Platforms

Louis Blanc consists of two underground stations built on different levels. The shallowest is nicknamed the upper station, the other the lower station. They have the same particular configuration with a side platform, described as "dead" because of its non-use, and an island platform bordered on both sides by the subway tracks. One of the two tracks is therefore framed by the two platforms, while the other runs along the right wall. The upper station is served, from the central track, by the trains of line 7 running to Mairie d'Ivry or Villejuif - Louis Aragon and, from the side track, by the trains of line 7 bis from or to Pré-Saint-Gervais, of which it previously provided only arrivals. The lower station is served, from the side track, by the trains of line 7 to La Courneuve, while its central track, previously ensuring the departure of trains of line 7 bis towards Pré-Saint-Gervais, is no longer used in normal service.

Both stations are decorated in the Ouï-dire style, yellow for the upper station and in green for the lower station. Thus, the lighting canopies are supported by curved hangers in the form of a scythe are yellow and green respectively. The direct lighting is white while the indirect lighting, projected on the vault, is multi-coloured. The white ceramic tiles are flat and cover the right wall, vault and tunnel exits, but the technical room at the western end of the upper station is treated with classic bevelled white tiles. The advertising frames are yellow or green (matching the lighting banners) and cylindrical, while the name of the station is inscribed on enamelled plates with the Parisine font for the upper station, and in capital letters as in Parisine typography for the lower station. The Motte style seats are yellow in the upper station and grey in the lower station.

Other connections

The station is also served by lines 26, 46, and 54 of the RATP bus network, and at night, by lines N13, N41, N42, and N45 of the Noctilien bus network.
