated management of the railway infrastructure. A special place in the distribution of railway infrastructure capacity belongs to the so-called “tools” of Internet software.
