Szerbia – Vasútépítés – Works contracts – Section 3 Paraćin – Trupale – Medjurovo (design and build) for Railway Line under the Belgrade – Niš Railway Modernisation Project

The Works Contract covers Section 3 of the Belgrade–Niš Modernisation Project, which is divided into four subsections, (subsection 3.2 Stalać – Đunis is already contracted). The works relate to Subsections 3.1 Paraćin–Stalać, 3.3 Đunis–Trupale and 3.4 Trupale–Medjurovo. Subsection Paraćin–Stalać is 20.8 km long, while Subsection Đunis–Trupale is 37.7 km long and Subsection Trupale – Medjurovo is 6.7 km long. A total of ten stations will be reconstructed and modernised to meet the demands of both passenger and freight traffic. The design speed is 200 km/h for Subsection 3.1 and 200 km/h for Subsection 3.3. On the Subsection Trupale–Medjurovo the works include reconstruction of the existing railway line with construction of passenger platforms and underpass at station Nis Ranzirna. Across all Subsections 3.1, 3.3 and 3.4, works include reconstruction of the existing and construction of new overhead contact line (OCL) systems, as well as electrical power installations in stations, tunnels and tunnel entrances, energy facilities, relay stations, sectioning posts (including those with neutral sections), remote control systems for electric traction installations, transformer stations supplied from OCL, and lighting of grade-separated crossings and access roads. During the execution of signalling works in stations, automatic switching of turnouts and train routes will not be possible. Due to the shutdown of station signalling systems, operations will be adapted to a temporary mode. Inter-signal interlocking devices (UMZ) will be used, installed in temporary rooms for train dispatchers, with traffic managed within station areas. Some limited works on neighbouring sections may be included in the scope of the contract.
