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 East 34th–Campus station and the East 55th station are shared by the heavy rail rapid transit Red Line and the light rail Blue and
