Some commuters will have to wait a bit longer to board the city's new automated light-rail line. Three segments of Montreal's REM (Réseau express métropolitain), from downtown to the North Shore and West Island, now aren't projected to open until the end of 2024. That's a postponement for the central (from Gare Centrale to the borough of Saint-Laurent) and West Island segments, which were supposed to open in fall 2023 and spring 2024, respectively. The previous schedule already put the opening of the line to Deux-Montagnes on the North Shore in fall 2024.
