At Thun railway station, many of the overhead contact line portal structures had reached the end of their service life – some dating back as far as 1922. A breakdown would have resulted in the closure of all main tracks and disrupted access to the Lötschberg Base Tunnel.
To mitigate these risks, we replaced a total of 70 masts and 30 gantries on behalf of SBB. The existing 15-kilometre catenary system remained in place but was fully readjusted by our team. At the same time, the line concept was adapted, interior switch posts were dismantled, and the affected sectioning points were upgraded with motorised or manually operated switches. Temporary switchable section insulators were also installed during the construction phase.
We thank SBB for the assignment and the trust placed in us.
