Deux-Montagnes and Mascouche

This space contains the latest information about work of the REM and alternate transportation options for the Deux-Montagnes and Mascouche lines.

Why do we need a new transit system?

The REM will gradually replace the Deux-Montagnes line in 2022 and 2023. This line needs to be upgraded over the long run as it is congested and would be unable to accommodate all users in the coming years.

The work involves replacing the train system with an automated electric metro system. The tracks and power supply will be changed and enclosed, heated stations will be built.

Ultimately, the implementation of a new metro technology will make it possible to significantly increase train departures and by extension, the line’s capacity (2.5 times more people will be able to board the REM during peak morning and evening hours). The REM was conceived to effectively handle traffic for many decades to  come.

Work schedule

The REM work will take place in several phases in order to maintain service on the Deux-Montages and Mascouche lines for as long as possible.

Work phases

Preparatory work consists of geotechnical drilling and surveying. This data is essential for assessing soil resistance and finalizing the design plans.

Impact: permanent closure of service on Friday nights and weekends on the Deux-Montagnes and Mascouche lines

Alternate routes for the Deux-Montagnes line

Alternate routes for the Mascouche line

The Deux-Montagnes and Mascouche lines are now running on a single track (previously a double track) in the Ville Mont-Royal sector so that new stations can be built.

Impact:
- Schedule changes for the Deux-Montagnes and Mascouche lines
- More traffic on the trains and possible overflow at certain departure times; users are invited to adjust their schedules or use the alternatives offered (especially for the stations in Montréal)

New schedules for the Deux-Montagnes line

New schedules for the Mascouche line

The Gare Centrale Du Ruisseau segment will be closed for about 24 months. This closure is necessary due to the magnitude of the work to install the new rail systems.

Impact:
- Closure of the Gare Centrale – Du Ruisseau segment (the Du Ruisseau – Deux-Montagnes segment will remain in service)
- Service interruption on the Mascouche line at the Ahuntsic station

Transportation alternatives will be announced in fall 2019. Buses will transfer passengers from the Deux-Montages line to the metro’s orange line (West side). Users of the Mascouche line will have the option to transfer to Sauvé station.

The REM will be operational on the  Gare Centrale – Du Ruisseau segment. Construction will continue on the Du Ruisseau – Deux-Montagnes segment (planning underway, more details to come).

Impact: Closure of the Du Ruisseau – Deux-Montagnes segment

Transportation alternatives will be announced at a later date. Buses will transfer passengers from the Deux-Montages line to the metro’s orange line (West side) and/or to a REM station.

End of works. The REM will be fully operational.

Alternate routes

Developing new habits

The alternate transportation options for 2018-2019 are proposed by Greater Montréal’s transit companies (STM, STL, EXO). Users of the Deux-Montagnes line are invited to get into the habit of leaving a little earlier or later to avoid the possibility of overflow traffic at the stations.

Alternate routes for the Mascouche line (2018-2019)
New schedules for the Mascouche line

The complete strategy for 2020-2023 will be presented in fall 2019. The transit companies will use the next few months to develop effective alternatives. At the same time, we have created a users’ committee and are holding consultations in collaboration with Trajectoire Québec.

FAQ

Deux-Montagnes and Mascouche lines

Departure frequency. The REM will operate 20 hours a day, 7 days a week, with departures every 2 min 30 during peak hours and every 5 min in off-peak hours between Gare Centrale and Bois-Franc. Between Bois-Franc and Deux-Montages , trains will depart every 5 min during peak hours and every 15 min in off-peak hours.

Capacity. The capacity on the Deux-Montagnes line will increase significantly. For example, during morning peak hours between 6:00 a.m. and 9:00 a.m., the REM will serve 42,100 people (compared to 17,100 currently).

New connections. The REM will connect to Montréal’s three existing metro lines: blue (Édouard-Montpetit), green (McGill) and orange (Bonaventure). You will also be able to get to the Montréal-Trudeau Airport, Technoparc Montréal on the South Shore and the West Island.

Different cars. REM trains are not commuter trains; their cars are more like metro cars from a technological standpoint. REM cars are smaller but will run much more frequently, which explains the significant increase in capacity. The space will be designed for smooth passenger flow at transfer station entrances and exits (poles, bars, wider spaces). They will be air conditioned and equipped with bicycle and luggage racks.

Equipped stations. REM stations will be enclosed, covered, climate controlled and sheltered from the elements. You will  wait for the REM on a platform separated from the tracks by an automated screen door system (it will no longer be possible to drop objects on or to cross the track; safety and reliability will thus be improved). All stations will have elevators and be accessible to persons with reduced mobility.

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.

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

There are several reasons for the recent service disruptions on the Deux-Montages line.

Since June 25, 2018, REM work has required exo to operate the Deux-Montagnes and Mascouche trains on a single track on a stretch of about 3 km between Montpellier station and the Mont-Royal tunnel. A double track allows trains to pass each other and contributes to smooth operational flow.

Operating on a single track gives exo less leeway in the event of a prolonged incident. Here is an example of the domino effect of a single track:

Medical intervention on July 13, 2018

  • 3:35 p.m.: a passenger on train 939 heading to Deux-Montagnes collapses.
  • 3:37 p.m.: the train has to stop on the single track. An exo inspector begins CPR to resuscitate the passenger.
  • 3:38 p.m.: the departure of train 941 to Deux-Montagnes is delayed.
  • 3:55 p.m.: emergency services arrive at the scene.
  • 4:15 p.m.: emergency services leave the scene. Train 939 can resume operation after being stopped for 39 minutes.
  • 4:50 p.m.: the departure of train 945 to Deux-Montagnes is delayed.
  • The departures of trains 947, 949, 951, 953 and 957 to Deux-Montagnes are also delayed.  Train 946 (to Gare Centrale) is cancelled.
  • Between 3:00 p.m. and 12:30 a.m., 15 trains left Gare Centrale for Deux-Montagnes. Of these 15 departures, 8 were delayed because the times where they could pass another train on a double track train no longer matched. As a result, that day the order of train traffic had to be changed.
  • Some trains on the Mascouche line were also affected.

As well, the rail cars on the Deux-Montagnes line, the MR-90, have passed over half of their useful life and are not running optimally due to their advanced age. A mechanical and electrical upgrade of the MR-90 cars has begun. However,  since the rolling stock is used to maximum capacity, the crews can only remove a limited number of cars at a time from service to perform the work. As a result, cars that need repairs must be kept in service. Equipment breakdown is one of the reasons for service disruptions.
