The European Union adopted a Directives destined to convert the rail sector in a way of competitive transport, giving place to the separation of activities of administration of the infrastructure of the own activities of the exploitation. The opening of the rail transport in diet of free competition and the allocation to the administrator of rail infrastructures of the necessary functions for the provision of services regarding transport of passengers as of commodities. This remained reflected in a series of charges, in which each country created some specific rules of fixation of charges and that has given place to prices very diverse, not only economically but also to the hour to define the same, resulted of the nonexistence of a guideline detailed of how would have to fix the same. This opening, forces the rail companies to fulfill a series of legal requirements, technicians and economics to be able to operate by the European rail network. The economic requirements remained reflected in a series of charges to credit to the administrators of rail infrastructure of the countries by where circulates a rail transport. These charges are established, although the corresponding European Directive regulates them, according to the rule of the country, what gives origin to a diversity of the same.
