Sucy–Bonneuil 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.

The station is served by a train every ten minutes at off-peak time in both directions, and every 15 minutes at late evening and early morning.
