help Ceneri Base Tunnel FAQ
When did the Ceneri Base Tunnel open to rail traffic?
The Ceneri Base Tunnel opened to regular commercial rail service in December 2020. It is the southernmost component of the NRLA (AlpTransit) project, following the earlier opening of the Gotthard Base Tunnel in 2016.
How long is the Ceneri Base Tunnel?
The tunnel spans approximately 15.4 kilometers (about 9.6 miles) through the Alps in the Swiss canton of Ticino. It provides a flat, low-elevation rail route connecting the Bellinzona and Lugano areas, eliminating the steep grades of the older Ceneri mountain line.
What is the NRLA project and how does the Ceneri fit in?
The NRLA (Neue Eisenbahn-Alpentransversale) is a massive Swiss infrastructure program to create flat rail corridors through the Alps for both freight and passenger traffic. The Ceneri Base Tunnel is the southernmost segment, complementing the Gotthard Base Tunnel to the north and completing a continuous low-level route from northern Switzerland toward the Italian border.
What travel time savings does the Ceneri Base Tunnel provide?
The tunnel reduces travel times between Lugano and Bellinzona and improves the overall north-south rail corridor through Switzerland. Combined with the Gotthard Base Tunnel, it enables faster freight and passenger service on the key European transit route connecting the Rhine valley with northern Italy.
