From May 1963 to December 1964, like the majority of the stations of line 1, its platforms were lengthened to 90 meters to accommodate trainsets of six cars to cope with significant chronic overloads. On 21 October 1964, the station was the first to be equipped with moving walkways, 132 meters long, in the corridor connecting its northern and southern parts. Like most of the stations of line 4, between October 1966 and October 1967, the platforms of the latter were in turn extended to 90 meters, in order to accommodate trains of six pneumatically-driven carriages.
