Limmat valley railroad and Affoltern tramway

The Limmattal valley ranks among those parts of the Greater Zurich Area with the greatest development potential. The Limmattalbahn is designed primarily to accommodate the projected traffic growth and thereby relieve the central urban areas. Construction work started in 2017. From 2022 onwards, the 13.5 km line will serve some 27 stations in six municipalities between Zurich-Altstetten and Spreitenbach-Killwangen. Working as part of an engineering consortium, the business unit Infrastructure Zurich, Brugg is involved in the technical design and was mandated by Limmattalbahn AG to supervise the works for packages 1 (Altstetten station to Hermetschloo) and 4 (Bachstrasse Schlieren to Urdorf / Dietikon municipal boundary).

First stage completed after intensive work phase
The last major gap in package 1b was closed during the summer holidays: an intensive construction phase saw demolition of the Farbhof turning loop in Zurich-Altstetten for the tram line 2 to allow its extension from the city boundary to Schlieren on the track of the future Limmattalbahn. The planning and supervision of the works for the various trades was so far the biggest challenge on this project. This is because the start and end deadlines were set in stone and allowed no margin for error. At the island job site, all civil engineering works, including utility mains, road construction, track installation and overhead lines, had to be tightly coordinated and completed within a sixweek window. The rigorous three-shift regime demanded strict compliance with deadlines by the entire construction team and the meticulous coordination of site logistics. Despite a number of hitches, the first stage was completed on time and as planned. The tram line 2 extension from Zurich to Schlieren has been in operation since September 2, 2019. Work on the second stage (Schlieren – Killwangen) followed on directly from the first.
