RZD International (a subsidiary of Russian Railways) has finished the Cortanovci tunnel excavation works on the Stara Pazova-Novi Sad section of the Belgrade-Budapest railway line. The facility is now 91% competed.

The Cortanovci tunnel consists of two parallel single-track tunnels with a total length of 2.2 km. Today, the crews have completed tunneling in the left bore from the northern and southern entrances.

The right bore was dug through in early April. Also, more than 1.3 linear kilometers of permanent lining of the tunnel have been completed, anti-landslide protective structures have been equipped, and one of two transverse service walkways has been excavated. In total, during construction, it will be necessary to excavate more than 300,000 m3 of soil and lay more than 170,000 m3 of concrete using almost 12,000 t of reinforcement and steel metal structures.

This progress was highly lauded by Deputy Prime Minister of the Republic of Serbia and Minister of Construction, Transport, and Infrastructure Zorana Mihajlović, who visited the construction site today.

RZD International is implementing a large-scale project for the reconstruction of Serbian railways on a particularly important section of the Belgrade-Budapest line. It is here that two unique structures are being constructed. The tunnel and the viaduct in Čortanovci constitute a unified complex of railway structures that will ensure the speed of trains up to 200 km/h.

The company is also reconstructing and building on the Stara Pazova-Novi Sad high-speed double-track railway line. As part of the project, the track’s upper structure is being built and 28 artificial structures are under construction: galleries, viaducts, pedestrian overpasses, bridges, including the new Beshka station and the Karlovački Vinogradi roadside station; the Injia, Sremski Karlovci, and Petrovoradin stations are also being reconstructed.

In addition, activities are underway as part of a agreement signed in January 2019 between RZD International and JSC Serbian Railways Infrastructure that includes the comprehensive modernization and reconstruction of signaling, centralization, and blocking systems, as well as communications and telecommunications with the creation of a single dispatch center for controlling train traffic in Serbia. It will allow the country’s railways to reach a fundamentally higher technological level of management, digital planning and forecasting of freight and passenger traffic. These works will be completed in several stages between 2023 and 2025.
