Another interesting city from a transit perspective is Amsterdam. The subway stop spacing is so wide that all the tourist destinations can only be reached from downtown by streetcar or bike (ex Van Gogh museum). Everyone uses streetcars on busy pedestrian streets or bikes or walks, and it works as well.
Brussels was interesting too. I went on an underground streetcar line (basically a subway with light rail or streetcar vehicles like central Eglinton will be), with the same vehicles that we're ordering. There were also buses & streetcars at extremely high frequencies on all streets (every 2-3 minutes it seemed), but they often had their own lane aka ROW on the street. Buses definitely had bus lanes on many narrow roads.
Here's a photo I took of an incredibly frequent streetcar:
