As work on the new Réseau express métropoltain (REM) progresses, part of the Mount Royal tunnel will be reduced to one track next month, which make all trips through the tunnel about five minutes longer.Starting on March 25, crews will begin work at track level to build the Édouard Montpetit station that will link to the métro’s Blue Line station of the same name, so 1.5 kilometres of the tunnel will be closed off. Exo, the region’s commuter train authority, said because the affected area is also where there is a switch for the track, only one train will be able to pass through the tunnel at a time. Trains will have to wait at each end of the tunnel, which will add about five minutes to each trip to and from Central Station.Schedules for the Mascouche and Deux Montagnes train lines will be adjusted to reflect the changes.For the Deux Montagnes line, the last Friday departures from Central Station will be cancelled and the train that now leaves at 4:35 p.m. from Deux Montagnes will also be cancelled. There will be no changes in the number of departures from Monday to Thursday, but the times of some trains will change slightly, so riders should consult schedules posted on the Exo’s website.The changes are less dramatic for the Mascouche line, where the number of departures will stay the same, and the departure times will vary by five minutes at most.Exo says the schedules of the buses serving the Deux-Montagnes, Terrebonne and Repentigny stations will be changed to reflect the new train schedules.Starting at the end of May, the Canora and Mount Royal stations will be merged into one until the line is shut down in early 2020 for a period of two years. A new temporary platform will be built in between both stations, and that will mean users of either station will have to walk about 250 metres farther, or less than a five-minute walk, Exo said. The temporary platform will be deployed over the long weekend May 18-20 and it is expected to be functional on May 21.REM is a $6.3-billion electric driverless light-rail network that will connect the existing Deux-Montagnes Line to the South Shore over the new Champlain Bridge, and also to the airport and the West Island along the Trans-Canada Highway. The first stations are slated to open in 2021, and the full network is slated to be up and running by 2023.Related email@example.com/jasonmagderfacebook.com/jasonmagderjournalist
