For each country a very important factor for the economy is the traffic. In Republic of Croatia, freight transport is mainly performed in the road traffic. Constant investment in development of roads,has led to big differences in the development of other traffic brunches and unbalanced-sharing transport cargo by branches. The European Union pleads for the development of all transport branches, and is taking all possible measures in order to change. Croatian railway projects seek to improve bussines and raise the quality level to the European standard. Port of Rijeka plans to build new berths for container ships and construction of the terminal for the transshipment of containers on rail waggons and road vehicles. To became competitive rail transport need to increase the speed, and reduce the cost of transport services. Automatization of railways and the introduction of modern transportation means increased speed, and reduce the duration of transport. By opening space for operators, the rail system will become more competitive in relation to other branches. With the opening of new operators into the rail network,on the open market encourages healthy competition among existing operators and new competitors. Therefore, rail transport will implement in the conditions of a liberalized railway market.
