The Class Z23500 also called TER 2N (TER 2 Niveaux) is a class of double-deck electric multiple units operated in France. They were built by GEC-Alstom and Ateliers du Nord de la France, (which became Bombardier) for SNCF and are used on the TER Network. These sets consist of 2 double deck coaches. They were built from 1997 and a total of 80 units were built. The units were ordered by the following regions: Provence-Alpes-Côte d'Azur, Nord-Pas-de-Calais and Rhône-Alpes. They are mainly used on stopping services around the French Riviera (Provence-Alpes-Côte d'Azur), Lille (Nord-Pas-de-Calais) and Lyon (Rhône-Alpes). They use the TER livery of their regions, e. g. the trains of Rhône-Alpes have a light blue livery.

During the 80's, Nord-Pas-de-Calais noticed massive growth of regional frequentation. The region ordered a first set of 6 Class Z 92050 in 1994 technically identical to Class Z 20500 to cope this situation. The Class Z 92050 offer a better power performance in comparison of tracted VO 2N and a satisfying capacity. Rhône-Alpes and PACA was also interested about the Z 2N series due to the growth of frequentation but wanted better amenagements for long distances. The Z 23500 serie is the first generation of TER 2N séries followed in 2004 by the Z 24500/ Z 26500 series also called TER 2N NG.
Following a tender Nord-Pas-de-Calais, Rhône-Alpes and PACA ordered 80 Z 23500 trainset (160 cars) to GEC-Alsthom and ANF in 1995.
SNCF completed a refurbishment programme of all of its Z 23500 sets in September 2022.[1]
