Switzerland: Delivering New Signalling on the World's Longest Rail Tunnel

Case Study 3 minute read

We take immense pride in our contribution to the groundbreaking Gotthard Tunnel project, a vital link bridging European corridors from Rotterdam to Genoa. Despite the project's complexity, we successfully delivered the entire railway system, including our cutting-edge signalling system, one year ahead of schedule.

Challenge

Shifting freight from road to rail

Switzerland is committed to shifting freight from road to rail. The Gotthard Base Tunnel is tangible evidence of that commitment: stretching for 57km beneath the Alps, it is the longest rail tunnel in the world and it plays a vital role in reducing the impact of road traffic in the fragile Alpine environment. 

Solution

ETCS Level 2 Signalling

Hitachi Rail's ETCS Level 2 signalling ensures this landmark asset is used to its full potential.

Impact

Speeds of 250km/h

The new tunnel opened in December 2016, a year ahead of schedule. Trains can now operate at up to 250km/h. The system uses continuous track-to-train radio communications to link trains to the signalling system, shaving an hour off the previous best Zurich-Milan journey time.
