3rd International Scientific and Professional Conference CORRIDOR <strong>10</strong> - a sustainable way of integrations 2. REQUIREMENTS FOR MODERNISATION OF RAILWAY LINES IN SR In the area of the Slovak republic, that has been the E.U. member since 1.5.2004, the preparation of its outdated railway network modernisation started in the beginning of 1990s (practically immediatelly after the establishment of the Slovak republic in 1993). The priority of the Slovak republic is to meet the obligations concerning the TEN-T network development and the defined E.U. priority projects. From the point of view of railway infrastructure it is the interest of the Slovak republic to modernise the tracks included in the pan-European corridors no. IV, Va and VI that are the parts of the trans- European network TEN-T as fast as possible and with the highest investment priority. Due to this reason, it is a priority to realize the so called priority projects of European importance – priority project No. 17, railway axis Paris - Strassbourg - Stuttgart - Wien - Bratislava and the priority project No. 23, railway axis Gdańsk - Warszawa - Brno/Bratislava (Zwardoń PKP/ŽSR Skalité - Čadca - Žilina - Nové Mesto nad Váhom). The aim of the modernisation of railway lines in the Slovak territory is not only to reach their required technical level, characteristic for the European railways of the 21.century but also to enable a better accessibility to the trans-European transport network and the transport networks of the neighbouring states. However, the comfort, stricter requirements for the geometric position of rails, planned reconstructions of station buildings, construction of platforms of sufficient length with a barrier-free access, employment of modern train sets, etc. and operational safety (removal of level crossings, modernisation of safety equipment) have to be enhanced as well. Moreover, it is expected that the modernisation of railway infrastructure will bring a reduction of operating costs for ŽSR (Railway of Slovak republic) safety equipment that manages the traffic does not require so many staff to operate it and the modern technology significantly decreases the maintenance costs. The proposal of railway line modernisation has to respect the technical requirements in accordance with the international agreements AGC and AGTC and after realisation of this modernisation these lines have to meet the requirements for ensuring the interoperability of the European Rail Traffic Management System in order to provide the mobility of train sets and efficient use of the single European space. The modernisation of ŽSR railway lines is realized according to [2] and includes: complex reconstruction of railway substructure and superstructure including all the bridges and culverts, incorporation of platforms on all the railway stations and stops on the modernised line sections; the platforms of the railway stations are always placed in a way that the platform edge is at the first passing rail, so the platform edge is located at the height of 550 mm above the rail surface. They are in the stations where the express trains of the length of 400 m may stop and at stops where the passenger trains of the length 250 m may stop. The construction of level access to platforms is also planned. increase of the turnout layout penetrability by installing the slim turnouts; at the turnout layouts of a modernised station there is always at least one „fast“ rail crossover located between the main rails, while the turnouts in the rail crossovers and the connected turnouts for the branch rails in the common turnout layout are designed for the same speed in the diverging branch, at least 80 km.h -1 , completely new safety equipment and communication equipment, reconstruction of power supply stations, switching stations and TV, in order to increase the safety of railway operation the rail crossings are being replaced with grade separated crossings, in the places where the noise levels do not meet the given limits, the noise walls are being built. As a result of increasing the speeds to 160 km.h -1 (200 km.h -1 ), high standards are set to the geometric position of rails (direction and height ratios, track layout) of the modernised lines. The present rail lines do not often meet these requirements and the routes are often led on new track beds and only in partial sections they follow the original track axis. The crossings with roads are solved almost exclusively by grade separated crossings (some exceptions can be found in the sections designed for speeds lower than 160 km.h -1 ). In many cases it is necessary to relocate the existing roads or watercourses. Considering the geographical conditions of Slovakia, tunnel routing and the construction of new tunnels is not unusual. The latest tunnel of ŽSR lines was built in 1966. The modernisation of corridor tracks also involves complex reconstruction of catenaries – the change of power supply system from DC (3 kV) to AC (25 kV).
