Our work on Sihltal Zürich Uetliberg Bahn’s (SZU) Manesse Tunnel got under way on 6 June 2021 with the dismantling of the existing overhead contact line. In just a short space of time across two shifts, the overhead contact line was taken apart and temporarily propped up in front of the tunnel.

Construction work began on the Manesse Tunnel on 18 July 2021. The tunnel was fitted with an overhead conductor rail and Malvie supporting structures, as the tunnel's dimensions did not allow for a catenary system. Nevertheless, we managed to meet all the specifications and keep to the very challenging tight schedule with its final deadline of 28 July 2021.

We would like to thank our entire construction team and everyone involved in the project for their tireless efforts.
