Analysis of possibilities to increase the capacity of M202 Zagreb GK-Rijeka railway line on section Ogulin- Škrljevo

The Port of Rijeka is the main Croatian port within the TEN-T network. This largest Croatian port and third largest city in Croatia, the city of Rijeka, are connected with the rest of Croatia and Europe by main railway line M202 Zagreb GK-Rijeka (part of the Mediterranean corridor RH2). The line capacity is limited to approximately five million tons per year. This is because of its poor technical and technological features which are mostly a direct consequence of rolling terrain of Rijeka hinterland from Ogulin to Škrljevo. From the Port of Rijeka development plans, whose implementation is under way, the importance of this railway line for freight traffic is expected to increase significantly. A number of solutions to increase the capacity of the railway section Ogulin-Škrljevo have been proposed during the last decades. However, they have not yet developed beyond the level of studies and preliminary designs. This paper presents an overview and comparison of the technical and technological characteristics of the existing railway section and several proposed solutions to increase its capacity: complete reconstruction of single track line with the introduction of more favourable horizontal and vertical elements, construction of a new double track on the most critical track subsection, and track upgrade by construction of a second track with a partial reconstruction of the existing. The objective of this analysis is to determine the most economic development of analysed railway section, harmonized with the development of the Port of Rijeka and the Rijeka railway junction, as well as other parts of the Rijeka traffic route.
