Much like Line 3bis, this station used to provide a through service to Pré Saint-Gervais. Line 7bis became a line unto itself in 1967, and when this happened, the platform arrangement changed in a radical way. One set of platforms caters for Line 7 Eastbound and Line 7bis Departures, the other for Line 7 Westbound and Line 7bis Arrivals. Once a train arrives at the Arrival platform, it reverses onto the "Z" siding, then runs into the Departure platform to pick up passengers. The driver at the other end then takes the train out towards Pré Saint-Gervais.
