Logistical masterpiece.

The cross-city line from Altstetten through Zurich's central railway station to Oerlikon is a railway stretch of just 10km. This line passes beneath the central railway station at the Löwenstrasse underground station.

As part of the finishing works on section 4 (Oerlikon integration, subsection 4.006), PORR was contracted by the Schweizerischen Bundesbahnen to perform comprehensive civil engineering works right next to the still-operating platforms.

Project scope

  • Site facilities
  • Salvage and plant room construction
  • Tunnel mouth construction
  • Underpass
  • New construction of Regensburg bridge
  • Supporting walls on West, Middle and Hofwiesenstrasse

The section between Oerlikon and Zurich central railway station went into operation in mid-June 2014. Intercity trains from the west of Switzerland have also been using this stretch since 2015 to travel on into the east of Switzerland.
