It is commonly called ‘Francilien’, and sometimes ‘NAT’ (for (フランス語:«Nouvelle Automotrice Transilien»), which was its project name). ==History and design == In 2004, STIF began the tendering process for approximately 180 new trains, ''Nouvelle Automotrice Transilien'' (NAT) to replace the railcars nicknamed ''INOX'': SNCF Z 5300; Z 6100; and trains using RIB-RIO (''Rame Inox Banlieue'', ''Rame Inox Omnibus''.〔See :fr:Rame inox de banlieue, and :fr:Rame inox omnibus, on French language wikipedia〕) push-push trainsets.
