Work
The REM will gradually replace the Deux-Montagnes line in 2022 and 2023.
Work in 2019-2020 will mainly consist of building new covered stations between Gare Centrale and Du Ruisseau, which will require closing the Mount Royal tunnel and complete suspension of commuter train service between these two stations.
Geotechnical surveys and relocation of public and municipal utilities will continue along the route, in order to provide data that is critical for designing the REM’s stations on the North Shore.
Even though construction of the Laval and Deux-Montagnes stations will only begin in 2022, preparatory work will begin in the coming months.
Île-Bigras and Sainte-Dorothée stations
In 2019-2020, the main work in the area will be the construction of new railway bridges for REM traffic, on both sides of the Laval Islands. Between Montreal and Laval, we are building a brand new two-track rail bridge, adjacent to the existing rail bridge, while the bridge located north of the Islands will be doubled.
The sequence of railway bridge works involves:
-
The construction of abutments, located on the shoreline and designed to support the weight of the bridges
-
Drilling of foundation caissons and their anchoring to rock
-
The construction of piers and headers, where the reinforcement cages are installed at a height, before the concrete is poured using a mould
-
Installation of the beams and then concreting of the bridge deck
Around mid-2021, when the complete interruption of service on the Deux-Montagnes commuter train line occurs, construction work on the two stations will begin.
Grand-Moulin and Deux-Montagnes stations
The Deux Montagnes station building, which will eventually be demolished, was closed to the public in December 2018; signs were posted on all four doors.
In Saint-Eustache, construction is nearing completion on the temporary garage for exo trains. This garage will allow us to convert the permanent exo maintenance centre so it is compatible with REM cars.

FAQ
North shore
All stations of the current Deux-Montagnes line will be served by the REM. Édouard-Montpetit (blue line) and McGill (green line) stations are added to the existing line, favoring connection with the metro. Of course, the REM will also connect you to Montréal-Trudeau Airport, Technoparc Montréal, the South Shore and parts of the West Island.
No pedestrian traffic is planned for the Roger-Lemoine woodland nature reserve. Users will access the station by way of the existing streets.
New infrastructure will be built for the REM route and our teams are still analyzing whether the existing bridges will be dismantled or maintained, and what use will be made of them.
For the commissioning phase of the project, we intend to maintain current sound levels and will take the necessary steps to keep noise impact to a minimum during the operations.
NouvLR, the consortium in charge of REM construction, is currently taking sound measurements all along the network in order to refine the models. Now that the consortiums for the construction and the rolling stock have been selected, we know which type of vehicle will be used and have a better understanding of how sound will travel in the REM’s right of way. The models being developed will serve to determine the mitigation measures to be put in place.
When assessing the noise impact of the REM, we must bear in mind the following:
- The REM is a light rail transit system (LRT), which makes REM trains quieter than conventional trains.
- REM trains will run more frequently but will have much shorter train sets (numbers of cars), meaning that it will take less time for them to pass by the area.
- REM train cars will have quieter braking systems.
- Mascouche line trains (which are louder than REM trains) will no longer travel past Mont-Royal station.
- REM cars will be modern and quieter.
- Because of the new A40 station, REM cars will travel through the area at a slower speed.
It is important to note that with the REM, a number of sources of railway noise will be reduced, particularly noise resulting from engine propulsion, aeration/cooling fans and the rubbing and squealing of the wheels on the tracks. Other sources of noise will be eliminated entirely, including disc brake rubbing, whistling on arrival at the station, and grade crossing alarms.
