SNCF Regio 2N: double-deck and dual-voltage electric multiple unit trainset

SNCF Regio 2N

The Regio 2N is family of a double-deck, dual-voltage electric multiple unit trainsets built for French rail operator SNCF to serve its regional rail routes (TER, Transilien, and RER).

The trains utilize a unique and highly configurable design. One of the end cars is single-deck and designed to accommodate wheelchair users, the other end car is double-deck. The intermediate cars are either double-deck with no doors accommodating seated passengers traveling long distances or single-deck with two double doors per side accommodating standing passengers traveling short distances. Trains can be configured with six, seven, eight or ten cars. Additionally, the seating can be configured for intercity service (2+1 seating in 1st class, 2+2 seating in 2nd class), regional service (2+2 seating throughout), or high-capacity commuter service (3+2 seating throughout).

The train was designed and originally built by Bombardier, but during delivery the company was bought by Alstom, which completed the order. A total of 447 trainsets have either been built or are under construction at the Alstom Crespin factory since 2012. The first set was placed into regular passenger service in September 2013.

The name Regio 2N is a sensational spelling of the word “region” (in reference to the regional rail routes these trains serve) including SNCF’s designation for double-deck rolling stock: 2N (French: 2 Niveaux, English: two-level). Bombardier brands this equipment as the OMNEO and SNCF classes it as Z 55500, Z 56300, Z 56500, Z 56600 or Z 57000 depending on the configuration.
