By improving its public transport networks, the Serbian authorities aim to encourage sustainable urban development. The city of Belgrade has therefore launched an ambitious project to build three driverless metro lines. Our Urban, Tunnel and Geology specialists from Tractebel in France will support clients on the biggest infrastructure project in Serbia.
Tractebel to optimize pre-feasibility design of Belgrade Metro line 1, phase 1
Our infrastructure experts will contribute to the development of the functional pre-feasibility design for the metro facilities, consisting of stations, tunnel sections and shafts. As principal consultant, we will ensure compliance with the requirements of the system contractor, and perform the review of the documentation. The scope of this mandate, our second for the Belgrade Metro project, includes delivering the following key services for each metro station facility: Review of the existing preliminary design; and preparation of the general functional design.

Serbia’s first metro takes shape
This historic urban transport project is the first metro project in the Western Balkans and the largest infrastructure project in Serbia. The project consists of three metro lines serving the Republic of Serbia’s capital. Planned in conjunction with urban developments and heavy rail transport projects, the largely underground driverless metro project will cross the city and the Sava and Danube rivers. The first two lines will converge at Savski Trg, Belgrade’s historic main railway station.
- The first line, running from north to south, will provide services to the Waterfront, the historical centre and to many urban development zones.
- The second line, running east to west and passing beneath the Sava river, will link the historical centres of Belgrade and Zemun, passing by Novi Beograd.
With the addition of a third line, already foreseen, the metro network will cover nearly 60 km and serve 61 stations.
