Try the following tour, recommended by residents or metro enthusiasts:
Pick a copy of the leaflet "Galeries d'Art" from a ticket couter and explore the artworks in the stations. Most rewarding are the legs of Line A between Marengo SNCF and Reynerie and Line B between Francois Verdier and Canal du Midi. As the small trains run every 3 minutes, it is easy to hop off and on at every station to take a look at the concourse levels which are also worth seeing.
VAL family Members: Chicago (O'Hare Airport people mover), Lille, Paris (Orlyval, CDGVal airport trains), Rennes, Taipei, Toulouse, Turin, Uijeongbu, Characteristics: Sleek, small, automated, rubber-tyred metros. Platforms are usually short and have platform screen doors.
Before doors close there's a buzz like in Paris. After departure, a female recorded voice says "Prochaine station: [name]" ("Next station: [name]"), and repeats the station name once again before the train stops. Before transfer stations, she adds: "Correpondance: ligne [line name]".
