Network Access

The Network is open from 5.30 am until 1.00 am average. Train schedules may vary depending on the line. We advise you to check your route using the Transilien home page.

Find the best route

For a pleasant visit of Paris, travel preferably outside of rush hour which usually is from 8.00 to 10.00 am and from 5.00 to 7.00 pm.

To find your path to the Paris region network, look for these logos on street signs:

  • To take a Transilien commuter train, look for its letter and associated color TransilienN
  • To take a RER train, look for the RER logo, its letter and associated color B
  • To take the metro (subway), look for the letter M, its number and associated color Métro1

In order to access the network, you must have a valid ticket (or Navigo pass). You must validate it before you access the train.

The Île-de-France network is divided in 5 fare zones:

  • The t+ ticket is valid on all metro, bus, and tram lines, as well as on the RER train, only in zone 1.
  • For any other trip, you should buy an Origin-Destination ticket, a Navigo Day Pass or Navigo Week Pass (for example, for: Charles de Gaulle Airport, Orly Airport, Versailles, La Défense).

Check out the fare zones map


You may buy your ticket at the machine or at a ticket office. Find them by folllowing the signs or ask a Transilien agent.

On the machine, you may pay:

  • with a credit card from €1
  • cash (€40 maximum)

The machines that are accessible to disabled people and accept foreign credit cards have a specific sticker.

At the ticket office, you may pay:

Rules of Conduct and Fines

When you enter the station until you exit, keep your valid ticket with you:

  • Your ticket is valid on the train and metro for 2 hours (except the t+ ticket which is valid for onehour and a half) after validation.
  • In order to exit most stations, you must validate your ticket so the gates open.
  • The validity of your ticket may be checked at any time in the station or aboard the train by our agents. When asked, show your valid ticket and the elements to justify a reduced fare if you have one.

If you cannot show a valid ticket, you wil be fined €50, with an extra €50 if you do not pay immediately (should your ticket be unvalid, the fine will be €35).  If your Navigo Pass is not validated, you will be fined €5, with an extra €50 i you do not pay immediately.

Customer Service

If you need help with your ticket, go to a SNCF, Optile or RATP ticket window.

To avoid demagnetization of your tickets, we recommend not storing them near a smartphone or a magnet (handbag buckle, glasses case, magnetic buttons, keys...).

Platform Access

To pass through the access gates: walk to the left of the green arrow and insert your ticket in the slot or validate your Pass on the purple magnetic reader. Do not forget to take your ticket once validated and keep it until the exit.

If the gates are already open, validate anyway. Otherwise, you will be liable to pay a fine in case of control.

Some stations in Île-de-France operate with validation terminals, please validate before accessing the platform.

To reach the right train, RER or subway platform, find the number of the metro line, the RER / train line letter and the line terminus.

In order to take the line in the right direction, check the direction and your exit station on the signs.

RER trains do not always stop in all stations, check on the display screen that your destination is there.

  •     For your convenience, elevators & escalators are available in many railway stations.
  •     If you take the escalators, make sure you stand on the right to let people wishing to climb quickly on the left.

  • it weighs less than 13 pounds (≤ 6kg)

Guide dogs are accepted free of charge on trains, subways, trams and buses.

For larger animals, especially dogs that must be leashed and muzzled, you must buy a half-fare ticket.

  • Monday to Friday before 6:30 am, between 9:30 am and 4:30 pm and after 7:30 pm (between rush hours)
