Line 2 (Orange Line) was gradually extended westward to station in 1980 and to station in 1981. As the stations were completed, the service was extended. In December 1979 Quebec presented its "integrated transport plan" in which Line 2 (Orange Line) was to be tunnelled to Du Collège station and Line 5 (Blue Line) from station to Anjou station. The plan proposed no other underground lines as the government preferred the option of converting existing railway lines to overground Metro ones. The mayors of the MUC, initially reluctant, accepted this plan when Quebec promised in February 1981 to finance future extensions fully. The moratorium was then modestly lifted on Line 2 (Orange Line) that reached Du Collège station in 1984 and finally station in 1986. This line took the shape of an "U" linking the north of the island to the city centre and serving two very populous axes.
