what is it?

The SNCF Class Z 22500, also known as the MI 2N "Éole" (French: Matériel d'Interconnexion à 2 Niveaux, lit. 'Interconnecting Bilevel Set'), is a double-deck, dual-voltage electric multiple unit (EMU) operated on RER E, part of the Réseau Express Régional (RER), a hybrid suburban commuter and rapid transit system serving Paris and the surrounding Île-de-France region. The Z 22500 is the version of the MI 2N series operated by the SNCF. It closely resembles the MI 2N "Altéo" variant operated by the RATP Group, although the two variants differ in their motorization and interior layout. A total of 43 five-car trainsets were built by a consortium of Alstom (then GEC Alsthom) and Bombardier.
