Key project for Europe and the region.
The 66-kilometre section of the Nordbahn between Vienna Süßenbrunn and Bernhardsthal is undergoing modernisation to improve comfort, safety, and connectivity to major European transport corridors. Rhomberg Sersa Rail Group has been awarded the contract for the renewal of the overhead contact line system.
The route between Vienna Süßenbrunn and Bernhardsthal is not only part of the Southern Line, but also of strategic importance for two core trans-European transport corridors - the Baltic–Adriatic and the Orient/Eastern Mediterranean corridors. In addition to enhancing comfort and safety, the 12 year programme aims to shorten journey times and increase the frequency of S-Bahn services. Nine stations and nine stops will be modernised and made barrier-free.
Most of the work is being carried out during ongoing railway operations, which presents a logistical challenge. The upgrade is divided into two sections: the southern section from Vienna Süßenbrunn to Gänserndorf and the northern section from Gänserndorf to the border near Bernhardsthal.
The contract secured by Rhomberg Sersa Rail Group to completely renew the overhead contact line system is a technical highlight of the project. It is one of ÖBB’s largest overhead line projects. Existing masts and cables are being replaced, and the entire overhead contact line system is being renewed. In addition, the system separation point at the national border will be modernised. On the main running tracks, different overhead line types will be installed depending on line requirements. Types 2.1 and 1.3 will ensure reliable power supply at speeds of up to 250 km/h. For secondary tracks, types 1.2 and 1.1 will be used.
Construction works began in December 2024. With the comprehensive renewal of the overhead contact line system, Rhomberg Sersa Rail Group is making a vital contribution to the sustainable development of rail transport in Austria.
