Beograd–Bar Railway Reconstruction Project, Golubovci–Bar Section

Home → Golubovci–Bar Reconstruction Project

“About the project

“The reconstruction of the specified section of the railway line is planned under the Modernization of Railway Route 4, Golubovci–Bar (Main Project), on the East Mediterranean Corridor, and is financed by the European Union through the Western Balkans Investment Framework, Infrastructure Project Facility, Technical Assistance 9 (IPF9), with reference number WB21-MNE-TRA-01, under contract number TA2018149 R0 IPA.

“The project is part of (i) the planned extension of the Core Trans-European Transport Network (TEN-T) corridor between neighboring countries (Montenegro – Serbia) to better connect the Port of Bar with TEN-T corridors VII and X, and (ii) SEETO Main Network Route 4 [Vršac (SRB – border with Romania) – Belgrade (SRB) – Bar (MNE)].

Project requirements

  • The designed line speed is 80 to 120 km/h (with restrictions in urbanized areas due to urban planning considerations).
  • “Maximum permissible axle load of rolling stock: 25 t/axle (load model E5)
  • GC through track
  • The designed track formation width must be 7.0 m;
  • The effective length of the required number of tracks at stations designed for interoperable freight trains must correspond to a track length of 750 m;
  • The effective length of the required number of platforms at stations designed for interoperable passenger trains must be 400 m;
  • “The infrastructure subsystem for traffic control, signaling, and safety must be equipped in accordance with ERTMS requirements and technical specifications;
  • “Signaling and safety installations must be equipped with ETCS Level 1 system
  • Installation of modern traffic management systems (when conditions allow)
  • Implementation of modern traffic management systems, where conditions permit
  • The effective length of the required number of platforms at stops designed for local passenger train services must be 160 m
  • Video surveillance at stations and railway stops
  • Protect railway crossings that are not yet equipped with electronic closure devices (light and sound signals and half-barriers).
  • Parking facilities for all stations and railway stops.

Specific characteristics and challenges of the project:

Complexity in complying with technical standards due to the restricted tunnel profiles (Sozina Tunnel).

Environmental permits: Works in the Skadar Lake National Park area require careful planning and approval.

ERTMS Implementation: Necessary adjustments to the legal framework and technical infrastructure.

Tunnels and bridges: Construction work is limited to a daily period of 5–6 hours to avoid disruption of regular traffic. Ensuring traffic safety during construction activities.

Level crossing modernization: Adapting technical solutions to the specific locations of level crossings. Coordinating with local communities and institutions.
