About the network

From metro and RER to suburban trains, the Noctilien night bus, trams, and buses, different modes of transport are available to take you everywhere in Paris and the surrounding region, both day and night.

Several carriers, one network

Many means of transport and interconnected lines make the Île-de-France network your key to travel across the entire Paris area.  On a day-to-day basis it is overseen by the Syndicat des Transports d’Île-de-France (STIF), and operated by three carriers: SNCF Transilien, RATP and OPTILE.

The Syndicat des Transports d’Île-de-France (STIF) is the organising authority for public transportation in Paris and the surrounding area. It covers the Île-de-France region, the city of Paris, and 7 other departments in the region, and is in charge of:

  • designing, organising, and financing the entire public transportation network for Île-de-France (trains, RER regional trains, underground, trams, T Zen and buses),
  • bringing every stakeholder together (elected officials, equipment manufacturers, carriers, infrastructure managers, etc.) to improve the services we bring to passengers,
  • commissioning and managing transportation modernisation projects, which are run by SNCF Transilien, RATP and OPTILE.

Transilien and RATP work together to make sure the network in Paris and the region runs smoothly. They are responsible for:

  • on-time operations for the lines they operate,
  • safety of passengers and employees,
  • quality of service for passengers (customer service, information, cleanliness),
  • modernisation and development of the public transport network. The two carriers share management of the various means of transport and network lines, and they jointly operate certain RER lines (A and B) and the Noctilien night bus.

Finding your way in a station

When you are in a metro or RER station, you can use the signs to find what you are looking for.

To ask an employee a question about an itinerary or about purchasing a ticket, for example, you can go to an information desk. You can find them by following the directions indicated on station signs.

It's easy to find the line you want using numbers and/or colour codes (metro), or letters (RER) and/or endpoints. Once you've identified your line, follow the arrows that show the way. Make sure you're taking the line in the right direction, by checking its endpoint and the station you'll be stopping at.

To leave a station, follow the signs that say "Sortie" ("Exit"). Walk through the exit door, which may open automatically or manually.

Elevators & escalators Station signs will inform you about the stairs, escalators, and elevators you can use to get around.

Purchase your ticket

There are several different ways to purchase a ticket.

In every station you will find machines where you can quickly purchase your origin/destination tickets, as well as Mobilis, Paris Visite, Youth tickets and t+ tickets. You can pay:

  • in cash,
  • or with a bank card, with a minimum of €1. Some machines accept foreign bank cards with magnetic strips (€40 maximum).
  • Some machines are accessible to people with limited mobility. You'll be able to recognize these machines thanks to their specific visual characteristics.

In stations, with our employees in Optile, RATP, and SNCF sales agencies, and in certain RATP "comptoir-club" windows, you can buy most of the tickets you would need to get around in Paris and the surrounding region:

  • in cash,
  • or with a bank card, with a minimum of €1. Some machines accept foreign bank cards with magnetic strips (€40 maximum).

  • For your entire trip, including transfers If you have an origin/destination, Mobilis, Paris Visite, ticket Jeunes or t+ ticket, you can use it for just one trip, with no interruptions except for connections. The use of two complementary tickets is not authorized. After validation, your ticket is valid on the rail network, including the metro for 2 hours (except for the t+ ticket, which is valid for 1 hour and 30 minutes). If you wish to interrupt your trip, the portion you have not travelled will not be reimbursed
  • From the station entrance to the station exit Keep your ticket and take care of it until you leave the station. Transilien and RATP employees can verify the validity of your ticket in stations and in trains at any time. During an inspection, present your validated ticket, as well as the supporting documents if you are claiming a discounted fare. If you are found not to have a validated ticket during an inspection, you'll face a fine of €45, with additional administrative costs.
