Reminds me a bit of the PATH trains in NYC/NJ except these subways are clean!
Took the Metro the other day to get to the Jean-Talon market (great place) to wander around, eat, and pick up some fresh fruits to nosh on for breakfast in our room.
Went from Sherbrooke station to Jean-Talon station. What struck me most were how clean their stations are. Not one piece of garbage or paper on the platforms, or on the tracks. The train cars were also very nice and clean. Clear announcements of each stop. Well lit. Trains come and go pretty frequently. There are even recycle bins on the platforms - hey NYC MTA take note!
Kiosks to purchase tickets and manned booths if you need some help with directions. Pretty easy to understand the rail system here and the color designated lines. Not too bad on prices depending on the pass you need.
Only drawback are that the trains are just not air conditioned enough. It was on but I prefer it much colder when it's 85 degrees out. Still, a nice way to get around the city and explore.
