Update on Deux-Montagnes branch construction work

Project progress
Published on

The Deux-Montagnes branch will form the backbone of the REM. Here is an update on current construction sites and changes to come in the spring.

 

Schedule update and temporary platform at Canora–Mont-Royal

Construction continues at Canora and Mont-Royal stations on the west side of the track. Work completed in recent months includes excavation and backfilling of the platform, construction and anchoring of a retaining wall, and pile driving for the stations’ foundations.

The same work will be carried out on the east side on the other track during the spring, and operations in the Mont-Royal tunnel will intensify in the coming months. This step leads exo to operate on a single track over a longer distance inside the tunnel and requires two changes:

  • From March 25, 2019: updated schedules for the exo5 Mascouche and exo6 Deux-Montagnes lines. Schedules for a number of trains will be modified to maintain a regular service that can better adjust to contingencies. View the new schedules here: exo5 Mascouche / exo6 Deux-Montagnes
  • From May 21, 2019: exo trains will make only one stop at a shared Canora–Mont-Royal platform. The temporary platform is to ensure the safety of users and workers. It will be located between the two stations, approximately 250 metres and 5 minutes walking from each station (see the image below). Construction of new pedestrian accesses is planned for May 18-20, the date will be confirmed to neighbourhood residents and users shortly.

Saint-Eustache and Pierrefonds-Roxboro construction sites

We are already working on the construction of the future end-of-line maintenance centre at Saint-Eustache. Work is progressing rapidly and is unlikely to generate impacts because of the location.

Construction of Saint-Eustache maintenance centre

In the Pierrefonds-Roxboro area, we are currently finishing construction of an embankment running alongside the track. This will stabilize the ground in preparation for the doubling of tracks for the REM.

Preparing connections in the Mont-Royal tunnel

Major construction is underway at McGill (green line) and Édouard-Montpetit (blue line) stations. Starting this summer, operations in the Mont-Royal tunnel will intensify as work starts on the connection between the tunnel and the REM’s Édouard-Montpetit station. Construction of a new switch in the tunnel will allow exo to operate trains while the work continues until January 2020.

Upcoming steps in Saint-Laurent

In Saint-Laurent, construction of the A40 station starts this spring! This station will allow Mascouche line users to transfer to the REM and continue on to Édouard-Montpetit, McGill or Central Station. In the meantime, civil engineering work and archaeological digs will be carried out prior to construction of the tracks.

We will also be repairing the existing railway bridges over Henri-Bourassa, Grenet and Marcel-Laurin boulevards. Obstructions to car traffic lasting a few days may be put in place to facilitate the work. More information will be released shortly.

Annonce des mesures alternatives in the next few days

Public transit use frames everyday life. We are keenly aware that Deux-Montagnes and Mascouche line users want to know what measures will be put in place for the service suspension planned for 2020 (Central Station-Du Ruisseau segment). Public transit partners are working to finalize the transition alleviation strategy aimed at providing reliable transportation despite the suspension. Thank you for your patience. An announcement will be made in the next few days.
