The VB2N (, "two-deck suburban car") is a double-deck passenger car used on Transilien suburban rail services in the Île-de-France region of France. The cars are unpowered and designed to be paired with an electric locomotive. The coaches, built from 1974, are the successors of the Chemins de Fer de l'État's 1933 built Voiture État à 2 étages. They are currently in use on Line J of the Transilien network. They were previously used on RER lines C and D, Transilien lines H and K as well as services between Gare de l'Est and Tournan station, which became the RER E. Since 2012, the VB2N trains have been shifted from busier RER and Transilien lines to less busy routes on Transilien network as new equipment comes online, most notably the single-level Z 50000 "Francilian" and double-deck Regio 2N (Z 57000) trainsets. The VB2N trains are scheduled to be completely retired by the end of 2022. Description The VB2Ns are designed to be used in push-pull mode, although the cars are not powered, there is a control car at one end of the train so that the locomotive does not have to run around its train at the terminus. Passenger space is divided in two levels. Each end of coach is a vestibule from which two separate sets of stairs lead to the upper and lower-decks. The walkway and seating on the lower deck is situated below platform level to gain space and avoid unnecessary height. The upper-deck is relatively spacious as height is restricted although adults may walk standing up. All coaches have toilets apart from both end carriages. Next stop is announced vocally and visually. Speed is limited to .
