Alstom has announced that it will supply 15 Citadis Dualis tram-trains to the Ile-de-France region following the second exercise of an option by SNCF on behalf of Syndicat des transports d'lle-de-France, or STIF. The order, which is part of a framework contract signed in 2007 with SNCF for the French regions, is worth EUR 75 million. The Citadis Dualis tram-trains will be delivered from October 2017 onwards, and their entry into commercial service is scheduled for 2019 on the section between Livry-Gargan and Clichy Montfermeil.

Designed to meet increased mobility needs between urban and suburban networks, Citadis Dualis links the center of town with the suburbs without having to change trains, combining the advantages of the train with those of the tram. Designed along the lines of it's Citadis tram, the Dualis version retains the fundamental characteristics which secured its success: modularity, accessibility, reliability.
