The Transilien (pronounced [tʁɑ̃ɛ̃]) is the brand name of the suburban railway service of the SNCF-owned railway network operating within the Île-de-France région. "Transilien" is a derivative of Francilien, the demonym for people living in Île-de-France.

Transilien trains depart from Paris' main railway and RER stations (although many city-centre RER stations are run by the RATP) and the western business district of La Défense. Transilien services transported 615 million passengers in 2004.


The first line to the suburbs of Paris was opened on the 26 August 1837. The route went from Paris-Saint-Lazare to Le Pecq. The railway link was thought of as key to the western suburbs. On 1 October 1972, the line was handed over to the RER, and commenced service as the RER's ligne A.


The Transilien is divided into six key entities, which are divided according to SNCF guidelines and are unrelated to the departmental boundaries. The lines are then divided into branches which, similarly to the RER, are given letters. However, until 2005, the letters were unknown to the wider travelling public.

The six Transilien entities are:

The system is slightly complicated; each different entity has very different structures. Key complications include:

  • The power supplies
  • The numbers of branches
  • The lack of onward transportation beyond the termini
  • Density of trains on the network
  • The mix of traffic on the railway including express trains, freight trains, long distance trains, Transilien trains and RER traffic.

The glitches in the network are visible at times when SNCF staff go on strike or serious technical problems occur on the network. Thousands of travellers arrive late for work or even, when there are serious problems, decide not to go into work, which causes a large financial burden to companies.

Because of the extent of the lines, a concentric zoning system is used. Trains that are bound for the outer zones are normally operated as express trains and are nonstop until the outer zones to reduce travel time.

Rolling stock[edit]

The rolling stock used on the Transilien comes from a long evolution of the material in the suburbs. The following stock is used on the network:

On January 16, 2002, during a ceremony at the Gare de Paris-Est, the President of the SNCF Louis Gallois, the Prefect of the Ile-de-France Jean-Pierre Duport and the Regional Chair Jean-Paul Huchon, presented the new liveries of Transilien.

The design used for the rehabilitation and rejuvenation of the fleet was conducted by two outside agencies under contracts awarded in October 2000. RCP Design Global provided exterior design and interior signage, and Avant Première the interior. All vehicles received a new blue and gray Transilien livery with panels of color to highlight doors and internal characteristics. Everything was treated with a graffiti- resistant coating to reduce the impact of vandalism. The trains are equipped with a new ergonomic design of seating with individual seats instead of the traditional banks. They are covered with vandal-resistant fabric in blue, yellow and red. Circulation and inter-car doors have been modified to improve the distribution of passengers in trains[2]
