Serbia-Montenegro

COMPLETED PROJECTS

Main design for a railway upgrading project in Montenegro
Italferr was engaged to develop the detailed design for the refurbishment of the Bar-Podgorica-Vrbnica rail line on the border with Serbia. In particular, the design work included civil works (tunnels, bridges, viaducts and stations) for the Kolašin-Podgorica and Podgorica-Bar sections, the structural upgrading of the Kolašin-Podgorica line, from km 340 + 991 to km 404 + 120 and of the Podgorica-Bar line from km 404 + 120 to km 455 + 500.
The following technology projects were also completed: systems for radio communications, systems for remote control of stable traction platforms, station interconnection monitoring, station trunk monitoring, visual information sources for passengers and the replacement of the power supply for signalling and telecommunication devices at stations.
Activities were completed in June 2011.

Updating of the Belgrade-Bar railway line
Italferr was engaged to upgrade the Belgrade-Bar rail line, between the River Danube and the Adriatic Sea. This line connects the capital of Serbia to the Adriatic port of Montenegro via a mountain route which was designed in the 1950s and finally opened in 1976. The current technical features of the line are: single electrified track, average operating speed 45 km/h (speed restrictions are due to the conditions of the permanent way and to several other critical circumstances, such as the occurrence of landslides and the instability of the bridges and viaducts); length 455 km (280 km in Serbia, 165 km in Montenegro and 10 km in Bosnia-Herzegovina); minimum radius of curvature of 300 m; minimum design speed 80 km/h; maximum gradient of 25 ‰ (the highest altitude, at 1,030 m above sea level, is reached near Kolašin); 254 tunnels for a total length of 24 % of the line; 234 bridges and viaducts for a total of 15 km. The civil engineering infrastructure along the route include one of the highest bridges in the world, soaring 200 metres over the Mala Rijeka River. The Yugoslav wars led to years of neglect, lack of maintenance and an absence of improvement works, but now the Belgrade-Bar line is under joint management of the Serbian and Montenegrin railways and international funding has enabled its partial upgrading. As part of this Study, Italferr collected data on the infrastructure, operations and passenger/freight traffic in the region, carried out software infrastructure modelling and defined and simulated future operational scenarios. It also identified the main bottlenecks and defined the work to be done in the short, medium and long term, carried out a detailed study of the improvements required for the civil works and technological installations, a financial and economic analysis of the investment programme, based on traffic data, and last but not least, an action plan to optimise line management.
Activities were completed in late 2010.
