The lines awarded on 12 October 2023 by the Île-de-France Mobilités Board of Directors represent important axes of the Ile-de-France rail network with:
- 70,000 trips per day,
- 900 daily train crossings ,
- and 32 stations or stops served.
A first vote that marks the gradual launch of the competition of the lines then operated by SNCF Transilien.
What are the missions of a line operator?
As part of the award of a public service contract, the Keolis and SNCF Voyageurs consortium becomes the operator of the lines awarded for a period of seven years. A period during which the company will assume:
- Traffic and service on the lines concerned,
- The management and maintenance of rolling stock,
- The management of adjoining service facilities, such as the Noisy-le-Sec tram-train maintenance and handover site, for example,
- Station management,
- Infrastructure management.

A unique and recognizable identity
As you may have noticed, the new trains, metros, trams and buses in the Ile-de-France region are wearing the same colours, those of Île-de-France Mobilités. A visual identity that allows, at a glance, to recognize transport that is part of the Île-de-France network or not.
