SNCF Class Z 50000 SNCF Class Z 50000 The SNCF Z 50000 is an electric multiple unit train built by Bombardier Transportation (manufacturer's designation SPACIUM 3.O6) for the French rail operator SNCF, for use under Transilien operations in the Île-de-France. It is commonly called ‘Francilien’, and sometimes ‘NAT’ (for , which was its project name).
