The pure laying time was 39 months. 290 km of track have been laid. The entire 57 km of the world’s longest railway tunnel can now be continuously travelled by diesel locomotives.
The concreting train that was specially developed for the Gotthard Base Tunnel was used for the last time. At a formal ceremony in the tunnel, the “golden sleeper” of the ballastless track was cast. In total, the general contractor, Transtec Gotthard, has used around 131,000 m3 of concrete, transported 380,000 monolithic sleepers into the tunnel, and laid 290 km of rails. Around 125 workers were in action in shifts, 24 hours a day, seven days a week.
The ballastless track in the Gotthard Base Tunnel is an important factor for installation of the railway infrastructure systems. It makes rail-based transport possible for all subsequent work operations. With the end of track-laying, the first major area of the railway infrastructure systems is complete.
In the Ceneri Base Tunnel, excavation work is progressing rapidly: 85% of the entire tunnel system has already been cut.
