The new Deux-Montagnes REM line began running at 5:30 a.m. on Monday with service every 10 minutes, increasing to a frequency of 4 minutes 30 seconds during peak periods. That higher frequency will remain consistent throughout the day.
After years of delays, this extension of the light-rail network is now fully open, connecting the North Shore to downtown. The Deux-Montagne’s extension adds 14 stations between downtown Montreal and the North Shore.
Following a busy open house weekend, the REM’s operator, Pulsar, reported a strong start.
