Deux-Montagnes and Mascouche

This space contains the latest news, construction site activities, and frequently asked questions about the REM and the Deux-Montagnes and Mascouche lines.

Why do we need a new transit system?

In the next few years, the REM will ultimately replace the Deux-Montagnes commuter train line. It will service the same stations, but will also offer new connections: Correspondance A40 (Mascouche line), Édouard Montpetit (blue line) and McGill (green line).

Improved service on the Deux-Montagnes line was necessary in the long term, given its current and anticipated future saturation. Once commissioned, the REM will multiply the line’s capacity (5 times more departures). During peak hours, there will be departures anywhere from 2.5 to 5 minutes.

Work and alternatives

Starting April 27, 2018

Preparatory work will start resulting in a permanent closure of service during weekends on the Deux-Montagnes and Mascouche lines.

To remember: closure of service on Friday night (see below), weekends and public holidays.

Starting June 25, 2018

A segment of the Deux­-Montagnes line will run along a single track in the Ville Mont‑Royal sector so that new stations can be built. The schedule for the Deux-Montagnes and Mascouche lines will have to be reorganized.

To remember: significant changes to the train schedules and four trains cancelled (902, 914, 915, 952).

Starting in early 2020

In early 2020, and for approximately 24 months, the entire segment of the Deux‑Montagnes line between Du Ruisseau and Central Station will be replaced by a bus service. Train service will have to be interrupted due to the scope of the work, i.e. the construction of new stations and the installation of new rail systems.

To remember: closure of the segment between Du Ruisseau and Central Station (service will be maintained between Deux‑Montagnes and Du Ruisseau).

Alternative transit services will be presented in the fall of 2019.

Governance and public consultations

With a view to minimizing the impact of this large-scale construction site on Deux‑Montagnes and Mascouche line users, the ARTM has set up a specific governance structure. Committees of experts meet on a regular basis to identify the impacts and decide which alternative public transit measures to implement during the various phases. Among the preferred alternatives for users of the Deux‑Montagnes line, (where service will be maintained between the Deux‑Montagnes and Du Ruisseau stations) is a shuttle system to the western branch of the Montréal métro’s Orange Line. Various information activities will also be organized with users, and user committees will be set up in collaboration with Trajectoire Québec. The final strategy for providing transit services to Deux­-Montagnes and Mascouche line users will be presented in the fall of 2019.

REM in service

The primary differences between REM and the current Deux-Montagnes train service are:

  • More frequent service. REM will operate 20 hours a day, 7 days a week, with departures every 5 minutes during peak hours and every 15 minutes in off-peak hours between Deux-Montagnes and Sunnybrooke stations. Between Bois-Franc and Gare Centrale stations, trains will depart every 2.5 minutes during peak hours and every 5 minutes in off-peak hours.
  • Greater capacity. REM will have a minimum transportation capacity of close to 22,000 passengers between 6:30 and 9:30 am, 5,000 more than the existing transit network can carry.
  • New connections to metro lines. REM will connect to Montréal’s three existing metro lines: the blue line via station Édouard-Montpetit, the green line via station McGill and the orange line via station Bonaventure (Gare Centrale).
  • More destinations. REM will connect you to Montréal-Trudeau Airport, Technoparc Montréal, the South Shore and parts of the West Island, all within a single transit network.
  • Different cars. REM trains are not commuter trains. They are more like metro cars from a technological standpoint. REM cars are smaller but will run much more frequently, which explains the substantially increased capacity.
  • Enclosed and universally accessible stations. You will wait for REM trains indoors, on a platform separated from the tracks by automatic screen doors. All stations will be universally accessible.

Yes, the capacity of the Deux-Montagnes line will be much higher.

REM cars are smaller than MR-90 cars, but run much more frequently due to the high frequency of the light rail metro line. Thus, the REM provides a higher capacity per hour and per day.

 

For example, during the morning peak period (from 6 to 9 a.m.):

  • With the REM

Maximum capacity of a metro: 780 passengers
Number of departures from 6 to 9 a.m. : 54 departures (36 at Deux-Montagnes, 18 at Bois-Franc coming from the airport)
780 x 54 = 42,120 passengers

  • With a MR-90 train

Maximum capacity of a train: 1,900 passengers
Number of departures from 6 to 9 a.m.: 9 departures (6 at Deux-Montagnes, 2 at Roxboro-Pierrefonds, 1 at Bois-Franc)
1,900 x 9 = 17,100 passagers

 

To learn more, read our article: The REM, seating and capacity

There are 120 seats available.

REM cars are smaller than MR-90 cars, but run much more frequently due to the high frequency of the light rail metro line. It means that the number of seats will not be greatly affected if we look at the entire peak period.

 

For example, during the morning peak period (from 6 to 9 a.m.):

  • With the REM

120 seats
36 departures at Deux-Montagnes
18 additional departures at Bois-Franc coming from the Airport
120 seats x (36 departures + 18 departures) = 6,480 seats with REM during the morning peak period

  • With a MR-90 train

900 seats
6 departures at Deux-Montagnes
3 additional departures at Roxboro-Pierrefonds and Bois-Franc
900 seats x (6 departures + 3 departures) = 8,100 seats with REM during the morning peak period

 

To learn more, read our article: The REM, seating and capacity

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.

Generally speaking, our approach is to promote public transit. To do so, we have worked hard with transit companies in the past year to optimize feeder bus service to REM stations. We do not yet have the details of this reorganization, which is still in the planning stages, but our overall objective is to increase bus frequencies and the areas that they service, including buses from neighbouring cities, toward the various REM stations.

Current parking areas on the Deux-Montagnes line (Deux‑Montagnes, Grand‑Moulin, Sainte‑Dorothée, Île‑Bigras, Roxboro‑Pierrefonds, Sunnybrooke, Bois‑Franc, Du Ruisseau) will, for the most part, remain the same.

Mascouche line

The arrival of the REM means that users of the Mascouche line will have to transfer at a brand-new station (Correspondance A40) located just past Ahuntsic train station, if you are heading downtown.

The new Correspondance A40 station will be expressly designed to ensure smooth transfer of users between the Mascouche line and the REM. Station equipment will optimize traffic (wide corridors, elevators, shared platform, etc.).

As soon as you leave the commuter train, you will walk on a covered platform, then enter a closed station, sheltered from inclement weather. Once aboard the REM, the trip from Correspondance A40 Station to Central Station will take approximately 10 minutes. Total trip time to downtown for Mascouche line users will be equivalent to the current travel time.

The high frequency of the REM (2.5 minutes during rush hour) will mean fast boarding for users and reduced waiting times. Lastly, when heading downtown on the REM, you will be able to get off at new stations: Édouard-Montpetit, connected to the blue metro line, and McGill, connected to the green metro line. In the opposite direction, you will also be able to travel straight to the airport from this connection.
