Green Line (Montreal Metro) Green Line (Montreal Metro) The Green Line (), also known as Line 1, is one of the four lines of the Montreal Metro in Montreal, Quebec, Canada. The line runs through the commercial section of downtown Montreal underneath Boulevard de Maisonneuve, formerly Rue de Montigny. It runs mainly on a northeast to southwest axis with a connection to the Orange and Yellow Lines at Berri-UQAM, and with the Orange Line west of downtown at Lionel-Groulx. The section between Atwater and Frontenac was part of the initial network; the line was extended to Honoré-Beaugrand in 1976 to provide easy access to
Blue, Green, and Waterfront Lines (Cleveland) Green Lines on the same platform, an arrangement unique in North American rail transit. The shared stations have low platforms for the Blue and Green Lines directly adjacent to high platforms for the Red Line. RTA Central Rail yards and headquarters are located at the East 55th station, where trains of all rail lines are stored and serviced. East of East 55th, the Blue and Green Lines split from the Red Line and travel east on a separate, dedicated, grade separated right-of way. A complex of tunnels existed at this junction to provide means for the Blue and Green Line
