# Semitan

Semitan is the company responsible for the comprehensive public transport network of Nantes Métropole, the urban community of the French city of Nantes. The network operated by Semitan is marketed under the name and logo TAN and this abbreviated form is also sometimes used to refer to the company. Semitan is itself an acronym for the Société d'Economie Mixte des Transports de l'Agglomération Nantaise. The TAN network comprises three Tramway lines, two Busway lines, an extensive network of buses, an airport shuttle bus line, two Navibus lines and a night bus network. A single common fare system covers all these modes and also extends to suburban trains within the Métropole boundaries, although these trains are not operated by Semitan.
Semitan is a mixed private and public sector company. As of 2007, its principal shareholders are Nantes Métropole (65%), the transport group Transdev (14.99%), banking group Caisse d'Epargne (10%) and the Chambre de commerce et d'industrie de Nantes (10%). It has been responsible through renewable 6 years "public service delegations", for the public transports of Nantes since it was formed in 1979, although the precise area covered has varied over the years.

## Organization

Currently, the TAN network comprises three Tramway lines, one Busway line, two Navibus lines, an extensive bus network that includes 56 lines and a night bus network. Additionally, Semitan has an exclusive agreement with French national train operator SNCF to allow TAN passengers to ride suburban trains within the urban area limits with a valid TAN ticket or pass.
TAN also operates "Navette Aéroport" (airport shuttle bus) between downtown Nantes and Nantes Atlantique Airport.

## Fares

The TAN network in Nantes uses paper tickets and passes along with contact less smart cards. There are no travel zones on the network in Greater Nantes. Tickets and passes allow free transfer and are universally valid on the Tramway, Busway, Nantes buses, Navibus, and suburban trains within Nantes Métropole. Ticket machines (which accept cash and credit cards) are present at every Tramway and Busway stations. There are also some staffed ticket offices open for limited periods only. Also, most newsagents sell some tickets and passes.
Like many public transport systems in Europe, TAN operates on a proof-of-payment system. The network is patrolled by fare inspectors equipped with handheld card readers. Passengers traveling without a valid ticket are straightaway asked about their identity and fined €46.50 (amounts may vary depending the nature of the infraction).
