Switzerland opened its Ceneri tunnel, completing a mammoth project cutting a new route through the Alps that should transform rail links between northern and southern Europe. Ceneri Base Tunnel

After opening the Lotschberg Base Tunnel in 2007 and the Gotthard Base Tunnel in 2016, the Ceneri in Switzerland’s southern Ticino region is the final stage of the New Railway Link through the Alps project.

The route should ease the flow of goods along a railway freight corridor running from the North Sea at Rotterdam, Europe’s largest seaport, to Genoa, Italy’s biggest port, on the Mediterranean.

It is hoped the link will slash the number of trucks rumbling through the Alps by offering an alternative rail route.

But the 15.4-kilometer-long Ceneri tunnel, which fully enters service in December, will also cut travel time for passengers crossing western Europe’s greatest mountain range.

For example, travel times between Zurich and Milan, already significantly shortened by the Gotthard tunnel, will be cut by 40 minutes to just three hours.

Transporting freight in Switzerland has long required powerful locomotives to navigate the mountain passes, as well as heavy operations to load containers onto trains at the border before crossing the landlocked country.

“This is the final link that gives us a flat line straight through the Alps,” Swiss Federal Railways chief executive Vincent Ducrot told AFP at the tunnel’s media launch on Thursday.

“In the future, we will be able to have freight trains 750 meters long that can carry up to 2,100 tons of goods” per convoy, he said, highlighting the environmental benefits.

By taking the equivalent of 3,000 trucks off the roads and transporting those containers on the new rail route, it should be possible to reduce carbon dioxide emissions by 900 tons per day, he said.

Ceneri Base Tunnel: ‘Project of the century’ Ceneri Base Tunnel

The tunnel, at 329 meters above sea level, should see 170 freight and 180 passenger trains passing through per day.

Swiss President Simonetta Sommaruga officially opened the tunnel in a ceremony marked by alphorns and musicians from German-speaking parts of Switzerland and Italian-speaking Ticino, symbolizing the new link between the north and south of the mountainous country.

Sommaruga cut the ribbon at the northern end as the first freight train passed through, heading south.

“This new train line through the Alps is the project of the century for our country,” the president told AFP.

“It is the biggest investment we have ever made,”, she said, calling it “a strong sign of an intelligent transport policy.”

The NRLA plan was initially approved by a referendum in 1992. The three-tunnel project cost 24 billion Swiss francs ($26.4 billion, 22.7 billion euros) and was partly financed by license fees on heavy goods vehicles.

The Ceneri tunnel cost 3.6 billion francs — far behind the 12.2 billion invested in the Gotthard tunnel, which is the world’s longest at 57 kilometers. Ceneri Base Tunnel
