This line was extended to Simonis the next year and opened as metro line 2 in 1988, from Simonis to the South Station. Crainhem/Kraainem and Stockel/Stokkel also opened that year on line 1B. At the other end of this line, Bizet opened in 1992. It was then the turn of line 2 to reach Clemenceau in 1993. The "premetro" section known as the North-South Axis, sometimes referred to as line 3, was extended to Albert that year with five new "premetro" stations (South Station, Porte de Hal/Hallepoort, Parvis de Saint-Gilles/Sint-Gillis Voorplein, Horta and Albert).
