Two Herrenknecht shields successfully accomplished their mission in the Zurich-Thalwil core project of the Bahn 2000 (Railway 2000) project (Zimmerberg Base Tunnel). In March 1999, the mixshield TBM (Ø 12.36 m) launched from contract section 2.01. On the 2.7 km route, ca. 2,000 m was through freshwater molasse and ca. 700 m through soft mixed ground (crushed stone and deposits). The mix shield was equipped to drive through rock and soft mixed ground.
