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 French: «Nouvelle Automotrice Transilien», which was its project name).

History and design[edit]

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; this stock nicknamed inox (short for [acier] inoxydable: stainless steel) comprised EMUs Classes Z 5300, Z 6100, Z 6400 and similar push-pull trainsets known as RIB-RIO (Rame Inox Banlieue, Rame Inox Omnibus.[note 1]). Alstom, Siemens and Bombardier were initial involved in the bidding process.[4]

In 2006 Bombardier obtained a contract from SNCF and STIF for 172 ‘Francilien’ trainsets, with an option for 200 more.[5] (cost €1.850 billion.[1]) The design was for a train operating a typical journey of 30 to 50 km (31 mi) length, including numerous stop lasting 30 to 40 seconds,[6] and able to operate from either 1.5 kV DC or 25 kV AC overhead line electrification.[6]

The vehicles use an articulated design using Jakobs bogie intercarriage articulation. of seven or eight carriages; seating layout is [3+2] formation giving over 400 seats in a seven-car unit, over 500 in an eight-car set. Total occupation exceeds 800 (or 1000 in eight-car trains) including standing passengers at 4 per square meter.[3][5][7]

The vehicle's width is 3.06 metres (10.0 ft), wider than previous trains, which is achieved by having a short standard carriage's length of 13.24 metres (43.4 ft).[6][8] The inter-carriage passages are wide, limiting bottlenecking.[8]

All interior lights are provided by light-emitting diodes (LED), so power consumption is lessened.[6]

The Z 50000's appearance refers to three main entities: green leaves evoke Transilien, red doors evoke SNCF, and a long grey banner on each side evokes the Syndicat des transports d'Île-de-France (STIF).[9]

Introduction and operations[edit]

Bombardier presented the Spacium vehicle at Crespin on 6 February 2009;[10] the first unit delivered for commercial operations to the SNCF was the unit ‘Z 50015/16’, also numbered #8, on 21 October 2009.[citation needed]

The first service operated by a Francilien train was on Line H from Paris Gare du Nord to Luzarches on Sunday 13 December 2009;[11] as of December 2018, 360 trainsets had been ordered, and about 240 were in active service.[12]
