The various moratoriums and technical difficulties encountered during the construction of the fourth line stretched its realization over fourteen years. This Line 5 (Blue Line), which runs through the centre of the island of Montreal, crossed the east branch of Line 2 (Orange Line) at the station in 1986 and its west branch at the Snowdon) station in 1988. Because it was not crowded, the STCUM at first operated Line 5 (Blue Line) weekdays only from 5:30 am to 7:30 pm and was circulating only three-car trains instead of the nine car trains use on the other lines. Students from the University of Montreal, the main source of customers, obtained extension of the closing time to 11:10 pm and then 0:15 am in 2002.
