The origins of
Île-de-France Mobilités can be traced back to the creation of
Syndicat des Transports Parisiens (STP). In 1991, the scope of responsibilities of the STP was extended to cover the entire Île-de-France region. Since 30 June 2020, a new kind of vertical platform screen doors, called
platform curtains, have been installed on platform 2bis of
Vanves–Malakoff station (in Paris region) on the
Transilien Line N commuter rail line.
Transilien stated their preference for such platform curtains for this line is due to the positioning of the doors not aligning across the
rolling stock, and that they plan to install them in other Transilien stations if the experiment is successful. In its coordinating role, STIF has been involved in the procurement of new rolling stock for multiple networks and lines, often in coordination with
SNCF. On 24 February 2010,
Bombardier Transportation announced that it had received a firm order for 80
Regio 2N trainsets, which included additional options for up to 860 total trainsets worth a total of . In January 2016, SNCF ordered additional 15
Alstom Citadis Dualis tram-trains on behalf of STIF, on top of an existing order for 15 identical vehicles. One year later, an consortium comprising
Alstom and Bombardier Transportation were selected to supply 255
X’Trapolis Cityduplex double-deck electric multiple units to replace aging rolling stock on lines D and E of the Île-de-France network under a €3.75 billion arrangement. In June 2015, a contract valued at €20 million was awarded to
Alstom Transport to develop and install an
automatic train operation (ATO) system on
RER A of the Réseau Express Régional network servicing Paris. At the time, RER A was the most heavily frequented regional line in Europe; the introduction of ATO enabled increased frequencies and improved performance on the line. During February 2017, it was announced that STIF and the public transportation company
Keolis had signed contracts valued at €750 million to partner on improving the bus network serving Greater Paris. Stated goals of these contracts included the trialing of new technologies, a reduction of
fare evasion, and a general raising of service quality. In June of that year,
Valérie Pécresse, President of the
Île-de-France region and of the STIF, announced that the authority would change its public name to Île-de-France Mobilités. The Île-de-France region inaugurated its first
urban cable-car system, the
Câble 1, on 13 December 2025, as part of a move to improve mobility for commuters and tourists alike. The line, operated by
Transdev and funded by Île-de-France Mobilités, is expected to carry about 11,000 passengers daily. ==References==
