The Réseau express métropolitain launched its first low‑speed, fully automated trains on the future line to Montreal‑Trudeau Airport during the week of August 13, 2026. The test runs mark the initial operation of the airport branch, which is slated for full completion by the end of 2027.
The automated trains are part of a broader rollout of the REM network, a new rapid‑transit system being constructed across Greater Montreal. The airport branch will link the city’s central transit corridors directly to the international airport, extending the reach of the network once the project is finished.
The trial operations involve the low‑speed vehicles traveling along the newly built tracks toward the airport. Engineers are monitoring performance, signaling, and safety systems as the line moves toward its final testing phase. Completion of the airport extension is scheduled for 2027, aligning with the overall timetable for the REM’s expansion throughout the region.
The commencement of these test runs demonstrates progress on the infrastructure that will integrate the airport with the city’s rapid‑transit network. When the extension becomes operational, it will provide a direct, automated link between downtown Montreal and the airport, enhancing connectivity for commuters and travelers alike.
