A total of 360 trainsets have either been built or are under construction by Canadian conglomerate Bombardier at its Crespin, France factory since 2006. The first set was placed into regular passenger service on 14 December 2009.

The name Francilien is also the demonym for people living in Île-de-France. The manufacturer brands this equipment as the SPACIUM 3.06, in reference to the 3.06 meter width of the cars, and the equipment has also sometimes been called NAT (for French: Nouvelle Automotrice Transilien, English: New railcar Transilien) which was its project name.

History and design

In 2004, the Syndicat des transports d'Île-de-France (STIF, the transit authority for the Paris region) began the tendering process for approximately 180 new electric multiple unit trainsets to replace SNCF's aging single-deck suburban fleet, including trainsets nicknamed “inox” (short for inoxydable, English: stainless [steel]) (Classes Z 5300, Z 6100, Z 6400) and similar push-pull trainsets known as RIB (Rame inox de banlieue) and RIO (Rame inox omnibus). The SNCF and STIF requested bids for a train design that could operate on a typical journey of 30 to 50 kilometres (19 to 31 miles) in length, including numerous stops lasting 30 to 40 seconds, and able to operate from either 1.5 kV DC or 25 kV AC overhead catenary electrification.[4]

Alstom, Bombardier, and Siemens all submitted bids for the project.[5] In 2006, SNCF and STIF awarded the contract to Bombardier with a firm order for 172 ‘Francilien’ trainsets at a cost of €1.85 billion, with an option for 200 more.[1][2]

Bombardier vehicle design is articulated using Jakobs bogies between the carriages. Seating is in a 3+2 layout giving over 400 seats in a seven-car unit, over 500 in an eight-car set. Total capacity exceeds 800 (or 1,000 in eight-car trains) including standing passengers at 4 per square metre (3.3/sq yd). The vehicle's width is 3.06 metres (10.0 ft), which is wider than previous trains, achieved by having a relatively short car length of 13.24 metres (43 ft 5 in).[4][3] The inter-carriage passages have wide, open gangway connections, limiting bottlenecking.[3] All interior lights are provided by light-emitting diodes (LED), so power consumption is lessened.[4]

Bombardier presented the Spacium vehicle at Crespin on 6 February 2009.[6] The first service operated by a Francilien train was on Transilien Line H from Paris Gare du Nord to Luzarches on Sunday 13 December 2009.[7] As of December 2018, 360 trainsets had been ordered, and about 240 were in active service.[8]
