The roughly 27 km long Semmering Base Tunnel is being built between Gloggnitz and Muerzzuschlag in three part-sections as one of the most important major European infrastructure projects. The Austrian tunnel is scheduled to be completed in 2026. The JV Hochtief Infrastructure Austria, Implenia Austria and Thyssen Schachtbau is deploying five Komatsu wheel loaders for loading at the working face and feeding the crusher in the Gloggnitz Tunnel, the eastern construction section, where they are able to prove their efficiency even under constricted conditions. The SBT 1.1 Tunnel Gloggnitz lot embraces the setting up of the two single-track bores with a total length of some 16.1 km. They are built cyclically using the NATM (New Austrian Tunnelling Method) from the Gloggnitz portal and from the Gloggnitz intermediate point of attack via six drives, connected via 16 cross-passages, a service passage and two logistics headings.
