Alstom will supply 15 Citadis Dualis for the Ile-de-France region after an SNCF exercise of option on behalf of STIF. The order, which is part of the framework agreement signed in 2007 on behalf of the French regions, amounts to a total of approximately $108 million.

The delivery of the 15 Citadis Dualis tram-trains will begin in summer 2016 for an expected commercial operation of July 2017 on the Epinay-sur-Seine and Le Bourget sections of the TLN line.

Designed to meet the need for increased fluidity between the urban and suburban transport networks, the Citadis Dualis is the link between the city center and the suburbs without passenger interchange, balancing the benefits of train and tram. With a design based on Alstom's Citadis tramway, the Dualis features the core characteristics that created its success: modularity, accessibility and reliability.

The Dualis model is equally capable of running on both tram and regional rail networks, through adaptations concerning the power, safety and comfort. This configuration makes it a versatile mode of transport: the tram gauge allowing inner-city transport, and its train performance enabling it to transport passengers to the outskirts without the need to change modes of transport.
