Construction has officially begun on Deutsche Bahn\u2019s Pfaffensteig Tunnel in Germany, marking a major step in the expansion of the G\u00e4ubahn railway line. The start of work was celebrated with an excavator making the ceremonial first cut.<\/p>\n

The approximately 11km-long tunnel will connect the long-distance railway station at Stuttgart Airport with the existing G\u00e4ubahn line, improving the railway connection to the Stuttgart region.<\/p>\n

TBMs to excavate 9.8km of the tunnel<\/strong><\/h5>\n

The project is divided into two project approval sections. The first covers the construction of the main tunnel, with approximately 9.8km to be excavated using two tunnel boring machines (TBMs).<\/p>\n

The connection beneath the A8 motorway and the new railway line, including the link to the underground long-distance railway station at Stuttgart Airport, will be constructed using conventional methods.<\/p>\n

The second section includes approximately 240m of tunnel to be built using the cut-and-cover method.<\/p>\n

Airport railway connection takes shape<\/strong><\/h5>\n

Preparatory work has already been completed at Stuttgart Airport\u2019s long-distance railway station. The connecting structure for the Pfaffensteig Tunnel has been constructed, and the switch connection and initial metres of track are also in place.<\/p>\n

These works form part of the wider railway infrastructure required to integrate the new tunnel with the existing network.<\/p>\n

Rail partnership delivers the project<\/strong><\/h5>\n

Deutsche Bahn is delivering the Pfaffensteig Tunnel through a rail partnership with Allianz G\u00e4ubahnausbau Nord. The consortium comprises STRABAG, Z\u00fcblin, Wayss & Freytag, Rhomberg Bahntechnik, FCP (Fritsch, Chiari & Partner ZT GmbH), Geoconsult, H\u00f6rmann, iC Consulenten, Spitzke and Swietelsky.<\/p>\n

The tunnel forms part of the broader expansion of the G\u00e4ubahn line, strengthening rail connectivity around Stuttgart and linking the airport\u2019s long-distance station with the existing railway corridor.<\/p>\n","protected":false},"excerpt":{"rendered":"
