Overview of Line 1 : Green Line
Line 1, commonly called the green line due to its color on the map, was one of the initial lines of the Montreal Metro when it started in 1966. It originally had 10 stations from Atwater to Frontenac which were all in the Ville-Marie borough, which represents Downtown Montreal.
On June 6th, 1976, the line was extended to the East to Honoré-Beaugrand in order to have access to Olympic Stadium, which hosted the Olympics. This extension added 9 stations, all Mercier-Hochelaga-Maisonneuve borough, going to the East, which made 19 stations. Then on September 3rd, 1978, it was extended for 8 stations to the West to Angrignon, making 27 stations for this line. This brought the metro to Le Sud Ouest and Verdun borough.
Rolling stock was the MR-63 made by Canadian Vickers from 1966 to their retirement in 2018. They were replaced by MR-73 made by Bombardier (which also had replaced trains on this line occasionally since 2008) and by MPM-10 (called Azur) by Bombardier and Alstom.
The frequency of trains is 3 to 5 minutes at peak hours, 4 to 10 minutes at non-peak hours, and 6 to 12 minutes on weekends.
Trains are stored at the Honoré-Beaugrand garage at Honoré-Beaugrand station.There is also another garage, Angrignon garage at Angrignon station, as well as two workshops.The Viau workshop is between Viau and Pie-IX station. There are also extra tracks between those stations that let trains park there so when events at Olympic Stadium ends, the trains can start from there to downtown, just like the Mets-Willets Point station does in New York. The final workshop is the Duvernay workshop between Lionel-Groulx and Charlevoix. Trains can also switch line with line 2 there, just like they can do at Berri-UQAM (with lines 2 and 4).
There are two transfer stations, Berri-UQAM transfers with lines 2 and 4 and Lionel-Groulx with line 2.
The majority of stations have side platforms. Lionel-Groulx has island platforms (with the other line) while Charlevoix and De L'Église have stacked platforms.
