The first new section opened on 30 June 1928, extending the line by 643 meters to Richelieu – Drouot from Opéra. With an increase in traffic forecast, at its 21 March 1926 meeting the Municipal Council of Paris decided to increase the new Line 7, 8 and 9 station length from 75 metres to 105 to use stock seven-car trains. Although lengthening the old stations was planned later, the work was never completed. The new Richelieu – Drouot station was the system's first 105-metre station, but train length was limited by the shorter stations.
