In accordance with the objective of completing the internal market, which will include the possibility for all licensed railway undertakings meeting the safety conditions to provide services, access rights should, for a transitional period of up to seven years, be extended to licensed railway undertakings for the international transport of goods on a defined network, called the Trans European Rail Freight Network, including access to, and supply of, services in major terminals and ports. After this transitional period, the Trans-European Rail Freight Network should cover the entire European rail network and the railway undertakings should be granted rights of access thereto for international freight transport.
