RZD International completed the construction of two largest railway facilities in the modern history of Serbia
Russian company RZD International completed more than six months ahead of schedule the construction of the longest railway viaduct in Serbia in the Danube river floodplain and the first ballastless tunnel Cortanovci. These unique engineering facilities will become part of the first in Serbia high-speed railway section Stara Pazova - Novi Sad of the Belgrade - Budapest line.

In April the objects were successfully inspected by the Ministry of Construction, Transport and Infrastructure of the Republic of Serbia for compliance with design solutions.

Before putting the facilities into operation, scheduled for the end of 2021, works on the arrangement of the catenary system, track laying, as well as pre-launch tests will be carried out in fall 2021.

The viaduct construction works began on November 1, 2017 and were completed 6 months ahead of schedule. Its length reaches 3 km, and the height of individual pillars is 26 meters, which is comparable to the height of an 8-storey building. The viaduct is located at the exit from the Cortanovci tunnel in front of the town of Sremski Karlovci in the floodplain of the Danube River. Part of the structure is on the slope, therefore, to ensure the reliability of the facility during its construction and operation, 20 landslide protection structures were constructed.

The Cortanovci tunnel consists of two parallel bores with a total length of 2.2 km. Its construction was carried out in a continuous mode since September 2017 and was completed 7 months earlier than the contract terms. The construction of the tunnel itself took 3 years. The tunneling was carried out simultaneously from four points of the two bores of northern and southern portals. Now the track is being laid in the tunnel.

During the construction advanced Russian and international technologies were used. They were tested during the construction of Olympic facilities in Sochi. Supervisory authorities, accredited laboratories and independent consultants constantly monitored the quality and progress of the work. The period of safe operation of the facilities established by the project will be at least 100 years.

RZD International continues works on the construction and modernization of the railway on the Stara Pazova - Novi Sad section of the Belgrade - Budapest line of the Trans-European Transport Corridor X. After the completion of all works on the project, passenger trains will be able to reach speed of up to 200 km/h on this section, and freight trains - up to 130 km/h.

Sergey Stolyarov, Director General of RZD International LLC: “We are proud to be the company that was entrusted with the construction of the most technically complex and large-scale facilities on the line. We are convinced that we are building not only the railway infrastructure, but also shaping a new image of Serbia - a modern country with the latest high-speed technologies, making full use of its geographical position at the “heart” of Europe. The new viaduct and tunnel will not only ensure the rapid movement of people and goods, but, thanks to their beauty and pleasing views, will become the truly sightseeing attractions of the region. "
