Fontenay-sous-Bois station is on the Ligne de Vincennes [fr] railway.

From 1859 to 1969 the Ligne de Vincennes ran between Paris–Bastille station and Marles-en-Brie.

On 14 December 1969 Paris–Bastille station was closed and the line was rerouted into a new 2.5 km (1.6 mi) tunnel under Paris between Nation and Vincennes stations, creating the first line of the Regional Metro network, later renamed the Réseau Express Régional.

[2] The station is served by a train every 10 minutes at off-peak time in both directions.
