Blue Line (Montreal Metro) Blue Line (Montreal Metro) The Blue Line () is one of the four lines of the Montreal Metro in Montreal, Quebec, Canada. It was the fourth to be built, notwithstanding its alternate official name of "Line 5" (Line 3 was planned, but never built). Unlike the other three routes, the Blue Line does not serve the city's main Metro station, Berri-UQAM. The line is served by a single yard located between Parc and de Castelnau stations which is completely underground and occupies a small portion underneath Jarry Park. Another service facility is located at the 500-metre end tracks following Snowdon
Montreal Metro 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 College station and Line 5 (Blue Line) from Snowdon 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)
