Bucharest faces increasing difficulties in providing good quality transport for its citizens. Car numbers have been increasing, resulting in significant congestion, pollution and parking problems. Although a metro network exists, there is an urgent need for substantial investments into it. In order to take a step in this direction, this project supports the preparation of a pre-feasibility study and a feasibility study required for an important extension of the M4 metro line in Bucharest, between Gara de Nord and Gara Progresu. The extension includes 14 km of underground line with 14 stations, fixed installations and rolling stock at an estimated cost of over 1 billion Euro. It links the city center to the south of Bucharest and to two major railway stations. The PFS and the FS are required to secure financing for this large infrastructure project.

With this project, the operator Metrorex, will be provided with an in-depth analysis of the optimal option for the extension of the M4 metro line in order to allow the financing and implementation of this major urban transportation project in Bucharest.


The goal of the project is to elaborate the PFS and FS of the M4 line extension from Bucharest North railway station (Gara de Nord) to Progresu railway station (Gara Progresu), comprising 14 kilometers of metro rail, including excavations and tunnels for rail network and stations respectively, 14 stations, signaling, electro-mechanical system, all ancillary facilities and rolling stock.
