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). In 2004, the STIF (regional transit authority) began the tendering process for approximately 180 new EMUs to replace SNCF's aging stainless-steel single-deck suburban fleet.

SNCF Class BB 30000 BB 30001 followed in 1974. SNCF Class BB 30000 The SNCF Class BB 30000 electric locomotives were built by Fives-Lille, CEM and MTE in 1961. They were the tri-current version of BB 9400 "Vespa" locomotives, of which they were closely derived, and inherited much of the knowledge of the experiences of BB 20004. With electrification of the mayor European axes pending in the late-1950s, SNCF engineers dreamed of a locomotive type which could operate of all 4 major European currents: 1.5 kV DC, 3 kV DC, and .
