January 2020 - Replacement of railway tracks
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.
- 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 early 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.
