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.
Night works on the 100-year-old Regensburg bridge involved the use of a tracked crane to remove the old bridge in three sections and, ultimately, replace it with a new and longer structure.

The addition of two new platforms meant a new bridge was needed. The old bridge was too short to cross what is now an 18m array of platforms.

In order to complete the construction scheme as quickly as possible, the PORR team continued work at nights and on weekends.
