The New Rail Link through the Alps (NRLA) serving Europe
The NRLA is the biggest construction project that Switzerland has ever undertaken in its history. It comprises the Lötschberg Base Tunnel (34.6 km), the Gotthard Base Tunnel (57.1 km – the longest railway tunnel in the world) and the Ceneri Base Tunnel (15.4 km). With the opening of the Ceneri tunnel in 2020, Switzerland completed the final key element of the rail freight corridor stretching from Rotterdam to Genoa.
