The famed Gotthard Base Tunnel (GBT) has started regular commercial rail service in Switzerland. The first regular train to use GBT ferried passenger from Zurich to Lugano.
The twin-bore GBT is world’s longest and deepest railway tunnel with length of 57-kilometer. It had overtaken Japan’s Seikan tunnel (53.9 kilometers) as the longest rail tunnel in world after it was opened in June 2016 for its maiden ride.
- GBT is the first flat low-level route through the Alps Mountain. It is situated 2.3 km deep under these mountains and57-kilometer long.
- It connects northern and southern Europe and also shortens travel time for many rail routes
- It was built in 17 years’ time frame starting in 1992 as a part of AlpTransit project, also known as New Railway Link through the Alps (NRLA).
- It consists of two single-track tunnels connecting Erstfeld (Uri) with Bodio (Ticino) and passing below Sedrun (Graubünden).
- The main purpose of the GBT is to increase total transport capacity across the Alps, especially for freight.
