Although the Citadis units are only 4 articulated sections, they come to a total length of 42m, have a width of 2.65m, have an axle load of 11.5t and have a total capacity of 250 passengers (90 seated). It is possible to form double or triple units to increase capacity. Citadis units are equipped with air-conditioning and on-board display systems. Units sport the livery of Île-de-France Mobilités, the organisation ultimately responsible for the Montfermeil extension, of white & silver with celeste trim. The first car was delivered to the Noisy depot on 2 November 2017.
