Stations in this sector
The construction of the REM in the Town of Mount Royal, as well as in the boroughs of Côte-des-Neiges-Notre-Dame-de-Grâce, Saint-Laurent and Ahuntsic-Cartierville, has gained momentum in recent months. Among other things, the Jean-Talon, Cornwall and O'Brien stations and overpasses have been built.
The Canora and Ville-de-Mont-Royal sector
Work on the Cornwall Bridge and the dalle park will be completed in 2022. They will be turned over to the Town of Mount Royal so that it can start to build a new public square.
Interior finishing work (painting, ceramics, etc.) will continue throughout the year, as will the landscaping work.
The Ahuntsic-Cartierville and Saint-Laurent sectors
2022 will see the start of construction of the Toupin Boulevard viaduct and the continuation of work on the O'Brien viaduct as well as the multifunctional passage linking the boroughs of Saint-Laurent and Ahuntsic-Cartierville, near the Du Ruisseau station.
Lastly, the complete transformation of the railway tracks will continue west of the Du Ruisseau station with the installation of anti-intrusion fences and the hydroseeding of the embankments in preparation for the REM.
Center and Airport
The REM will run in part on existing rail corridors. To ensure this high-frequency network is safe, grade crossings will be eliminated. In places where grade crossings currently exist, the road will be raised or lowered or the railway track will be elevated. (The REM will run on an elevated track above the road.)
The technology chosen for the REM is an automated metro. This type of technology is quieter than heavy trains (no whistle at station arrival or alarm at grade crossings, electric brakes, etc.).
While the REM’s rolling stock was designed to minimize noise, once the light rail is in operation, sound may be audible.
REM construction and operation are governed by a regulatory framework established by the Government of Québec. Noise modelling was performed to assess the anticipated noise that the REM in operation will generate and to determine mitigation measures that may be required, such as erection of permanent noise walls along the route.
A large number of inputs were programmed into a specialized software to produce this REM sound model, including:
- Removal of noise from Exo trains on the Deux-Montagnes line
- Addition of REM noise, taking into consideration frequency and speed, structure elevation, route curves, various operating scenarios, etc.
- Consideration of ambient noise, road traffic, topography, proximity of residential areas, etc.
On the Deux-Montagnes branch, trains will be quieter than commuter trains, but more frequent. Noise barriers will be installed on certain segments between the Canora and Deux-Montagnes stations.
Required mitigation measures will be implemented before the REM is commissioned.
