Interesting locations and transit systems in that link. The downtown Toronto streetcars are not exactly what you'd call a "light rail system" but they would have a lot in common with some of them. The new streetcars pictured above do have that light rail look. Unlike downtown Calgary, where for the most part, the commuter trains are very much separated from car traffic, the tracks from the Toronto streetcars are not separated at all. (Somewhat like the San Francisco Cable Cars but not as hilly.) Consequently if you are in a hurry on a major n-s or e-w street, and you get behind a streetcar, it takes some maneuvering to get out in front. Streetcar drivers often get off the bus to yell at car drivers who pull up when their doors are still open. It's messy and gritty and there's a lot of mixing it up, unlike the pristine bus ride that flagamuffin was on above - which I suspect was 100% metaphorical.
