So at this point, why do they run the train up to there? The answer is they shouldn't.
On the other hand, if the REM would go to Vaudreuil or Rigaud, the costs would be mostly for infrastructure and low costs for running cars per km, lower than a bus and no pollution.
It's a gross generalization but I'm definitely wondering why people are sold on commuter trains.

It would be interesting to see the CO2 emissions of an 8-car commuter train vs say 850 cars on the road or 20 buses (the amount of buses it would take to carry those 850 commuter rail users to their destination). I don't know how precise this list is, but the calculations I made are as follow:
A diesel car = 133,5 grams of CO2 per km, so for a 40km trip it would be 5,340 grams of CO2 per km
For 850 cars = 4,5 tons of CO2
A diesel bus = 892 grams of CO2 per km, so for a 40km trip it would be 35,680 grams of CO2 per km
For 20 buses = 0,71 ton of CO2
A diesel train = 3912 grams of CO2 per km, so for a 40km trip it would be 156,480 grams of CO2 per km
There is only one train for those 850 users so the number isn't multiplied

As a matter of fact, the train in itself pollutes more than one car or bus but far less than the number of cars or buses it would put on the roads if it didn't exist. I may be wrong, if someone can correct me in my analysis.
