After 9 years’ construction, Germany’s third longest rail tunnel, the 9,385 m long Katzenberg Tunnel, on the new and upgraded Karlsruhe-Basle route, was opened when the timetable changed at the end of 2012, cutting down on travelling times between Freiberg-Basle. In this book, numerous engineers from the DB and the contractors involved in the project report on the engineering challenges posed by building the tunnel as well as innovative solutions and the great team effort by all those taking part.

After describing the importance of the RhineValley railway as well as the previous history and planning of the Katzenberg Tunnel, the focus is then turned on executing the construction of the 2 tunnel bores backed up by lucid presentations and further sources such as

The drive with zeri TBM, process controlling and shield drive below a creeping slope,

Furnishing the interior (innovative solid slab track and modern speed and safety systems, portal structures to master the micro pressure waves/tunnel boom) as well as

Project monitoring (consulting on environmental matters/evidence procurement measures, planning/control of commissioning and informing the public).⇥G.B.
