For awhile now, Montrealers have been asking for 24 hour Metro service. The only problem is that it's actually impossible to do that with the system we have.
The only networks that can do this, have parallel lines, so they are able to close one line while people travel on the other.
Luckily the STM does make a few exceptions, and last year they announced that for the first time ever, they would be keeping the metro open all night long on New Year's Eve.
And they're doing it again this year!
That means no matter how much you drink, and no matter how late you decide to party on December 31st, the STM will be there to make sure your drunk ass gets home safely.
