Based on past experience, we know that Geneva-Cornavin station is a vital crossing point for three railway systems (Swiss, French and freight traffic), meaning that it has to accommodate a traffic volume of more than 800 trains per day. 

The station is currently showing signs of severe congestion. When the Léman Express (Coppet–Geneva–Annemasse) is put into operation at the end of 2019, new international, national or regional services will no longer be able to be implemented.

We therefore need to develop the Geneva railway hub so that you can benefit from these new opportunities and those of the future.

• We are building two underground tracks leading from/towards Lausanne, which will connect to a central underground platform beneath the current Cornavin station.
• This underground extension envisages the construction of a double-track, instead of single-track, tunnel between the underground station and the airport.
• These upgrades will offer more room for introducing new services and make it possible to offer even more comfort and safety for passengers. 
  
• We are coordinating this work with projects by the Canton of Geneva and City of Geneva in order to optimise mobility interchanges, revitalise urban spaces and develop the area surrounding Cornavin. 

The estimated cost is CHF 1,600 million.

Funding is provided by the Swiss Confederation, the Canton of Geneva and the City of Geneva.
