Start of preparatory work on the Deux-Montagnes line for the Réseau express métropolitain

Montréal Published on

An initial seres of alternative transit methods will be available to Deux-Montagnes line customers beginning Friday, April 27.

The Réseau express métropolitain (REM) project office has announced the start of preparatory work on the Deux-Montagnes line this spring and summer, which will require the implementation of alternative transit methods each weekend, beginning Friday, April 27, 2018 at 8 p.m.

As a result of this preparatory work, train service on the Deux-Montagnes line will be suspended each Friday night and last through 4 a.m. Monday morning. The work will also affect Mascouche line services on Friday night.

In order to be able to re-position the rolling stock to the proper locations when service is restored on Monday morning, the last departures on the Deux-Montagnes and Mascouche lines will be:

Deux-Montagnes line:

  • Last departure toward Central Station: 6:33 p.m.
  • Last departure toward Deux-Montagnes: 7:30 p.m.

Mascouche line:

  • Last departure toward Central Station: 5:17 p.m.
  • Last departure toward Mascouche: 7:12 p.m.

The REM project office will coordinate all interventions and work required for the REM construction and completion. Weekend closures will continue once these initial preparatory tasks are complete, as construction on the new train stations will begin. A comprehensive construction schedule for 2018 will be published toward the end of April, and will confirm the other interventions required on the Deux-Montagnes line. Meanwhile, various mitigation measures will continue to be organized with ARTM and other transit companies.


Rapid set up of mitigation measures for public transit users

Under the Autorité régionale de transport métropolitain’s responsibility, with collaboration from Mobilité Montréal, in charge of coordinating and mitigating traffic issues in the Greater Montréal area, as well as Réseau de transport métropolitain (RTM), Société de transport de Montréal (STM) and Société de transport de Laval (STL), alternative public transit options will be offered to Deux-Montagnes commuter train passengers who ordinarily use this service on Friday night and on weekends, for the entire duration of the REM preparatory work.

An initial series of alternative methods will be implemented on Friday, April 27, and will be effective each weekend until a new order is issued. Among the options that will be available in this series is an express bus service that will run between the Montmorency metro station and the Deux-Montagnes and Grand-Moulin stations. Enhancements to this initial measure will be announced in the coming weeks, including expanded public transit services in Laval and Montréal to service the Deux-Montagnes line stations in these regions.

Operational details relating to these measures will be released soon and communicated to transit customers within the framework of an informational campaign that will outline alternate schedules and bus routes.

Nature of the work

Coordinated by the REM project office, the work will initially consist of geotechnical investigation drilling, surveying and inspecting existing infrastructures. This very important step will provide critical data that will help to guide the consortium as they design the REM’s structures and stations.

To ensure construction workers’ health and safety, electrical power supply to the Deux-Montagnes and Mascouche lines will be cut off while work is carried out.

REM project office

The REM construction project office has been launched. The project office team will be responsible for coordinating, along with the selected consortiums, all of the construction work on this new, 67-km public transit network featuring 26 stations.

Coordination will be in cooperation with all of the municipalities and boroughs that the REM route travels through, as well as the Mobility partners throughout Greater Montréal. 

In addition to a website dedicated to REM construction information (, other tools will be available to monitor REM construction progress including a newsletter and SMS alerts.  A community relations office will also be set up to ensure close communication with our citizens.


Prochaines étapes pour le REM

The REM construction schedule for the next year will be announced before the end of April 2018. All information regarding the nature of the work will be accessible on the REM website.

About the REM

The Réseau express métropolitain (REM) is a new, 67-km integrated public transit network that will feature 26 stations and link downtown Montreal, universities, South Shore, West Island, North Shore and Montréal Trudeau airport through a fully automated, electric light rail system.

About the ARTM

The Autorité régionale de transport métropolitain’s mandate is, most specifically, to elaborate the strategic development plan and integrated rate schedule, and to finance the public transit and paratransit services for the greater Montréal area. It will be responsible for ensuring all services are efficiently integrated throughout its territory and for establishing the objectives and standards for these services.

In order to fulfil this mandate, the Autorité will draw from best practices already implemented in many organizations. Its goal is to serve the 500 million annual users by facilitating their mobility and access to services by means of a simple, integrated and efficient public transit experience. To do so, the Autorité wants to become an agent of change, enabling the driving forces in the public transit industry to coalesce around a unified vision.


About the RTM

Since June 1, 2017 the RTM has merged the Agence métropolitaine de transport’s (AMT) public transit expertise in trains with the bus transit expertise of companies on the north and south shores (CIT and MRC). RTM is responsible for operating the regular public transit bus and train services, including paratransit services for the Communauté métropolitaine de Montréal (Montréal Metropolitan Community) (82 municipalities), the Kahnawake First Nations reserve, as well as the City of Saint-Jérôme.
