The project area "Baulos Kremser Tunnel BL 30" is part of the project GKB002 Lieboch (e) – Köflach (e); GKB; Section 2 Track Enhancement. Due to the electrification of the section, the required space above the clearance profile for the pantograph and the catenary support structure will be achieved by widening the cross-section. The project area "Baulos Laßnitztunnel BL 2.30" is part of the project BAT007 Border near Jennersdorf – Graz Ostbf; Electrification, Construction. The space required for the aforementioned electrification is not available in the existing tunnel profile, which is why the tunnel will be widened. The aforementioned lots require associated design services, which will be tendered in the aforementioned procedures.
