The Voiture de banlieue à 2 niveaux (English: two-deck commuter car), shortened to VB2N, is a type of double-deck passenger railcar used on Transilien, the commuter rail network in the Île-de-France region of France.

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.

Since early 2019, the VB 2N trains on the Transilien Line J are gradually being replaced by the Z 50000 "Francilian" single-level electric multiple unit (EMU) trainsets.

Starting in 2021, the VB 2N trains on the Transilien Line N are scheduled to be replaced by new Regio 2N (Z 57000) double-deck EMU trainsets.
