The primary condition for the competitiveness of joint cross-border regions formed as a result of territorial and economic integration is the network of well functioning economic and social relationships, the basic condition of which is the construction of infrastructure. The Szeged-Röszke-Horgoš-Subotica-Csikéria-Bácsalmás-Baja line used to operate as part of the Fuime-Constanta line from the 1910s, and it ensured accessibility for the border region as well. As a result of economic and social changes following World War II a major part of the railway line was shut down, and the reconstruction has not taken place ever since.In November 2011 the Feasibility Study concerning Szeged-Röszke-Horgos-Subotica-Csikéria-Bácsalmás-Baja railway line was completed (HUSRB/0901/112/153 project). The study determines the improvement possibilities of the East-West railway connections of Subotica to Szeged and to Baja across the HU-SRB border.The objective of the current project is to implement the next step towards construction of the cross-border railway line of the programme area.Outputs to be achieved by the project:1.Designs for approval of Szeged-Röszke-Horgos-Subotica section2.Base documentation of the future transport network that underpins the modification of the regulation plans concerning Subotica-Csikéria-Bácsalmás-Baja section3.Environmental Impact Assessment concerning Subotica-Csikéria-Bácsalmás-Baja sectionThe documentation has to be submitted to the Serbian Republic Revision Committee and the Hungarian National Transport Authority for approval at the end of the project.The strategic objectives of the project is to improve accessibility of the DKMT Euroregion from neighbouring countries and rest of Europe by creating high quality interoperable railway connection for passenger and freight in the East-West axis of the Region. Good and cost-effective transport system is a pre-condition for maintaining high economic growth and improving the European integration. Achievements: Infrastructure is the main prerequisite for building and sustaining a network of wellfunctioning economic and social relationships and increasing the competitiveness of joint cross-border regions formed as a result of territorial and economic integration. The Szeged-Röszke-Horgoš-Subotica -Csikéria-Bácsalmás-Baja railway line had operated as part of the Fiume-Constanta line since the 1910s. As a result of the economic and social changes following World War II, a huge part of this railway line was eliminated, and it has never been reconstructed. In November 2011, a Feasibility Study concerning the Szeged-Röszke-Horgos-Subotica -Csikéria-Bácsalmás-Baja railway line was completed (within the HUSRB/0901/112/153 project). The study determines the improvement possibilities of east-to-west railway connections of Subotica to Szeged and to Baja across the HU-SRB border. The objective of the current project was to implement the next step towards constructing the cross-border railway line in the programme area. The achieved outputs of the project are: designs for approval of the Szeged- Röszke-Horgoš-Subotica section; base documentation of the future transport network that underpins the modification of the regulation plans concerning the Subotica -Csikéria-Bácsalmás-Baja section; an Environmental Impact Assessment concerning the Subotica-Csikéria-Bácsalmás-Baja section. The project achieved the first stage of the overall strategic objective to improve accessibility of the border region from the neighbouring countries and the rest of Europe by creating a high-quality interoperable railway connection for passenger and freight transport in the east-west axis of the region.
