The Z 2N (French: Automotrice Z à 2 niveaux, English: two-level Z series) is a family of double-deck electric multiple unit trainsets that are operated on the Réseau Express Régional (RER), a hybrid suburban commuter and rapid transit system and the Transilien, a suburban commuter rail system, both serving Paris and its Île-de-France suburbs.^[1]

Variants

There are five variants of the Z 2N that have been produced:

The Z 5600 is the original version of the Z 2N, it is a single-voltage trainset (1.5 kV DC). 52 trains were built between 1982 and 1985 by CIMT [fr], TCF, and TCO. Currently the type is primarily assigned to the RER C line, and the TER Bourgogne-Franche-Comté line.
The Z 8800 added dual-voltage capabilities (1.5 kV DC and 25 kV AC). 58 trains were built between 1985 and 1988 by ANF, CIMT, and TCO. Currently the type is assigned to the RER C line, and the Transilien N and U lines.
The Z 20500 is dual-voltage capable and is an improved version of the Z 8800. 194 trains were built between 1988 and 1998 by Alsthom, ANF, and CIMT. Currently the type is assigned to the RER C and D lines, and the Transilien P and R lines.
- The Z 92050 is mechanically identical to the Z 20500, but with a different class number because they were purchased by the Nord-Pas-de-Calais region for TER services. The trains were purchased by the Île-de-France region in December 2012 and refurbished to more closely resemble the rest of the Z 20500 class. Six trains were built in 1996 by GEC-Alsthom, ANF, and CIMT. Currently the type is assigned to Transilien Line P.
The Z 20900 is dual-voltage capable and is an improved version of the Z 20500. 54 trains were built between 2001 and 2004 by Alstom and Bombardier. Currently the type is assigned to the RER C.
