GO Train This is a commuter train, the name is GO, that's why I play with the title. 3:30 - 4:00 PM is start of rush hour, so they were getting the trains ready to to take the commuters to the suburbia.
The railways in Canada were necessity 100 years ago, but the car rules now!
One candidate for Mayor of Toronto recently (Fall 2010) suggested to make tunnel to bring more cars to the city center.
He will not be elected, but a lot of people still think this way in North America.
