Genève is Geneva's main railway 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 230 train arrivals and departures every day, 4 ticket counters and 6 ticket machines. The number of ticket counters and ticket machines has changed after renovations in 2011, as well as a customs office for international trains to France and beyond. There are only 8 platforms, which makes it relatively small compared, for example, to Zurich railway station's 26 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.
