Line 10
Michel-Ange - Auteuil

Even though this station is right in the middle of the loop, it has two tracks. The reason for this is explained further in the next station, Porte d'Auteuil. Basically, it was originally envisaged that these tracks would host special Line 9 trains heading towards Porte Molitor. Because the other track is permanently fenced-off, only one track is used now.
