Gotthard Base Tunnel

The Gotthard Base Tunnel consists of two 57-kilometres-long single-track tubes. Including all cross-passages, access tunnels and shafts, the total length of the tunnel system is over 152 km. It links the north portal at Erstfeld with the south portal at Bodio. With a rock overburden of up to 2 300 metres, the Gotthard Base Tunnel is not only the world’s longest, but also the world’s deepest, railway tunnel constructed to date.

Two multifunction stations, at Faido and Sedrun, divide both tubes into three approximately equally long sections. The multifunction stations each contain emergency-stop stations and two track crossovers. In the event of an incident, such as a fire in a train or a fault in the Gotthard Base Tunnel, whenever possible the affected train travels out of the tunnel into the open air. If this is not possible, the train driver halts the train at one of the emergency-stop stations.

Besides the tunnel itself, numerous built structures, such as underpasses and bridges, are required for the tunnel approaches. In the Reuss valley in the canton of Uri, the overground section crosses inhabited areas, roads, rivers and agricultural land. Protective measures against noise, dust and floods, as well as for nature conservation, are therefore challenges that are just as important as the technical implementation of the new railway line.

The Gotthard Base Tunnel was officially inaugurated on June 1, 2016, and will be opened for scheduled commercial services in December 2016.
