The TPG operates trams, trolleybuses and buses for the canton of Geneva and also serves some regions in neighbouring France. Local rail services are provided by the "Chemins de Fer Fédéraux (CFF)" (Swiss Federal Railways) and passenger ferries across the lake by the "Mouettes Genevoises Navigation". The TPG shares a common fare system (Unireso) with these services and some in neighbouring France so that a single ticket can be used for any public transport within its zones and times of validity.
