Gare d'Austerlitz
Automatic crowd-control gates known as "portillons automatiques" were once present in the majority of stations at the end of the corridors leading to the platforms. Introduced from the 1920s to regulate passenger access to crowded platforms, their usefulness was never properly demonstrated and from the 1960s they were withdrawn from service. Most have been dismantled, but non-functioning examples can still be found at Charles de Gaulle – Étoile and Gare d'Austerlitz.
