What are the two REM directions being tested?

REM Montreal is testing short-turn trains that end at the Bois-Franc terminus, and through trains that continue as A4 Deux-Montagnes. This split pattern helps concentrate capacity where demand is highest while maintaining a direct option for longer trips, which aligns with the operating plan expected when the A3 segment opens.

Will this change my travel time or require a transfer?

It depends on your station and train. If your train ends at Bois-Franc, you may need a cross-platform transfer to continue. Through A4 Deux-Montagnes trains will run direct. Check platform signs and train fronts for direction, and plan a brief buffer during the testing phase.

How long will the testing last and when does A3 open?

The operator is testing ahead of the A3 Anse-a-l’Orme launch planned for this spring. The exact test duration was not specified. Expect refinements as data is collected. Follow official updates for day-by-day notices, service adjustments, and confirmation of the opening window for A3 service.

What should investors monitor during this phase?

Focus on on-time performance, average peak and off-peak headways, transfer wait times at Bois-Franc, and rider communications quality. Consistency across several weekdays would support a smoother ramp after A3 opens. Also watch local sentiment and footfall near stations, which can signal early retail and service demand shifts.
