[2][3][4]

The SNCF Class Z 50000, also known as the 'Francilian', or 'NAT' (for French: Nouvelle Automotrice Transilien, English: New Rail car Transilien, the project name) is a type of dual-voltage electric multiple unit trainset designed in the 2000s. It is used on the commuter rail system serving Paris and its Île-de-France suburbs on the Transilien network. Departing stations are Gare du Nord, Gare de l'Est and Gare Saint-Lazare.

A total of 360 trainsets have either been built or are under construction by Canadian conglomerate Bombardier at its Crespin, France (near Valenciennes) 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.

History

[edit]

In 2004, the Syndicat des transports d'Île-de-France (STIF, the transit authority for the Paris region until June 2017) 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 [fr]) and RIO (Rame inox omnibus [fr]). 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 1,500 V DC or 25 kV 50 Hz AC overhead catenary electrification.[5]

Alstom, Bombardier, and Siemens all submitted bids for the project.[6] In 2006, SNCF (French Railway Company) and Syndicat des transports d'Île-de-France (STIF, the transit authority for the Paris region until June 2017) 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.[2][3]

Bombardier presented the Spacium vehicle at Crespin on 6 February 2009.[7] 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.[8] As of December 2018, 360 trainsets had been ordered, and about 240 were in active service.[9]

Design

[edit]

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 ft 0 in), which is wider than previous trains, achieved by having a relatively short car length of 13.24 metres (43 ft 5 in).[5][4] The inter-carriage passages have wide, open gangway connections, limiting bottlenecking.[4] All interior lights are provided by light-emitting diodes (LED), so power consumption is lessened.[5] Technical details: SPACIUM Environmental Product Description.[10]

Technical characteristics

[edit]

The dual-current capacity (1,500 volts DC and 25,000 volts AC) enables the train to serve the entire Ile-de-France network. Its electrical consumption is 20% lower than that of equipment in circulation in 2009. The two traction motors per bogie are of the three-phase asynchronous type; they operate at a voltage of 380 volts - 50 hertz. The motorization is distributed over five motor bogies, located at each end, in line with the driving cabs, and between cars 2 and 3, 3 and 4 and 6 and 7 (in the long version) or 5 and 6 (in the short).

A train is divided into two distinct sets of traction chain, cars 1 to 4 on the one hand and cars 6 to 8 on the other hand. Each of these half-elements has two traction chains in parallel, redundancy which reduces the risk of unavailability in the event of a breakdown. The Z 50000 are distinguished by another specific feature: in normal operation, only 80% of the available power, or 2,950 kW (3,960 hp) for one element, is used. In the event of failure of one of the engine blocks, the other engines are actuated at 100% in order to ensure the normal operation of the train.

The acceleration reaches 0.9 m/s2 (2.0 mph/s) for the eight-cell configuration and 1 m/s2 (2.2 mph/s) for the seven-cell configuration. The deceleration reaches −1.05 m/s2 (−2.3 mph/s) during service braking.

Formations

[edit]

As of 1 March 2022, 339 Z50000 trainsets (01H to 346L).

8 cars sets

[edit]

The 8-cars trainsets are formed as shown below, with five motorised cars and three non-powered trailer cars (5M3T) more precisely with 5 motorized bogies jacobs and 4 trailer bogies.

They are based at the Noisy le Sec (Line E and P), and les Joncherolles /St Denis (Line H and K) depot.
