The Z 2N (French: Automotrice Z à 2 niveaux, English: two-level Z series) is a family of double-deck electric multiple unit trainsets that are operated on the Réseau Express Régional (RER), a hybrid suburban commuter and rapid transit system and the Transilien, a suburban commuter rail system, both serving Paris and its Île-de-France suburbs.[1]
