Looking back through the Ceneri base tunnel.

On 31 August 2020, right on schedule, the Ceneri base tunnel was handed over to Swiss Federal Railways. From the time that cablex and ARGE CPC started the project in 2012, we had many opportunities to get behind-the-scenes glimpses into work on the tunnel and to report about the exciting developments.

In our film Best of Ceneri we look back at these unforgettable milestones. What was the experience like for the people working on this project? We had the pleasure of reconnecting with three cablex builders to talk about their personal experiences with the monumental Ceneri Base Tunnel project.
