Annual Report 2025 – ÖBB-Infrastruktur AG

ÖBB-Infrastruktur Aktiengesellschaft Group Management Report | Consolidated Financial Statements 13 Western line Around a third of all trains run on the western line, which is why a number of capacity-expansion projects are interlinked here. During the reporting period, construction work continued on the extension of the western line between Linz and Wels, as well as on the west side of Linz Central Station. Preparatory work is currently underway for the upgrade of the section between Linz Verschiebebahnhof West and Linz Signalbrücke. The Wels terminal is currently being modernised, and the administration building is due to open in 2025. The environmental impact assessment decision for the four-track expansion of the western line between Köstendorf and Salzburg was issued in 2025. Southern line The biggest highlight of the year under review was the historic opening of the Koralm Railway between Graz and Klagenfurt after 27 years of construction. It comprises 130 km of new track, 50 km of tunnels, over 100 bridges and 23 modern stations. Another key feeder line – the first electrified section of the Styrian West Railway between Wettmannstätten and Wies- Eibiswald (with a connection to the new Weststeiermark station on the Koralm Railway) – also came into service in 2025. In total, 133 km of track and station tracks will be covered by an electric overhead line. Work continued on the technical tunnel equipment for the Semmering Base Tunnel. Once the Semmering Base Tunnel opens, it will be possible to travel between Vienna and Graz in under two hours. Station modernisation projects The following stations were completed during the reporting period: – Bad Gastein, Bad Hofgastein and Dorfgastein stations (Salzburg) – Garsten station (Upper Austria) – Haus station (Styria) – Fritzens-Wattens station (Tyrol) – Arnoldstein station (Carinthia) – Kittsee station (Burgenland) – Maria Anzbach station (Lower Austria) – Maishofen-Saalbach stop (Salzburg) – Seekirchen Stadt stop (Salzburg) – Rosenburg and Kamegg (Kamptalbahn) stops (Lower Austria) – Bregenz temporary substitute station (Vorarlberg) – Bludenz station squares (Vorarlberg) Tauern route The Tauern line between Salzburg and Villach is Austria's most important transalpine connection alongside the Brenner corridor. Until summer 2025, the Tauern line between Böckstein in Salzburg and Mallnitz in Carinthia was completely closed for extensive modernisation work on the Tauern Tunnel, resulting in long-distance diversions for both passenger and freight traffic. Arlberg route Due to the refurbishment of the Arlberg road tunnel, no major work has been able to be performed on the railway line over the past two years. These were made up in a single month-long block in autumn 2025. The project managers have initiated an environmental impact assessment procedure for the double-tracking of the so-called “Klosterbogen” section near Bludenz. Brenner corridor Planning and preparatory work on the northern access route to the Brenner Base Tunnel, as part of the expansion of the Brenner rail corridor, is continuing apace. Planning is continuing on the section of the project between the national border near Kufstein and Schaftenau. The Angath exploratory tunnel was completed in 2025 on the Schaftenau–Radfeld junction section. The ÖBB-Infrastruktur Group will create additional rail capacity on the Brenner Northern Access Route in 2026 along the new section between Kundl/Radfeld and Baumkirchen by expanding and commissioning the Vomp passing station, reducing block intervals and upgrading the ETCS.
