Tunnel infrastructure systems

Following completion of the drive, the built structure of the Ceneri Base Tunnel is now being fitted out with the mechanical, electrical and ventilation systems, without which the tunnel cannot be operated.

In order to simplify spare-parts management as well as the acceptance processes, wherever possible the same tunnel infrastructure systems will be used in the Ceneri Base Tunnel as in the Gotthard Base Tunnel. This particularly relates to the doors, the ventilation systems and the technical floors in the cross-passages. It is also the case for the special doors of the technical niches and, as already in the Gotthard Base Tunnel, the cable-protection tubes for the high-voltage line of the tractive power supply will be built into the benches.
