In the Austro-Hungarian Monarchy the role of the railway was decisive in regional development as well as in the areas of the Hungarian Kingdom, the Pannonian Croatian areas and concerning the accessibility of the Adriatic Sea. During the 19th and 20th centuries the iron horse gave the chance for the quick development of the port of Fiume. At present in terms of Croatian-Hungarian relations on the micro regional level the role of the railway is evanescent concerning regional development. Only the Koprivnica-Zagreb-Rijeka railway line transacts Hungarian heavy traffic. The aim of my study is to present and compare the characteristics of the two eras from the point of view of transport and regional policy.
