A terminal loop was provided at the station for trains to turn around to return north towards Porte de Clignancourt.
The extension to Mairie de Montrouge modified the layout of the station, the northbound platform was extended toward the track coming from the former terminal loop to add a new entrance.
In 2013, line 4 was extended south into Montrouge, with a future extension toward Bagneux planned.
The station is named after the Porte d'Orléans, a gate in the nineteenth century Thiers wall of Paris, which led to the town of Orléans via the road now known as route nationale 20, or N20.
On the west side of Rue de la Légion Étrangère is Square du Serment-de-Koufra, a park commemorating a pledge made by Leclerc on 2 March 1941, the day after taking the Italian fort at Kufra, Libya: he swore that his weapons would not be laid down until the French flag flew over the cathedrals of Metz and of Strasbourg.
