Caption: Hustle and bustle of the city streets on a warm summer's day. With pedestrians, cyclists and cars going about their merry way, TTC CLRV 4061 waits to make the turn onto Spadina Avenue from King Street. While some runs of the 510 go to the end of the line at Union Station via Queen's Quay, a number of 510s turn at King and head back up Spadina, to the street's namesake station at Bloor.
