Geneva Railway Station

Geneva railway station, formerly known as Geneva Cornavin railway station, is Geneva's main train station, located in the centre of the city. The immediate area surrounding it is known as Cornavin; both names can be used interchangeably.

The station has over 400 train departures every day from its eight through-platforms. Platforms 7 and 8 have French and Swiss border controls. Long distance and regional express trains leave for France without making any stops in Switzerland. Another reason to separate the tracks is the different electrical standards of the relevant railway system on either side. The French system uses 25 kV at 50 Hz AC, but the Swiss system uses 15 kV AC at 16.7 Hz.
